Nine clones of Solanum tuberosum L. cv. Kennebec from sources in Victoria, South Australia and Tasmania, and the commercially grown clone, clone 1, which was imported from Vancouver, were multiplied from pathogen-tested seed and compared in 3 Victorian potato districts during 2 seasons. Haulm appearance of the 10 clones was similar. Tubers of clones 2 and 9 had a more desirable elliptical shape with shallow eyes than clones 1, 7, 8, 11 and 13. Clone 7 produced significantly (P<0.05) less total yield than the highest yielding clone at 3 sites. Compared with the other clones, clones 2 and 7 yielded significantly (P<0.05) less oversize (>450 g) and medium (100-450 g) tubers and significantly (P<0.05) higher yields of small (<100 g) tubers at several sites. Clone 1 produced a much higher proportion (5.7%) of total yield as oversize tubers than clones 2 (1.6%) and 7 (0.8%). Clones 2 and 7 produced a significantly higher (P<.05) number of tubers per plant than all other clones at the 3 sites. Averaged over these 3 sites, clones 2 (and 7) produced 6.2 (6.8) tubers per plant and the other clones were in the range 4.5-5.0. No consistent differences in specific gravity or crisp colour were observed between the clones. Clone 2 was selected as being best suited for the crisp processing industry because of its even shape, high number of tubers per plant and low yield of oversize tubers, while maintaining high yields and good specific gravity and crisp colour. Our results show that differences exist in total and size grade yield and tuber number and appearance between clones of a cultivar. They further highlight the importance of selection work to maintain desirable characteristics of established cultivars and to remove mutants with undesirable characteristics.

Main Effects

Five field experiments were conducted over 3 years in the Mt Lofty Ranges (4 sites) and the Upper South East (1 site) to examine the significance of main effects and interactions between nitrogen (N, up to 360 kg N/ha), phosphorus (P, up to 320 kg P/ha), and potassium (K, up to 480 kg K/ha) on total yield, yield of 80-350 g size grade, specific gravity, crisp colour, and chemical composition of tubers of potato cv. Kennebec. There were significant (P<0.05) main effects of increasing rates of applied N on total tuber yield and yield of 80-350 g tubers at 2 of the 5 experimental sites; the effect of applied P was significant at 3 sites, and applied K also at 3 sites. Application of N, P, and K increased total tuber yield by 13-432%, 19-145%, and 19-89%, respectively, at responsive sites. Increases in the yield of 80-350 g tubers were similar to those for total yield. There were significant first-order interactions (N x K, N x P, K x P) at 2 sites. The interactions were (i) response to the application of 1 nutrient limited by suboptimal rates of another; and (ii) yield depression, due to high rates of 1 or more nutrients. Nitrogen and P increased specific gravity at only 1 of the sites where they were applied. Potassium increased specific gravity at 1 site but decreased it at another. There were significant N x K, N x P, and K x P interactions at 2 sites. Vascular ring colour index (CI) and medulla CI were significantly (P<0.05) affected by rates of applied N, P, and K at 1, 3, and 4 experimental sites, respectively. Application of K (up to 480 kg K/ha) decreased vascular ring CI and medulla CI. Application of P increased the colour indices; for example, increasing the rate of P from nil to 160 kg/ha increased mean (� s.e.) vascular ring CI from 51 � 18 to 117 � 17. No interactions between N, P, and K in their effects on medulla CI were significant. For vascular ring CI, significant first-order interactions (K x N, K x P) were observed at 2 sites, at which application of N and P at nil K significantly increased vascular ring CI. At 240 or 480 kg K/ha, there was no change. Significant (P<0.001) curvilinear relationships were found between specific gravity and the concentrations of N, P, and K in the stem-end region of tubers; the coefficients of determination (r2) were 0.27, 0.62, and 0.76, respectively. For the combined medulla CI and vascular ring CI data, the corresponding values were 0.19 (P<0.001), 0.29 (P<0.001), and 0.05 (n.s.), respectively.

