Determination of low temperature tolerances of some tomato genotypes
Öz
Low temperature is one of the most important environmental stress factors. In this study, 9 of pure lines at the F9 stage which belonged to Batı Akdeniz Agricultural Research Institute (BATEM) were used as a plant material to determine the lines tolerant to low temperatures. Low temperature applications were carried out in vegetative and generative stages. Solanum hirsutum (LA 1777) and 2 commercial varieties; (Cigdem F1 and Anit F1) used as tolerant genotypes (Control). The tomato seeds were germinated and grown in a mixture of peat and perlite (1:1 v/v). When the seedlings reached two true leaf stages, they were taken to the temperature, humidity and light controlled growth chamber for low temperature applications in vegetative test. At the vegetative test, plants were exposed to the 5±1°C, at light intensity 350 μmol m-2 sec-1 for five days. In the generative tests, the genotypes were selfed in the growth chamber with 5±1°C and 180 μmol m-2 sec-1 of light intensity and taken to the greenhouse for fruit set after three days. As a result, it was determined that genotypes 5 and 6 were found as tolerant to the low temperatures in terms of dry matter production and seed amount both in vegetative and generative stages.
