| Source-sink relationhips is a controversial topic. Some workers assert that grain yield in corn is limited by availability of assimilate during the grain filling period. Others have reported the sink size as the limiting factor. In this research, I studied the effects of assimilate availabilibty on kernel growth rate and final weight by investigating the effects of altered source/sink ratios on soluble sugars, starch and nitrogen content in plant parts of maize. Special attention was given to plant's compensatory response such as soluble carbohydrates and nitrogen redistribution to the grain. Two genotypes: M14 x W64A and Pionner-brand '3780', were grown in field plots at St. Paul, Mn in 1982. The treatment were arranged in a split plot manner in a... |
