Variation in floral organs in wild populations of Brassica rapa L.

摘要: In the hermaphroditic plants, floral morphological traits can significantly affect reproductive system by favouring deposit of self or cross pollen. Brassica species, self-incompatibility mechanism is undoubtedly main cause their allogamy; however, organs variation modulate reinforce pollination level plants. this study, we investigated among wild populations rapa L. from Algeria. We estimated 20 traits, including sepals, petals, pistil, stamens and nectaries as well ovules production. Floral parameters were measured using stereomicroscope. Each flower's ovule number stigma-anther separation also quantified under dissecting microscope. found that all flower vary individuals, especially stigma surface, nectary surface separation. These three have a coefficient greater than 18,9%. Moreover, individual different according to populations. results suggest morphology may efficiency consequence seed production in B. but with contributions traits.
