| 中文摘要: |
| 选用冀张薯8号、夏波蒂2个马铃薯品种，对不同生育
时期的干物质积累与分配进行比较。结果表明：马铃薯的全株干物质积累呈现S型曲线，马
铃薯生育期间不同器官干物质积累与分配中心依次为叶片和根、地上茎、块茎；冀张薯8号
和夏波蒂相比，叶片和地上茎的干物质积累峰值前者比后者来得晚，根和块茎的干物质积累
峰值在同一时期出现，在整个生育期叶片、地上茎、根、块茎干物质积累量前者均大于后者
，就产量而言，前者高于后者，且增幅为23.9%。 |
| 英文摘要: |
| Two potato cultivars, including Jizhangshu No.8 an
d Shepody, were tested to compare the accumulation and distribution of dry matte
r at different growth stages of potato. The results showed that the dry matter a
ccumulation of whole plant was in line with “S” curve. The central organs for
the accumulation and distribution of dry matter at different stages were success
ively leaves, roots, stems and tubers. The peak value of dry matter accumulation
in leaves and stems of Jizhangshu No.8 appeared later than that of Shepody, whi
le the peak value of dry matter accumulation in roots and tubers appeared at the
same stage for the two cultivars. In the whole growth period, the accumulation
amounts of dry matter in leaves, stems, roots and tubers of Jizhangshu No.8 were
totally larger than those of Shepody. As a result, the yield of Jizhangshu No.8
was 23.9% higher than that of Shepody. |
