玫瑰果实生长动态研究

以玫瑰8个栽培品种和3个野生类型为试材，对其果实生长过程的变化进行了研究。结果表明：栽培品种和野生类型横径生长规律不相同，“唐红”、“刺果”、“紫雁”、“一品紫衣”和“紫枝”5个栽培品种在生长过程中有一个相对快速增长阶段，其余3个栽培品种则呈现均匀稳定的增长趋势；3个野生类型均有两个相对快速增长阶段，分别出现在5月下旬至6月初和6月中旬至7月初。玫瑰果实纵径增长趋势大体一致，除“唐白”在5月下旬至6月上旬有一个相对快速增长阶段外，其余栽培品种和野生类型均呈现出均匀稳定的增长趋势，5月下旬至6月中旬是果实纵径增长比较明显的阶段。到7月中下旬，果实纵横径逐渐停止生长，达到最大值。

Study on Growth Dynamics of Rosa rugosa Fruit

Eight cultivars and three wild types of roses were taken as research materials to explore the variation of rose fruit during the growth period.The results were as follows.The growth rule of fruit diameter was not the same among the cultivars and wild types.There was a relative fast-growing stage in R.rugosa cultivar "Tanghong","Ciguo","Ziyan","Yipinziyi"and "Zizhi",while the fruit diameter of the other cultivars increased steadily.Three wild types of roses had two relative fast-growing stages in late May to...