The eastern sub-Himalayan plain of India is a popular potato growing belt in which vast scope exists to introduce processing grade cultivars. The selection and introduction of a better quality processing grade cultivar in this region may pave the way for the processing industries. Keeping these in the backdrop, this study was conducted at Instructional Farm of Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India under eastern sub-Himalayan plains during winter seasons of 2016–17 and 2017–18 in which seven processing type potato cultivars (Kufri Chipsona-1, Kufri Chipsona-3, Kufri Chipsona-4, Kufri Frysona, Kufri Himsona, Kufri Surya and Kufri Chandramukhi) were evaluated in terms of different quality parameters pre-requisite for chips processing viz., dry matter content, specific gravity, starch content, chips colour score, crispiness and hardness of chips through randomised complete block design (RCBD). The study revealed wide variation in all quality parameters amongst the cultivars. Cultivar ‘Kufri Frysona’ showed the highest specific gravity (1.121) as well as dry matter content (23.35%) followed by ‘Kufri Chipsona-3’. The cultivar ‘Kufri Frysona’ showed the highest starch content (28.52%) too. Chips prepared from ‘Kufri Chipsona-1’ were recorded to be crispier with a relatively lower value of deformation before the first break and less hardness value. All processing type potato cultivar reflected the chips colour score <3 (evaluated, based on 1–10 scale, 10 being the darkest and least desirable) though ‘Kufri Frysona’ had the lowest chips colour score (1.50) signifying its superiority for the region. ‘Kufri Frysona’ cultivation could be recommended in this agro-climatic region particularly for chips manufacturing potato industries.

Sulfonates are well-known substances with a variety of applications, e.g. as surfactants. On the other hand, bis(sulfonates) bearing hydroxyl or keto group(s) in between the sulfonate groups can be used with or without further modification as starting materials for the preparation of new type of molecules capable to form either complexes or in general supramolecular structures. The synthesis of three hydroxyl-bearing bis(sulfonates), 2-hydroxypropane-1,3-bis(sodium sulfonate) 4, DL-2,3-dihydroxybutane-1,4-bis(sodium sulfonate) 8, and sodium 2,3,4-trihydroxy-1-sulfonate 7 (as by-product) via the Strecker sulfonation are described. Interestingly, under similar conditions, sulfonation of 1,4-dibromo-2,3-butanedione 9 was found to be very complicated and no pure product could be isolated, despite previously reported results on sulfonation of α-halogenated ketones in high yields. There are indications that SO3 2 -  attacks at the carbonyl carbon of 9 followed by rearrangement and expulsion of SO4 2 - . 1,4-dibromo-2,3-butanedione 9, bearing two keto groups next to methylene groups, can potentially exist as enols or in the case of its solution in hydroxylic solvents in the form of hemiketals or geminal diols. This behavior of 9 when is dissolved in CDCl3, CD3OD and D2O was studied by means of UV-Vis, 1H and 13C NMR and the nature of the adducts formed was elucidated.

A fast and convenient protocol for the synthesis of novel spiro[dihydropyridine-oxindole] derivatives in satisfactory yields was developed by the three-component reactions of arylamine, isatin and cyclopentane-1,3-dione in acetic acid at room temperature. On the other hand the condensation of isatin with two equivalents of cyclopentane-1,3-dione gave 3,3-bis(2-hydroxy-5-oxo-cyclopent-1-enyl)oxindole in high yields. The reaction mechanism and substrate scope of this novel reaction is briefly discussed.

In a paper “ On the Expansion by Heat of Water and Mercury” *, a method of determining the expansion of bodies is described, by which good results can be obtained with comparatively small quantities of the substances to be experimented with. This method, that of weighing the body in water at different temperatures, has been employed for the present research. The results obtained are given in the following Tables:— From the above the following conclusion is drawn-namely, that just as it may be said that the specific gravity of an alloy is approximately equal to the mean specific gravities of the component metals , so also from the foregoing we may deduce that the volume which an alloy will occupy at any temperature between 0° and 100° is approximately equal to the mean of the volumes o f the component metals at the same temperature, or, in the other words, the cubical or linear coefficients o f expansion by heat of an alloy between 0° and 100° are approximately equal to the mean of the cubical or linear coefficients of expansion by heat o f the component metals .

