ABSTRACT Mini-grafting is a type of grafting that has been indicated to increase efficiency of forest and fruit species propagation. The aim of this study was to evaluate the mini-grafting technique as a method for propagation of guava grafted on intra or interspecific rootstock. The experimental design was randomized blocks, with four treatments, five replications and plots consisting of ten plants, in a 22 factorial arrangement, and factors consisted of rootstocks and canopy cultivars. Rootstocks used were Psidium guajava and Psidium guineense. The canopy used was Paluma and Cortibel 1 cultivars. Only thecanopy used had an effect on the percentage of grafting success of 52, 54, 82 and 84%, respectively, for ‘Cortibel 1’/P. guineense; ‘Cortibel 1’/P. guajava; ‘Paluma’/P. guineense; ‘Paluma’/P. guajava combinations. Mini-grafting was effective for guava propagation on intra or interspecific rootstocks. The average production time for ‘Paluma’ and ‘Cortibel 1’ saplings grafted on P. guajava or P. guineense, for mini-grafting, was 351 days, so that ‘Paluma’ seedlings were more vigorous than those of ‘Cortibel 1’.

Rooting Of Cuttings

In the commercial production of guava seedlings (Psidium guajava L.) the quality of the cuttings, homogeneity, high percentage of rooting are the factors important to be analyzed. Therefore, as the Século XXI cultivar is recent, it is necessary to do more studies regarding the behavior of this guava to the factors that aid in the rhizogenic process. The objective of this work was to verify the concentrations of indolebutyric acid (IBA) that provide the best rooting of cuttings herbaceous and semihardwood, as well as to verify the best kind of cuttings used for vegetative propagation the guava cuttings cultivar ‘Século XXI’. The experimental design was completely randomized in a 5 x 2 + 1 factorial design, beginning with five concentrations of IBA (0, 1000, 1500, 2000 and 2500 mg L-1), two kinds of cuttings (herbaceous and semihardwood) and one control treatment (immersed in distilled water for 12 hours), with four replications and 10 cuttings per plot. In relation of the variables: the percentage of cuttings live without roots, callus, number of roots and dry weight of shoots did not present significant interaction among treatments, not adjusting to any regression model. Therefore, concluding that the herbaceous cutting is the most indicated for the propagation of guava seedlings of ‘Século XXI’; The concentration of 2500 mg L-1 of IBA promotes a higher percentage of rooted semihardwood cuttings without leaf; The hormone solution diluted with alcohol 50% (v/v) resulted in toxicity for herbaceous and semihardwood cuttings cv. Século XXI.

In the western region of Paraná, the subtropical climate prevails, with little accumulation of hours of cold in the winter, making the fruit species not go into complete dormancy. Given the above, the objective of this study was to evaluate the effect of chemical defoliant on blackberry varieties, aiming at their complete defoliation and induction of numbness. The work was conducted at Unioeste, Marechal Cândido Rondon Campus, in a four-year-old orchard of plants, spaced 3 x 0.5 m, simple spreader with two wire strands at a height of 120 cm from the ground, and 20 plants per grow crops. The experimental design used was randomized blocks, where two treatments related to the application of defoliant (with and without) on 7 cvs were evaluated blackberry, containing three replicates and three plants in each cultivar. Was used as a defoliant lime sulfur applied in August pruning then held 25 days after application. Regarding fruit quality, Caigangue and Tupy varieties showed the highest SS/AT ratio, indicating the best flavor of their fruits for fresh consumption. The cultivars Brazos and Guarani showed lower SS/AT ratio, indicating more acidic fruits. Higher levels of ascorbic acid were found in fruits of cvs. Guarani and Cherokee. The application of defoliant reduced the total number of blackberry fruits of the cultivars Comanche and Guarani. The use of defoliant did not interfere in the physicochemical characteristics of the blackberry fruits of the evaluated cultivars.

