Morphological Differentiation of Flower Bud in Amygdalus Ledebouriana Schleche

In order to provide a theoretical basis for domestication,cultivation,development and utilization of almond,morphological differentiation of flower bud in wild almond in Xinjiang was observed and researched by paraffin section method. The results indicated that morphological differentiation of flower bud could be divided into 5 stages: initial flower bud differentiation,sepal differentiation,petal differentiation,stamen differentiation and pistil differentiation. Morphologic differentiation of flower bud started from the middle of June,and the whole process was concentrated from early July to early September. The differentiation stages appeared overlapping. It need take 90～100 days to finish morphological differentiation of flower bud.
