| 中文摘要: |
| 在旱地田间条件下,通过测定不同品系马铃薯伤流液的多少以反映根系吸收活力的大小,同时测定相应的生物产量和块茎产量。研究表明:在6个供试材料中,1-38品系的根系吸收活力最大,生物产量和块茎产量最高;马铃薯根系吸收活力越大,其相应的生物产量和块茎产量就越高。 |
| 英文摘要: |
| On the condition of dryland, bleeding sap of different potato strains was determined to reflect the absorption vitality of root system, and the biological yield and tuber yield were also measured. The results show that, among the six experimental strains, 1-38 produced the highest biological yield and tuber yield, and its absorption vitality of root system was the strongest. There is a very significant positive correlation between root absorption vitality and the yield, that is, the stronger is the absorption vitality of root system,the higher is the yield of potato on dryland. |