The Passiflora L. genus covers a diversity of wild species with ornamental potential, especially due to the intrinsic beauty of its exotic flowers, flowering more than once a year and the lush foliage. However, Passiflora seeds present dormancy complicating seed germination and the establishment of commercial plant production with species with high ornamental potential. This study was conducted to determine the best pre-germination treatments to overcome seed dormancy for Passiflora quadrangularis, P. nitida, P. foetida, P. eichleriana, P. alata, P. cincinnata, P. mucronata, P. micropetala, P. suberosa, P. morifolia and P. tenuifila. The experimental design was completely randomized, with five treatments and four replicates, with 25 seeds per plot. Pre-germination treatments were: seeds soaked in 1,000 mg L- 1 GA3 (gibberellic acid) for 6 hours, seeds soaked in 0.2 % KNO3 (potassium nitrate) for 24 hours, seeds soaked in 1 % KNO3 for 24 hours, partial seedcoat scarification with sandpaper number 120 and control (seeds untreated). Percentage of germination, germination velocity index and radicle length were evaluated for all species. The results showed that GA3 was effective to overcome seed dormancy in P. suberosa (86%), P. morifolia (68 %) and P. tenuifila (54%). KNO3 1% had significant effect on overcoming dormancy in seeds of P. eichleriana (66%) and scarification with sandpaper increased seed germination of P. micropetala (38%).

The grafting of two cucumber scions (Cucumis sativus L.)—Taiko hybrid and Tsuyoi hybrid—onto a Tropical hybrid pumpkin rootstock (Cucurbita moschata L.) was studied. The study was conducted in a greenhouse. Plants grafted using the tongue approach grafting technique were compared with ungrafted plants. We evaluated the initial establishment of grafting through anatomical cuts on the region of union graft and examining leaves’ chlorophyll index (SPAD) and their levels of chlorophyll a, chlorophyll b and total chlorophyll. The experimental design utilized randomized blocks and the data were subjected to variance analysis (ANOVA) and the Tukey Test at 5% probability. The results indicate that Taiko cucumber scions are best grafted onto Tropical pumpkin rootstock, since these exhibits early grafting establishment. Moreover, when compared to grafting using Tsuyoi cucumber scions, Taiko cucumber scions present higher SPAD index values and levels of chlorophyll a and total chlorophyll.

The main purpose of the study was to identify the plant genetic resources (PGRs) affected by shrimp farming and to determine their magnitude of vulnerability. Data were collected from randomly selected 100 respondents, through personal interview, using an interview schedule, at Dumuria upazila of Khulna district, during 16 November 2009 to 15 February 2010. The fruit PGRs were more affected by shrimp farming than that of timber yielding and other types of PGRs. Among the 18-fruit PGRs available, all were endangered, except indigenous velvet apple, Diospyros peregrine (Gaertn.) Gürke, which was in threatened condition. Among the fruit species, banana, Musa acuminate; guava, Psidium guajava L.; jackfruit, Artocarpus heterophyllus Lam.; sapota, Manilkara zapota L. and betel nut, Areca catechu L. were in highly endangered. Among the 17-timber yielding and other plant species, only 7-PGRs were affected by shrimp farming while majority (10-PGRs) had been available in different extents. Among the vulnerable PGRs, bamboo, Bambusa bambos (L.) Voss; flame of the forest, Delonix regia (Boj. ex Hook.) Raf.; teak, Tectona grandis L.f. and banyan, Ficus benghalensis L. were endangered, while Indian ash tree, Lannea coromandelica (Houtt.) Merr.; ipil-ipil, Leucaena leucocephala (Lam.) de Wit and cool mat, Schumannianthus dichotomus (Roxb.) Gagnep. were in threatened condition. In general, the total fruit trees decreased in numbers (-74.17%) after inception of shrimp farming. On the other hand, the total numbers of timber yielding plants increased by 15.45%. From the overall consideration (irrespective of types), the number of plant population decreased (-58.10%) after inception of shrimp farming. It means that the plant species were affected by shrimp farming and became endangered. Int. J. Agril. Res. Innov. Tech. 11(2): 18-26, Dec 2021

Abstract Fopius arisanus (Sonan) (Hymenoptera: Braconidae) is a koinobiont solitary parasitoid of various fruit flies, particularly those in the genus Bactrocera. Researchers introduced F. arisanus into Africa for the biological control of Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), a pest of a wide range of fruit trees and vegetables. However, the suitability of host fruit species as egg-laying substrates for parasitoid development remains poorly investigated in tropical Africa. The present study examines the preference and performance of F. arisanus on B. dorsalis reared on eleven fruit species through laboratory choice-test trials. We assessed the oviposition activity, parasitism rate, developmental time, and offspring fitness of F. arisanus on nine cultivated and two wild host fruits species. Oviposition attempts were higher on Psidium guajava (L.) (Myrtales: Myrtaceae) and Mangifera indica (L.) (Sapindales: Anacardiaceae) than on the other host fruits tested. The wasp parasitized host eggs in P. guajava in no-choice experiments. Psidium guajava, Irvingia wombulu (Vermoesen) (Malpighiales: Irvingiaceae), and Irvingia gabonensis (Aubry_Lecomte) Baill (Malpighiales: Irvingiaceae) were suitable for parasitism in choice tests. Of all host fruits tested, the body and hind tibia lengths of both parasitoid sexes emerging from M. indica were longer than on the others. The female ovipositor was long on Annona squamosa (L.) (Magnoliales: annonaceae) and short on Eribotrya japonica ([Thunb.] Lindl.; Rosales: Rosaceae). We obtained the longest preimaginal developmental time for both sexes on E. japonica and the shortest for females and males on Carica papaya (L.) (Brassicales: Caricaceae). These results demonstrate the ability of some tested fruit species to serve for the permanent establishment of F. arisanus in the field.

