KERNEL GROWTH AND DEVELOPMENT AT TWO POSITIONS ON THE EAR OF MAIZE (ZEA MAYS)

摘要: Studies were conducted in 1975 at Guelph, Ontario, to examine kernel growth and development two positions on the ear of maize (Zea mays L.) hybrids United-H106 Funk’s G-4444. Development kernels base tip was studied from 2 wk before silk emergence black layer formation. Kernels lagged 4–5 days behind during period start onset LDMP (the linear dry matter accumulation kernels). Tip 25% ears ceased LDMP. Differences weight formation between basal G-4444 ears, which tip-kernel had not could be attributed a shorter duration lower rate did stop an ear...
