Effect of water stress on selected physiological characteristics of tomatoes

Popis výsledku v původním jazyce

This work presents the results of a field experiment with tomato cv. Proton grown under water stress conditions and under well irrigated conditions. At the same time, the effects of Pentakeep supporting agent (consisting of aminolevulinic acid) was studied. The following characteristics of plant physiology were studied -- specific leaf area (SLA), leaf water content (LWC) and leaf proline concentration. The obtained results show a significant decrease in SLA during plant vegetation (from 190 to 165 cm --2.g--1). A decrease was also found under water stress treatment (163 cm--2.g--1), in contrast to the well watered control (184 cm--2.g). LWC values ranged from 81 to 87 % in both seasons. A significantly important decrease of LWC was found in the stressed variant. Pentakeep application did not affect either SLA or LWC characteristics. The level of proline in tomato leaves varied from 0.6 to 1.5 umol.g--1. The highly significant effect of water conditions resulted in the increase of prol