Abstract As antioxidant enzymes, catalase (CAT) protects organisms from oxidative stress via the production of reactive oxygen species (ROS). These enzymes play important roles in diverse biological processes. However, little is known about the CAT genes in potato plants despite its important economical rank of this crop in the world. Yet, abiotic and biotic stresses severely hinder growth and development of the plants which affects the production and quality of the crop. To define the possible roles of CAT genes under various stresses, a genome-wide analysis of CAT gene family has been performed in potato plant.In this study, the StCAT gene’s structure, secondary and 3D protein structure, physicochemical properties, synteny analysis, phylogenetic tree and also expression profiling under various developmental and environmental cues were predicted using bioinformatics tools. The expression analysis by RT-PCR was performed using commercial potato cultivar. Three genes encoding StCAT that code for three proteins each of size 492 aa, interrupted by seven introns have been identified in potatoes. StCAT proteins were found to be localized in the peroxisome which is judged as the main H2O2 cell production site during different processes. Many regulating cis-elements related to stress responses and plant hormones signaling were found in the promoter sequence of each gene. The analysis of motifs and phylogenetic trees showed that StCAT are closer to their homologous in S. lycopersicum and share a 41% – 95% identity with other plants’ CATs. Expression profiling revealed that StCAT1 is the constitutively expressive member; while StCAT2 and StCAT3 are the stress-responsive members.

Abstract This study encompasses investigation of treatment of pistachio processing industry wastewaters in a batch reactor under aerobic conditions, calculation of kinetic parameters and comparison of different inhibition models. The mixed microorganism culture used in the study was adapted to pistachio processing industry wastewaters for nearly one month and then concentrations from 50-1000 mg L− 1 of pistachio processing industry wastewaters were added to the medium and treatment was investigated in batch experiments. The Andrews, Han-Levenspiel, Luong and Aiba biokinetic equations were chosen for the correlations between the concentration of pistachio processing industry wastewaters and specific growth rates, and the kinetic parameters in these biokinetic equations were calculated. The µmax, Ks and Ki parameters, included in the Aiba biokinetic equation providing best fit among the other equations, had values calculated as 0.25 h− 1, 19 mg L− 1, and 516 mg L− 1, respectively.

Rhizoctonia disease (black scurf of tubers and stem canker) of potato (Solanum tuberosum L.) caused by Rhizoctonia solani Kühn was first recorded in South Africa in 1918 (3). Although the sclerotial form on tubers is one of the most common potato diseases in the country, it is not known which anastomosis groups (AGs) of R. solani are involved. Between 1999 and 2001, R. solani was isolated from 28 plant and 56 soil samples collected in 7 (Eastern Free State, Gauteng, KwaZulu-Natal, Limpopo, Mpumalanga, Northern Cape, and Sandveld) of the 14 potato-production regions of South Africa and screened for hyphal anastomosis with tester strains of R. solani AG-1 to AG-10 according to Carling et al. (1). Of the 411 isolates from tubers with black scurf symptoms, 408 were AG-3 and three were AG-5. Symptomless tubers yielded two AG-3 isolates and three AG-5 isolates. Of 39 isolates from symptomatic stems and roots, 32 were AG-3, five were AG-4, and two were AG-5. Of the 127 isolates obtained from soil, 86, 28, 7, 3, and 3 were AG-3, AG-4, AG-5, AG-7, and AG-8, respectively. More than one AG was isolated from five of the seven regions. Virulence of 40 isolates representative of the above AGs was determined in triplicate on sprouts growing from seed tubers of potato cultivar Up-to-Date in a sand/soil mixture as described by Carling and Leiner (2) but using cultures grown in cornmeal/sand instead of colonized agar disks as inoculum. Damage to sprouts (lesions, girdling, and death) was assessed after 28 days at 16 to 28°C according to the 0 to 4 rating scale (2). Chi-square analysis of the data indicated that AG-3 was the most virulent, with isolates from sclerotia on tubers and lesions on stems more aggressive than those from symptomless tubers or soil. AG-4 and AG-5 caused significantly less disease than AG-3, but none of the AG-7 and AG-8 isolates showed any virulence to potato sprouts. References: (1) D. E. Carling et al.
