黑龙江省家植五味子果实发育与产量相关分析

对小兴安岭地区家植五味子结实物候、果实发育特征进行观测,并对穗长与穗重进行相关性分析;五味子果粒生长有两次高峰期,第一次6月末至7月上旬,第二次7月下旬到8月下旬;果穗有两种形状,稀疏型果穗较长、果粒近球形、排列比较疏松;紧密型果穗较短、果粒似桃形、排列比较紧促;桃形和近球形果粒不仅有大小之分,而且重量差异也极显著,前者的千粒重是后者1.5～2.2倍;五味子果穗长度与果穗重量存在显著的正相关性。

Analysis of relativity between fruiting and output of Schisandra chinensis in Heilongjiang Province

The region of Xing' anling mountain is the dominant growing district of Schisandra chinensis.To reveal the growth characteristic of the fruit and estimate the output of the fruit,we observed and recorded phenology of fruiting and the growth characteristics of the fruit fringe,and analyzed the relativity between the length and the weight of the fruits.The result shows that the fruit of Schisandra chinensis has two growth peaking period,one is from the last ten days of June to the first ten days of July;the o...
