| 摘 要： | 本文对24个马铃著品种(系)在旱作栽培条件下进行了评价,产量表现最高的为晋薯1号、乌盟851、坝薯10号和紫花白。块茎产量与茎叶覆盖度、根系拉力、茎叶干鲜重、根干鲜重、根数之间呈直线正相关,与出苗天数、块茎形成天数则呈直线负相关。根系拉力与根数、株高、茎叶干鲜重、根干鲜重呈直线正相关;与出苗天数和形成块茎天数呈负相关。结果表明,高根系拉力产生高块茎产量。因此,根系拉力可作为鉴定植株生长早期耐旱性的一个参数。

EVALUATION OF POTATO VARIETIES FOR DROUGHT TOLERANCE IN NORTH SHANXI |
| |
| Abstract: | A total of 24 potato clones were evaluated for drought tolerance under dry conditions.Jinshu No.1,Wumeng 851 and Bashu No.10 had the highest yield.Tuber yield had a positivelinear correlation to canopy,root pulling resistance(RPR),foliage fresh weight,foliage dryweight,root fresh weight and root dry weight,while tuber yield had a negative linear correla-tion to the days to emergence and the days to tuberization.RPR had a positive linear correla-tion to root number,plant height,foliage dry and fresh weight,and root dry and fresh weight.The results indicated that higher tuber yield could be obtained when the RPR is high.There-fore,the RPR could be used as a parameter to identify drought tolerance of plants during ear-ly stage of plant growth. |
