Insight Into

Growth response of 22 accessions of Glycine javanica. was studied to detect any significant features that would provide an insight into the mechanisms of salt tolerance. Four levels of salinity, 0.5, 35, 70, and 140 m-equiv. NaCl/l, were imposed in culture solutions for 13 days starting when the plant had three trifoliate leaves. The highest level of salinity had a relatively greater impact on growth than the others. Differences in the dry weight of the glycines at all salinity levels were of similar proportions to those at the control level. This also applied to the laminae, stem f petiole, and roots. The data for plant nitrogen also showed these differences in growth potential at different levels of salinity. The normal capacity for growth of a cultivar seemed to be an important feature in resisting salinity.

Insight Into

Chilies are widely cultivated for their rich metabolic content, especially capsaicinoids. In our study, we determined individual sugars, organic acids, capsaicinoids, and total phenolic content in pericarp, placenta, and seeds of Capsicum annuum L., Capsicum chinense Jacq. and Capsicum baccatum L. by HPLC/MS. Dry weight varied in the cultivar ‘Cayenne’, with the first fruit having the lowest dry weight, with 4.14 g. The total sugar content and organic acid content did not vary among the fruits of all three cultivars. The cultivar ‘Cayenne’ showed differences in total phenolic and capsaicinoid content between fruits in the placenta, with the first fruit having the highest content of total phenolics (27.85 g GAE/kg DW) and total capsaicinoids (16.15 g/kg DW). Of the three cultivars studied, the cultivar ‘Habanero Orange’ showed the least variability among fruits in terms of metabolites. The content of dihydrocapsaicin, nordihydrocapsaicin, homocapsaicin, and homodihydrocapsaicin in the seeds of the second fruit was higher than that of the first fruit of the cultivar ‘Bishop Crown’. The results of our study provided significant insight into the metabolomics of individual fruits of the same chili plant. We have thus increased our understanding of how certain metabolites are distributed between fruits at different levels of the same plant and different parts of the fruit. This could be further investigated when chilies are exposed to different environmental stresses.

Brazilian semiarid region is characterized by irregular rainy periods that limits the production of forage feed for the maintenance of agricultural livestock and causes losses in the production. Despite that, semiarid region stands out in the production of forage palm, buffering the impact of drought in the area. Thus, this study aimed at analyzing the effect of different levels of salinity in irrigation water on the production of forage palm in the semiarid region. The experiment was arranged as a complete randomized block, in a 4x3 factorial arrangement and four levels of salinity (0.2, 2.0, 3.8 and 5.6 dS m-1); three cultivars (Miúda, Orelha de Elefante Mexicana and IPA-Sertânia) with 4 replications. The variables evaluated were the following: number of primary, secondary, tertiary and total cladodes, cladode biomass and estimative of threshold salinity (SL). The results showed that irrigation with saline water with an electrical conductivity of 2.0 dS m-1 negatively affected the emission of cladodes of superior orders for all forage palm cultivars. Miúda cultivar presented the best production of fresh phytomass (13.36 kg per plant) under a salinity level of 4.04 dS m-1, followed by Orelha de Elefante Mexicana (12.55 kg per plant) under a salinity level of 2.73 dS m-1 and Baiana (11.56 kg per plant) under a salinity level of 2.17dS m-1.

The growth of twenty-four varieties of three sorghum species was studied at four different salinity levels. The species were : Sorghum sudanense, two varieties ; S. verticilliflorum, one variety ; S. almum Parodi, twenty-one varieties. The salinity stress was maintained for 29 days and eventually led to breakdown of sorghums at the higher levels. Treatments were imposed when the plants were 7 cm high, at day 12. Sorghums showed a high resistance to salinity stress that compared favourably with other plant species. This is a valuable agronomic quality. There were significant differences in yield between sorghums at all salinities and these effects were in the same proportion at all levels. The distinctive feature of the study is that the nature of these differences was studied in detail, supported by chemical analysis. These results for this large number of sorghums made a general interpretation of the responses possible. At control levels the differences in yield were not due to differences in rate of growth, nor were there any differences in rate of growth between sorghums at any salinity level. Differences between sorghums, then, were a reflection of differences at control level, which appeared to be impressed on a sorghum before the treatments began.

Abstract To explore the effects of mixed irrigation on soil and crops, a pot experiment was conducted in two salinity levels of brackish water, four levels of mixed brackish-reclaimed water and freshwater irrigation as the control. The soil Na-Cl to Ca-SO4 contents changed, and activities of soil alkaline phosphatase and polyphenol oxidase changed, exhibiting a ‘V’-shaped curve with increasing the proportion of reclaimed water in the mixture. At the same brackish-reclaimed water level, there were no significant differences in alkaline phosphatase and polyphenol oxidase activities except for soil alkaline phosphatase activity decreasing significantly with the increase in salinity under brackish water irrigation. Mixed irrigation obviously improved superoxide dismutase activity but no significant influences on aboveground dry weight, underground biomass or crop physiological indexes (chlorophyll, soluble protein, malondialdehyde, peroxidase, catalase). Based on the integrated biological response index version 2 (IBRv2), the deviation of reclaimed water irrigation was the smallest, followed by 1:1 and 1:2 (3, 5 g/L brackish water salinities, respectively), with IBRv2 values of 7.94, 12.55 and 16.04. Therefore, considering the soil-crop characteristics, limited daily water amount and inadequate pipeline facilities for reclaimed water, the brackish-reclaimed water ratio should be 1:1 and 1:2 at 3, 5 g/L of brackish water, respectively.

