CALLUS INDUCTION IN OAT (Avena saliva L.) GENOTYPES
Abstract
Nine oat genotypes were cultivated in vitro in order to estim ate callus initiation capability. 7Wo experiments were realized, first the culture medium were tested with different hormones dosages and the genotypes for variability, atter, the cultivars were exposed to the best medium. The immature embryo were measured to test the adequate size to calogenese and the data was similar to literature. All genotypes produced cali, and variability was observed among them concerning this caracter. Almost all cali revealed organogenic and embryogenic structures. The A and B medium (with 2 and 4 mg/1 2,4 D respectivily) were adcquatcd to cali induction in oat.
