Abstract

Physiology of germination in Bauhinia: involvement of seed coat in inhibition of germination in B. racemosa Lam. seeds.

Abstract

In Uttar Pradesh, India, seeds of Bauhinia racemosa exhibited coat-imposed dormancy with only 38% germination after 16 days. Improvement in the germinability of seeds was accomplished by soaking seeds in hot water and through mechanical scarification, resulting in 68 and 98% germination, respectively. These treatments also considerably reduced germination time. Data indicated that the seed coat did not act as a mechanical restraint to embryo growth but did prevent water entry to the seed. Therefore, B. racemosa seeds should be sown after mechanical scarification for quick and uniform germination. Authors' summary.
