The article presents data on the reaction of different varieties and tomato lines of different ecological and geographical origin to stressful temperatures (35, 38, 42°C). The parameters of the effect estimation were the length of the embryonic root and the stalk length. Was revealed a significant differentiation of the reaction of tomato genotypes to the specified temperature. A strong inhibition under the action of 35°C was detected only in the L11 line (–27,1), and at 380°C in L310 (–15,0%). Under the influence of a temperature of 42°C, pronounced suppression of root growth occurred in the majority of the studied genotypes. Under the influence of stressful temperatures, the genotypes showed a rather differentiated reaction and a high variability of the trait stalk length: in 19 cases inhibition occurred –5,5%...–31,1%), and in 11 cases – stalk growth was stimulated (+3,3%...+32,2%). Strong inhibition under the action of 38°C was noted in the genotypes Mariuca (–28,4%), L11 (–22,8%); 450C – Pontina (–25,0%), Flacara (–23,9%), Florina (–25,8%), Mariuca (–31,1%), L11 (–25,6), L71 (–6,5%). As a result of cluster analysis, Flacara and Mary Gratefully genotypes were identified with the least sensitivity to the indicated stress temperatures, which is very important for their inclusion in breeding programs as potential donors of resistance to heat. |
