【摘要】 马铃薯块茎空心多发生在100g 以上的大块茎中,但品种之间块茎大小与块茎空心率高低没有绝对的正相关关系。决茎形成期至块茎迅速增大期间的茎叶生长量小,茎叶重量与块茎重量的比值高,块茎空心率高;块茎形成期至块茎迅速增大期之前块茎生长慢,进入迅速增大期后,块茎增大速度快,块茎大, 块茎空心率也高。更多还原

【Abstract】 Tuber hollow heart takes place in most of the tubers which weigh over 100 g, but for different varieties there is no absolute positive correlation between the percentage of tuber hollow heart and tuber size.During the period from the tuber formation to tuber expansion,the growth of leaves and stem is slow,and the weight ratio of upground part to the tubers is high,and the ratio of tuber hollow heart is high,too.Since the tuber begin to form till the beginning of the period of tuber expansion,the growth of tubers is slow,but when the period of tuber rapid expansion comes,the tuber expands quickly,the size of tuber is large,and the ratio of tuber hollow heart is high.更多还原
