不同糯性高粱光合物质积累特点及源库关系分析

试验选取当前生产上较有代表性的非糯、半糯和糯高粱杂交种为试材,对光合物质积累、干物质积累、运输和分配等方面的特征特点进行了比较与分析。结果表明,灌浆期净光合速率（Photo）表现为非糯〉半糯〉糯;糯和半糯高粱干物质积累潜力较大,较非糯高粱还有一定的发展空间;干物质平均积累速率表现为非糯〉半糯〉糯,非糯高粱比半糯和糯的平均值分别高出3.85%和6.93%;茎鞘物质转化率非糯比半糯和糯分别高出56.33%和169.06%;非糯、半糯和糯高粱灌浆速率均呈＂慢-快-慢＂的＂S＂曲线变化,符合罗蒂斯蒂方程;非糯高粱灌浆速率较快,灌浆时期更为集中;干物质在茎秆中的比率半糯〉非糯〉糯;在籽粒中的比率糯〉半糯...

Summary:试验选取当前生产上较有代表性的非糯、半糯和糯高粱杂交种为试材,对光合物质积累、干物质积累、运输和分配等方面的特征特点进行了比较与分析。结果表明,灌浆期净光合速率（Photo）表现为非糯〉半糯〉糯;糯和半糯高粱干物质积累潜力较大,较非糯高粱还有一定的发展空间;干物质平均积累速率表现为非糯〉半糯〉糯,非糯高粱比半糯和糯的平均值分别高出3.85%和6.93%;茎鞘物质转化率非糯比半糯和糯分别高出56.33%和169.06%;非糯、半糯和糯高粱灌浆速率均呈＂慢-快-慢＂的＂S＂曲线变化,符合罗蒂斯蒂方程;非糯高粱灌浆速率较快,灌浆时期更为集中;干物质在茎秆中的比率半糯〉非糯〉糯;在籽粒中的比率糯〉半糯〉非糯,糯高粱收获指数较高,较半糯和非糯高粱可将更多的有机物转移至籽粒。

In this trial,taken more representative of the current production of non-waxy,semi-waxy and waxy sorghum hybrids as tested materials,their photosynthetic material accumulation,dry matter accumulation,transportation and distribution aspects characteristic features were studied. The results showed that： at the filling period the net photosynthetic rate（ Photo） performed the order of non-glutinous 〉semi waxy 〉waxy; The dry matter accumulation of waxy and semi-waxy sorghum had greater potential than that of non-glutinous sorghum,which still had a large inter-space for development; Dry matter accumulation rate expressed as average non-glutinous 〉semi waxy 〉waxy,and non-waxy sorghum was higher 3. 85 % and 6. 93 % than semi waxy and waxy,respectively. The stem and sheath conversion rates of non-waxy was higher 56. 33 % and 169. 06 % than that of waxy and semi-waxy; The non-waxy,semi-waxy and waxy sorghum grain filling rate showed slow-fast-slow‘S＇c
