Tomato plants of the heat-tolerant cultivar Hazera 3042, were grown in two temperature-controlled greenhouses. One greenhouse (control) was configured for optimal grown with daytime temperature of 25 degrees C and nighttime temperature of 18 degrees C. The other greenhouse (treatment) was set to 32 degrees C daytime temperature and 26 degrees C nighttime temperature.  Several times during Sept and October of 2013, pollen samples were collected from plants in each greenhouse. Each collection consisted of one batch of pollen harvested from several plants in the control group and another batch harvested from several plants in the treatment group.
