油橄榄花芽分化的形态解剖学特征观测

Observation on Morphological and Anatomical Characteristics of the Flower Bud Differentiation on Olive

采用石蜡切片法对不同品种油橄榄花芽形态分化过程进行形态解剖,并用显微镜进行观察。结果表明：1）油橄榄花芽在云南省楚雄州永仁县的形态分化从1月下旬开始,2月上中旬芽萌动,不同品种的油橄榄花期会有10-15 d的差异,阿斯和鄂植的花期稍长,豆果和柯基的花期稍短;2）花芽各器官分化时期相对集中,各个不同的花芽器官按先后顺序分化,其分化时间互有交错重叠;3）形态分化初期时间较长,从开始到分化高峰约2周,在此之后,各器官的分化期较短。

Using the paraffin section method,morphological differentiation process of different varieties of Olea europaea flower bud was dissected and observed by microscope. Results showed that：（ 1） Flower bud morphological differentiation of Olea europaea in Chuxiong Yongren County started from late January,and germinated in the middle of February. Usually 10- 15 days difference of florescence for varieties of Olea europaea. Aspen and Hubei plant flowering were slightly longer,beans,fruit,and Corgi flowering slightly shorter;（ 2） Flower organs differentiation period were relatively concentrated,the differentiation of different floral organs was followed the sequence of differentiation,the differentiation time were overlapping;（ 3） Early morphological differentiation stage was longer,the differentiation from beginning to peak was about two weeks,after that,each organ differentiation period was shorter.
