REDUCING THERMO STRESS EFFECTS ON TOMATO CROP (Lycopersicon esculentum, Mill) BY USING PIGEON PEA AS SHADING PLANTS AND FOLIAR APPLICATION WITH SOME STIMULATIVE SUBSTANCES UNDER HIGH TEMPERATURE OF SUMMER SEASON.
High temperature is a serious environmental factor which induce heat stress causing bad effect on growth, flowering and fruiting stages of tomato plants during summer season. For this purpose, the adverse effects of heat stress on tomato growing during summer season can be mitigated by some agro-techniques, i.e., shading plants and foliar application by specific stimulatory substances. Therefore, Two field experiments were carried out at EL-Baramon Research Station, Dakahlia Governorate, Egypt, to study the effect of shading by using pigeon pea plantation and foliar applications with calcium )2000 mg/L), boron (50 mg/L), vitamin E (150 mg/L) and selenium + vitamin E (50+150 mg/L) towards better thermal tolerances and higher productivity of tomato (Lycopersicon esculentum, Mill) cv Alisa Hybrid F1 during summer seasons of 2010 and 2011. The results revealed that both shading and aforementioned substances had ameliorative effects against the adverse condition on tomato plants, compared with control, which were reflected by enhancing vegetative growth characters (plant height, number of branches and leaves/plant and fresh and dry weight/plant), flowering aspects (number of flowers and clusters/plant, fruit set percent, number of fruits/plant and fruit weight), fruit quality (firmness, TSS, ascorbic acid BER and sunscald) and marketable fruit yield and yield attributes. However, the most effective treatments were foliar application by boron and calcium mixture and/or individual and shading 2 (growing pigeon pea plants on 100cm apart) in which attained the highest marketable fruit yield, by 44.95, 38.7, 34.21, 26.82, 25.75, 17.99, 15.13 and 14.39%, over the control, as for B and Ca mixture, B, shade 2, Se and VE mixture, Ca, shade 1, shade 3 and VE respectively, and best performance in the two studied seasons. By contrast, the adverse action of high temperature resulted in reducing growth and reproductive parameters of tomato plants, and increased fruit disorders, blossom end rot and sunscald injuries, (untreated control) in both seasons.
