Phenolic Compounds Enhanced Low Temperature Stress Tolerance in Tomato (Solanum lycopersicum L.)

performed the experiment, statistical analysis, the protocol the first the DSK, NK and KS designed and managed the analyses of the study. the ABSTRACT Low temperature stress their effect on morphological, yield and quality traits. Based on two year study, its observed that low temperature significantly reduces the growth traits (plant height, number of branches, number of leaves, shoot and root length, and total biomass of plant), yield attributes (days to 50% flowering, fruit weight and fruit yield) and quality parameter (total soluble solid), however there was an increase in titrable acidity and ascorbic acid. On the hand, application of phenolic compounds significantly enhanced the growth, yield and TSS, while, decreased titrable acidity and ascorbic acid under stress. Two years study has confirmed that phenolic compounds protect plants against low temperature stress and enhanced production of tomato with an increase in the yield and quality contributions attributes. Among the treatments, SA (1.0 mM) was found as most effective to enhance low temperature stress tolerance in tomato.
