Effect of low temperature storage on fruit physiology and carbohydrate accumulation in tomato ripening-inhibited mutants

Chilling-sensitive fruits often produce a burst of ethylene when reconditioned at ambient temperature after cold storage. This has led some researchers to propose that chilling injury (CI) may be induced by post-chilling ethylene production. To test this hypothesis, we examined two tomato (Solanum lycopersicon L.) mutants, non-ripening (nor) and ripening-inhibitor (rin), that do not produce climacteric ethylene, after...

Extracts of Jatropha curcas L. exhibit significant insecticidal and grain protectant effects against maize weevil, Sitophilus zeamais (Coleoptera: Curculionidae)

Phytochemical composition of leaf extracts as well as biological effects of juice, leaf extracts and seed oil of Jatropha curcas against Sitophilus zeamis were examined. The study also investigated the inhibition of oviposition, progeny production and grain damage, insecticidal effects and mammalian toxicity of the extracts. Compared to other phytochemicals, the concentration of saponin and cardiac glycoside were higher...
