Causes of Multiple Spike Formation in Maize
1, genetic factors Different varieties of corn have different degrees of occurrence. It is mainly due to the different development process of different varieties of axillary buds. Some varieties in the appropriate conditions under the conditions of multiple axillary buds are easily differentiated and developed multiple spikes. Some varieties have obvious advantages in the differentiation and development of the first axillary buds, thereby inhibiting the developmental process of the next section of the ear and not forming multiple spikes. 2. Apical male inflorescence growth is inhibited Promotes the development of the ear in many plants. One of the fastest and most significant metabolic effects caused by water deficit is the accumulation of hormone abscisic acid. This reaction also appears in corn plants. The tassel of corn is developed from the top male inflorescence and has a stronger growth potential. The female ear is developed from axillary buds, which is relatively slower than the tassel, and its growth potential is weaker. In the normal state of corn development, a single mature female inflorescence is produced on section 6 or 7. Also called the ear, this process is not suitable for external conditions. A short-term water deficit occurs when the top male inflorescence forms. Causes 57 to develop 2 to 3 mature female inflorescences. Causes multiple ears to occur. 3, carbon and nitrogen metabolism are not coordinated After jointing, corn enters the period of vegetative growth and vigorous reproductive growth. The growth of stems and leaves is large, and the male and female spikes are differentiated and the dry matter accumulation increases rapidly. At this time, if the soil is fertile and there is too much water and fertilizer, the metabolism of carbon and nitrogen will be uncoordinated, affecting the transport and accumulation of sugar and other minerals to the ear. Too much nutrients will promote the development and maturation of multiple female inflorescences. 4, unreasonable planting methods Different varieties. The density of plants is different and the density is too high. The leaves are shaded from each other, and the pollen does not easily fall onto the ears and cannot be fertilized properly. Coupled with the appropriate environmental conditions, promote the next ear development and maturation, thus forming multiple ears. 5, environmental conditions are not suitable During the drawing of a male flowering period. Corn growth and development under normal conditions. If you encounter sunny weather. Tassel does not loose powder or even loose powder, but because of the rain of the female ear filaments, the pollen grains swell and rupture. The impact of fertilization directly leads to empty ears and no seeds, so that excess nutrients are redistributed to the next section. This leads to multiple spikes.
