The influence of salt stress on foliar water content leaves of some tomato cultivars from N-E Romania

Abstract

Water is an important factor for the distribution of plant species on Earth, under stress leaves are the organs which are observed first symptoms. The research was conducted under greenhouse condition. The biological material was represented by ten local tomatoes populations collected from areas with saline soils from Moldavia region and compared with commercial type salt-tolerant tomato. Tomato genotypes in the study were subjected to salt stress for a period of 30 days is constantly wetted with saline solution to a concentration of 100 mM and 200 mM. There have been a number of quantitative investigations in the foliar ascertaining the fact that the genotypes subjected to salt stress is a reduction in the content of free water and to increase the amount of water bound thereby increasing the capacity of the biological tolerance of such local populations of tomatoes.
