| 摘 要： | 芽生长过长和细弱的种薯,需要抹芽播种,块茎表现出生理年龄老化,干瘪皱缩。抹芽种薯出苗晚,苗期的抗逆性差,植株生长势较弱,早衰。植株主茎细,匍匐茎多,形成块茎小而多,单株产量低、单薯重量低,商品率不高。最终产量降低15.56%~49.97%。单薯重量减少0.008~0.044 kg,单株重量减少0.01~0.22 kg,商品薯率减少12.49%~45.08%。 |

| Abstract: | The potato seed tubers with long and thin buds and the senile tubers would show older physiological age,hairsprouts and shrivel.Farmers had to break off the buds of seed potato before sowing.The yields of plants with low growth vigour,thin main stem,more stolons and more small tubers,and lack of the resistance to unfavourable environment.were deceased by 15.56 %-49.97 %,the weight of each plant was deceased by 0.01-0.22 kg,The weight of one tuber was deceased by 0.008-0.044 kg,and the ware potato was deceased by 12.49 %-45.08 %.Therefore it was very important to choose seed potato in likely physiological stage to avoid long and thin buds in potato production. |
