| 摘 要： | 1989年3月至1990年3月间,在亚热带地区对UC157幼龄芦笋植株地下部的干物质积累和碳水化合物含量变化规律进行了研究.结果表明:芦笋地下部一年内有两次生长高峰,地下部干重,肉质根长之度和数目的变化与生长天数呈三角函数关系,函数的周期为114(d);在母茎形成期,肉质根碳水化合物含量有下降趋势,母茎形成后,内质根碳水化合物含量迅速增加,直到母茎衰老。

| Abstract: | The pattern of dry matter(DM)accumulation in roots and rhizomes, the concentrations of storage carbohydrate in roots,using Asparagus Cultivar UC157 were studied in the experiment through a year from March, 1989 to March, 1990. The growth and DW increasing curves of the underground portion appeared on trigonometric function from March to Nov. The function cicle is 114 days. It ceased for dormancy in the winter. There was a decline of DW and carbohydrate in roots as new shoots developed. After the first ferns had expanded, root carbohydrate concentration and DW again increased. |
