Abstract:

The distribution of 14C-assimilates in plant organs and different positions of ear in maize (Zea mays L.) was studied by feeding the ear leaf with 14CO2 at early period of kernel development. The results showed that ear was the main sink organ during kernel filling period, but the distribution of 14C-assimilates was uneven in different parts of ear. The distribution of 14C-assimilates in cob ranked as basal>middle>upper part, while the amount of 14C-assimilates in kernel sequenced as middle>basal>upper part of the ear. The sugar concentration in upper cob was not less (P>0.05) than that in middle part, but the content of reducing sugar in aborted kernels was significantly higher (P<0.05) than that in kernels at middle part of ear. It suggests the main reason of kernel abortion at ear tip in maizewould be low sink strength in kernels instead of assimilate deficiency.

Key words: Maize (Zea mays L.), 14C-assimilates, Distribution, Kernel abortion
