Type: article
Abstract: Cultivated plants are often exposed to different types of environmental stress, which limits their development and productivity.High temperature stress induces considerable changes in the biochemistry and physiology of plants.The aim of the present investigation was to evaluate the physiological response of some tomato genotypes to a high temperature stress.Experiments were carried out during the stress period and after its elimination.Valuation of the tolerance of plants was carried out by means of a physiological test.It was observed that the high temperature stress has an inhibitory effect on the physiological state of tomato plants.The degree of its inhibited action was individual, depending on the genotype.KEY WORDS: Lycopersicon esculentum L., high temperature stress, physiological test, leaf gas-exchange, photosynthetic pigments РЕЗЮМЕ Културните растения често са подложени на различни видове стрес от околната среда, което ограничава тяхното развитие и продуктивност.Високотемпературният стрес предизвиква значителни изменения в биохимията и физиологията на растенията.Целта на настоящата разработка е да даде оценка на физиологичния отговор на някои доматени генотипове на високотемпературния стрес.Опитите бяха направени по време на действието на стреса, както и след неговото отстраняване.Оценката на издръжливостта на растенията беше извършена с помощта на физиологичен тест.