Over the last several years, there has been increasing interest in amending the soil using cover crops, especially in desert agriculture. One cover crop of interest in the desert Coachella Valley of California is cowpea [Vigna unguiculata (L.) Walp.]. Cowpea is particularly useful in that as an excellent cover crop, fixing abundant amounts of nitrogen which can reduce fertilizer costs. However, soil salinity problems are of increasing concern in the Coachella Valley of California where the Colorado River water is a major source of irrigation water. Unfortunately, little information is available on the response of cowpea growth to salt stress. Thus, we investigated the growth response of 12 major cowpea cultivars (`CB5', `CB27', `CB46', `IT89KD-288', `IT93K-503-1', `Iron Clay', `Speckled Purple Hall', `UCR 134', `UCR 671', `UCR 730', `8517', and `7964') to increasing salinity levels. The experiment was set up as a standard Split Plot design. Seven salinity levels ranging from 2.6 to 20.1 dS·m–1 were constructed, based on Colorado River water salt composition, to have NaCl, CaCl2 and MgSO4 as the salinization salts. The osmotic potential ranged from –0.075 to –0.82 MPa. Salt stress began 7 days after planting by adding the salts into irrigating nutrient solution and ended after 5 consecutive days. The plants were harvested during flowering period for biomass measurement (53 days after planting). Data analysis using SAS analysis of variance indicated that the salinity in the range between 2.6 and 20.1 dS·m–1 significantly reduced leaf area, leaf dry weight, stem dry weight and root dry weight (P ≤ 0.05). We applied the data to a salt-tolerance model, log(Y) = a1 + a2X + a3X2, where Y represents biomass, a1, a2 and a3 are empirical constants, and X represents salinity, and found that the model accounted for 99%, 97%, 96%, 99%, and 96% of salt effect for cowpea shoot, leaf area, leaf dry weight, stem dry weight and root dry weight, respectively. We also found significant differences (P ≤ 0.05) of each biomass parameter among the 12 cultivars and obtained different sets of the empirical constants to quantitatively describe the response of each biomass parameter to salinity for individual cowpea cultivars. Since a significant salt × cultivar interaction effect (P ≤ 0.05) was found on leaf area and leaf dry weight, we concluded that salt tolerance differences exist among the tested cultivars.

This study aimed to evaluate the effect of different levels of water salinity in the development of two varieties of cactus pear (Opuntia and Nopalea). The spineless cactus is native from Mexico, but nowadays can be found in many places throughout the world. The experiment was performed at the Federal Institute of Ceará – IFCE/Campus Sobral. The experimental design was a randomized factorial 5 x 2, with five levels of salinity in the irrigation water (0.0; 5.0; 10; 15 and 20 dS m-1) and two varieties of cactus pear Small or sweet (Nopalea cochenillifera Salm-Dick) and ‘elephants ear’ (Opuntia sp) with four replications. Variables studied were: plant height (cm), length and circumference of the paddle (cm), cladode thickness (cm) fresh weight (g) and dry weight (g). The variety “elephants’ ear” is more suitable for cultivation under irrigation with saline water, because it presented a better vegetative performance compared to the small variety, being more tolerant to saline stress in different levels of salinity. The effect of the interaction between salinity and varieties showed a decrease for all variables analyzed, with reduction in forage development of palm varieties for higher salinity levels.

Rates Of Growth

The interaction of two levels of soil moisture and four levels of phosphorus on the development of Macroptilium atropurpureurn was studied for 18 harvests at 2-day intervals beginning on day 29 after sowing. Variates studied were fresh weight. dry weight, nitrogen and phosphorus contents for the laminae. stem plus petioles, root and nodules. The responses to treatment of these variates were shown by preliminary analyses of variance to contain complex patterns of interaction. The important facets of these interactions were then appraised by an extension of the usual univariate methods and the overall pattern of the interaction was delineated by a classificatory analysis. On the basis of the 14 attributes studied, there were six groups of responses to treatment. The lowest of these groups corresponded to failure to grow at low levels of phosphorus. The next group represented the response of nodules to treatment. Subsequent groups represented higher growth potential following efficient functioning of the nodules. Effects on nodulation were thus primary to subsequent patterns of plant development. Water stress greatly impaired both plant and nodule development, particularly at the higher two levels of phosphorus, whereas active growth occurred in normally watered plants. At these two phosphorus levels the effect of water stress was on development rather than on chemical composition, there being large absolute but small relative effects on chemical data. The lower levels of phosphorus supply contrasted with the two higher levels in having much lower rates of growth and of water loss.

Forage palm (Cactaceae) is considered an important resource in the semiarid region of Brazil. This study aimed to analyze the effect of different levels of salinity in irrigation water on the growth of three forage palm cultivars. The study was conducted at the Federal University of Campina Grande (7° 12’ 52.6’’ S; 35° 54’ 22.3’’ W) in 120 L pots open to the sky. The experiment was a complete randomized block, with four replications and a 4 × 3 factorial arrangement. The treatments consisted of four levels of salinity in irrigation water with electrical conductivity of 0.2, 2.0, 3.8, and 5.6 dS m–1, and three forage palm cultivars: Miúda or Doce (Nopalea cochenillifera Salm Dyck), Orelha de Elefante (Opuntia stricta), and Baiana or IPA–Sertânia (Nopalea cochenillifera Salm Dyck). At 150 days after treatments, it was evaluated: length, width and perimeter of primary and secondary cladodes and total number of cladodes. Variance analysis was performed using an F-test (p < 0.05); significant effects were subjected to quadratic regression analysis for the quantitative variable, and the Tukey test (p < 0.05) for the qualitative variable. Salinity levels in irrigation water did not affect the growth variables. There was a significant difference in the growth of forage palm as a function of its cultivar. The Baiana cultivar showed the highest vegetative growth of length and perimeter of primary and secondary cladodes, while Miúda and Orelha de Elefante presented the greatest cladode numbers for plant and cladode widths, respectively.
