Abstract

In order to study seed GERMINATION responses of PURSLANE (Portulaca oleracea L.) to temperature regimes, an experiment was carried out in a completely randomized design with five replications and seventeen levels of temperature (0, 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 37, 40, 45, 50, 51oC). The results showed that increasing temperature significantly increased percentage and rate of GERMINATION, also length and dry weight of radicle and plumule, ratio of root to shoot length and seedling vigor index while decreased the mean GERMINATION time. Highest GERMINATION properties observed in the range of 10-40oC and lowest GERMINATION occurred at 5oC. Highest GERMINATION rate was in 35 degree but there was not significant different in the range of 20-40 degree treatment. Therefore, base temperature for PURSLANE GERMINATION estimated at 5, optimum temperature in range of 10-40 and maximum temperature equal to 50oC, repectively. This extended temperature range for GERMINATION and the ability to germinate rapidly suggest the high potential of PURSLANE to establish in most arid and semi arid areas of Iran as a weed, vegetable as well as medicinal plant.
