Seed dormancy in Cucumis sativus L.

A. S. Halimathul Saadiah

Abstract

Seed dormancy in cucumber is a varietal characteristic. Two of the varieties tested, MTi 1 and MTi 2, were found to have dormancy period of 70-80 and 60-70 days, respectively. Germination in variety Bukit Mertajam was either close to or above 80% immediately after harvest. KNO₃ at a concentration of 0.1% increased germination percentage but did not completely overcome dormancy. A slight increase in germination was also obtained in the presence of light and with the partial removal of the seedcoat.
