The effect of increasing concentrations of Al2(SO4)3 in situ on the content of starch, sugars and activity behaviour of enzymes related to their metabolism were studied in growing seedlings of two rice cvs. Malviya- 36 and Pant-12 in sand cultures. Al2(SO4)3 levels of 80 and 160 μM in the growth medium caused an increase in the contents of starch, total sugars as well as reducing sugars in roots as well as shoots of the rice seedlings during a 5–20 days growth period. The activities of the enzymes of starch hydrolysis α-amylase, β-amylase and starch phosphorylase declined in Al-exposed seedlings, whereas the activities of sucrose hydrolyzing enzymes sucrose synthase and acid invertase increased in the seedlings due to Al3+ treatment. The enzyme of sucrose synthesis, sucrose phosphate synthase showed decreased activity in Al3+ treated seedlings compared to controls. Results suggest that Al3+ toxicity in rice seedlings impairs the metabolism of starch and sugars and favours the accumulation of hexoses by enhancing the activities of sucrose hydrolyzing enzymes.

Induction of nitrate reductase (NR) activity in coralloid roots of Cycas revoluta was observed after 8 h incubation in 0.02 M KNO3. Other plants growing near Cycas showed a higher level of NR immediately when incubated in KNO3. In contrast to NR, intact coralloid roots showed very high nitrogenase activity (~1.2 to 1.6 µmol C2H4 g fresh wt-1 h-1) under both light and dark conditions as compared to transverse sections of roots. Localization of NR and nitrogenase was tested in coralloid roots using different sets of roots and also in the endophyte. Our results showed that NR activity was mainly due to the endophyte (Anabaena cycadeae); coralloid roots lacked it, as no NR activity was observed in chloramphenicol-treated intact root samples.

Early postharvest decay of tomato is a major concern of research. Several pre and postharvest efforts have been suggested to improve the shelf life of commercially grown tomatoes. However, finding the cultivars with increased shelf life is not yet achieved. Our study focused on the characterization of two color mutants [dg (BCT-115) and ogc (BCT-119)], one ripening mutant [rin (BCT-111)], and seven normal tomato genotypes [Berika (high lycopene) Punjab, Chhuhara, FEB-2, BCT-53, Patharkutchi, CLN-B, and CLN-R] using different physicochemical and subjective variables to acknowledge the storage potential at 25 ± 1 C and RH 80–82 %. There were significant variations in storage life among all tomato genotypes. Except ogc, the mutant (dg and rin) tomatoes showed longer shelf life in relation to normal tomatoes. Based on their storability, the genotypes were classified into three groups i.e. shelf life less than 15 days [CLN-B, BCT-53, CLN-R, and BCT-119 (ogc)], 15–18 days [FEB-2, Punjab Chhuhara, Patharkutchi, and Berika] and more than 18 days [BCT-115 (dg) and BCT-111 (rin)]. We suggest that selecting the genotype/cultivar having longer shelf life during formulation of breeding strategy could improve the marketability of tomato fruits for relatively longer period.
