观察研究了喀什地区 4个巴旦杏主栽品种的开花物候期、开花习性、花及花粉的形态特征等内容 ,结果表明 :巴旦杏花期始于 3月下旬或 4月上旬 ,花期持续约 1 0～ 2 0 d,4个主栽品种花期相遇 ;品种间花的形态存在差异 ,早开的花花质较好 ,晚开的花畸形花百分率较高 ;供试品种的花粉粒在扫描电镜下存在微形态上的差异。
Flowering phenology and some related characteristics,morphology of flowers and pollens of 4 almond cultivars in Karshi Prefacture were studied and the following conclusions were drawn:The blooming period of the cultivars started at late March or early April,lasting for about 10 to 20 days,and the blooming period of these cultivars was over lapped one another;There were some differences in morphological structure of flowers among the cultivars,and was a higher percentage of abnormal flowers among later bloomed ones;There were some differences of micros morphology in pollens by Scanning Election Microscope among the tested cultivars.
