Abstract
Temperature is one of the most important factors influencing fruit and seed formation. Low or high temperature during reproductive stage of many crops causes sterility of pollen grains and reduced yield. Effects of different temperatures (20, 25, 30, 35, 40 and 45 °C) were studied on pollen germination and pollen tube growth of two melon cultivars (Green Tile and Chah Paliz). Field experiment was conducted during the summer season in Torbat-e-Jam. Male flowers of two native Iranian melon cultivars were collected and transported to the laboratory. Pollen grains were placed in medium culture in Petri dishes containing MS medium. The experiment was arranged in a completely randomized design with 3 replications. Maximum germination was obtained at 30 °C. Maximum pollen tube growth was recorded at 35 °C. The findings of this study showed, in vigour viability of pollens were decreased high temperatures and male reproduction organs at melon were sensitive to heat stress.
