Morphogenesis of Buds of the Rare and Disappearing Plant Alnus Subcordata C.A. Mey

ABSTRACT

We investigated that the morphogenesis of the bud of Alnus subcordata C.A.Mey. which belongs to 3^rd time and is one of the rare plants to determine the evolution for plant ontogenesis. Formation of meristhematic bud of the plant required long time, so the study was divided into three stages that was totally duration 33–34 months. Although preformation of generative organs was occurred during winter development of the bud was continuously with exception a few short dormancy. It was revealed that the Alnus was everygreen in 3^rd time and in very wide-area distributed over world in the present time. Besides it was determined that Alnus, was relict taxon, was capable of a very wide adaptation. In our results, flowering time of Alnus subcordata C.A.Mey. was on August.