ABSTRACT In this work, two cultural production systems were compared [conventional (CO) and organic (OR)], and its effects in the guava trees (Psidium guajava) bacterial blight (Erwinia psidii) control. The experimental design was in radomized blocks, in split-split-plot arrangement, where it was measured the bacterial disease and the fruits production on the 2005/06, 2006/07 and 2007/08 harvests. Four pruning seasons effects were evaluated on the harvests (September, December, March and June) in both production systems. Such systems were constituted of: OR – treatment with bioactive compound (BC), liquid BC and dead coverage, and; CO – chemical fertilization, fungicide and herbicide. In 2007/08, the area under the disease progress curve (AUDPC) of all the treatments in the OR system was lower (~54-107) than the CO one(~233-298). In the 2007/08 harvest the number of fruits for each plant for all the OR treatments was higher (~146-204) than the CO ones (~57-103). In all the harvests, considering all the treatments within each system, there was a significantly lower AUDPC (~93-184) and higher fruits production (~158-188) in the OR one than the CO one (AUDPC: ~208-476; fruits ~18-104). The pruning induced a higher AUDPC and lower fruits production in both production sytems.

<p>The study was conducted to develop local fruit plants and to improve vegetable production at the Plant Germplasm Garden of RC for Biotechnology-LIPI. Carambola (<em>Averrhoa carambola</em>), durian (<em>Durio zibethinus</em>) and guava (<em>Psidium guajava</em>) were propagated vegetatively (grafting and budding) and were grown on the media containing grass compost (K-1), spent compost of paddy straw mushroom (K-2) or oyster mushroom (K-3) in combination with rootstock length of 45-55 cm (TB-1), 65-75 cm (TB-2) and 75-90 cm (TB-3). Tomato (<em>Lycopersicum esculentum</em>) and <em>kangkung</em> (<em>Ipomoea reptans</em>) were grown on the same media in the screen house. The highest survival rate of grafted durian (71.56%) was obtained from TB-3 grown on K-1 by budding technique. Meanwhile, the highest survival rate of carambola (68.89%) was obtained from TB-1 by grafting technique. The budding technique was not appropriate for guava (0 % of survival). Application of K-3 of 3 kgs on tomato plants resulted in the highest fresh weight, length, and diameter of the fruit, and the highest of plant height, total leaves, and biomass of <em>kangkung</em>. The study is expected to be applied to improve fruit plant growth and survival rate as well as a high production of organic vegetable.</p><p><strong>How to Cite</strong></p><p>Priadi, D., &amp; Mulyaningsih, E.

The aim of this study was to determine the attacktion  intensity of  the bush rat (Rattus sp) in   Oil Palm smallholder at  Suko Awin Jaya Village, Muaro Jambi Regency. The research was carried out from February to April 2021 at the oil palm smallholder specifically  farmer group“Ridho Ilahi”. The experimental design was  unformated trials, and the location was purposively  chosen. The location determination of the sample was based on to  the initial survey that there was found     rats attacktion in this place. Sampling was carried out concurrently at the time  fresh fruit bunches harvesting,   fruit counting in the bunch, counting the number of fruits eaten by rats, counting good fruit (free from rat pest attacks), and weighing the weight of fresh fruit bunches. Parameters observed were the attacktion  level in the land, attacktion  intensity, production per hectare, environmental sanitation conditions. The rats attacktion  rate of  100%, means that all sample  in one stretch of   plantation  have been   attackted by rats, it was indicated by a bite scars on the harvested fresh fruit bunches. The attacktion intensity of the bush rat pest was 23%. The average production was 21.6 tons/hectare/year. The sanitation conditions on the land was partially overgrown with weeds and there were piles of midrib in the area between the certain two path of oil palm tree.
