Effects of different temperatures and duration on germination of caper (Capparis ovata) seeds

摘要

Caper seed has poor germination because of the seed coat dormancy. Germination of caper seeds are complex traits affected by a wide range of internal and environmental influences. The effects of temperature preconditioning and period on germination of Capparis ovata were examined. Experiments were conducted in order to investigate germination behaviour of caper seeds subjected to different temperature and duration. The experiment revealed that the different temperature treatments were effective on mean germination percentage. The highest mean germination were obtained at 0℃ 29.52% and 10℃ with 27.17% and the lowest mean germination were obtained at control seeds with 8.39 %. Dry heat treatments effected germination rate, but it was not enough for removing germination obstacle of caper seed completely.
