【摘要】 野生巴旦杏种子营养与医学药用价值极高,是一类重要的遗传种质资源。不过最近几年由于人为因素和环境因素的变化,野生巴旦杏分布面积不断减少。对野巴旦杏4个不同类型的果实和种子特性进行观测,根据单因素方差分析结果得出,果核长、果核厚、果核重、果仁重、果壳重等6项指标差异达到显著水平,而果核宽等2项指标差异达到极显著水平。基于8个特性指标测量值,对野巴旦杏形态类似程度进行聚类分析,结果有喙圆、无喙圆、无喙扁为一类,有喙扁单独一类。更多还原

【Abstract】 The characteristics of seed morphology and seed variation of wild almond seeds were revealed. Different morphological seed survey and statistical analysis methods were used to observe the fruit and seed morphology of 4 different morphologies. Single factor analysis of variance showed that form between the stone of the fruit is long,thick stone,stone of the fruit,nuts,fruit shell weight,seed length and seed width ratio(GHC,GHH,GHZ,GRZ GKZ,GHC/GHK)significant difference,the stone of the fruit and nuts weight and stone of the fruit weight ratio(GHK,GRZ/GHZ)showed extremely significant. The four morphological features of cluster analysis are beaks and beaks,which have beaks and beaks,which have beaks and beaks,and have no beaks. It is indicated that the shape of beaks and beaks is relatively close,and the beaks and beaks are relatively close. It has beak circle and non-beaked flat and has the appearance feature of beak flat appearance is relatively close,and has the appearance characteristic of beaked flat is far. The seed morphology of wild Amygdalus Ledebouriana is rich in variation,and it should pay attention to the difference of environment in the breeding of its excellent provenance,so as to exploit and conserve resources.更多还原
