Maize growth period and the relationship between light

Maize is a short-day crop, but the requirements for short-day sunshine are unreliable, such as accelerated development in 8 to 12 hours of light, but it can also bloom and bloom under longer light for 18 hours or in continuous light. Just a slight delay in the growth period, therefore, is not a typical short-day crop. Generally early-maturing varieties are insensitive to light, and late-maturing varieties are more sensitive to light.

To capture the high yield of corn, the more important is the light intensity. During the growing period, dark and rainy, when the light intensity is insufficient, it will cause corn to greatly reduce production. After the onset of strong organs, under low light, pollen development is incomplete, which seriously affects fertilization. The filaments of the female ear were extracted for about 10 days. When the weak weather was dark and rainy, the flowering was delayed, the ear was not full, and the lack of grains was more. Mature corn must also have sufficient light to facilitate dry storage of the ear.
