Yield and physiological parameters of Siriana F1 under conventional and unconventional stimulants

Abstract

Tomato (Lycopersicon esculentum Mill.) is a leading vegetable crop, in terms of global cultivation (open field and protected area) and consumption. The chemical nutrients of plants serve as critical factors that determine the plant growth and vigour, also the crop yield. In addition, these nutrients play aparticular role in contributing to the survival of crop plants under environmental stress conditions. Under climatic or nutritional stress, the productivity is affected in a percentage that range between 45-70%. In this study, the influence of unconventional and conventional stimulants was evaluated for Siriana F1 in term of physiological parameters and yield. In order to achieve this, at UASVM Iasi was carried out an experiment on a tomato crop from the Siriana F1 hybrid, where six treatments were tested compared to a control version.The highest values of the analyzed physiological parameters were recorded under treatment of Au -citrate C; for the total pigments this variant had the lowest value, respectively 14.9 CCI.
