Which is more resistant to high temperature, red axis corn or white axis corn?

This question is the same as "people with single eyelids grow taller or people with double eyelids grow taller". There is no inevitable connection between the two. But whether it is the red axis or the white axis, the one that can withstand high temperature is the good axis.

Let's take a look at the planting area of corn in Huang-Huai-Hai area. at present, the main varieties of summer corn in Huang-Huai-Hai are Zhengdan 958, Jundan 20, Ludan 981, Nongda 108, Jidan 7, Zhongke 4, Denghai 9 and so on. These kinds of corn have red axis and white axis, if the probability is large, the planting area is large, it must make people feel that the disaster is more serious under high temperature.

Different varieties of maize have different resistance to high temperature. let's take a look at the classification of high temperature resistance of a group of varieties.

The maize varieties with high temperature tolerance are: Dedan 121,Zhongzi 8, Yu'an 3, Zhengdan 1002, Zhengdan958, Weike 702, Liangshuo 88, Longyu 369, Dingxin 918, Xindan 29, Shengrui 999 and so on.

The maize varieties with moderate high temperature tolerance are: Aoyu 116, Denghai 605, Xiuqing 823, Shaodan 8, Lile 66, Jinsai 38, Zhongdan 909 and so on.

The varieties that are not tolerant to high temperature or have low tolerance are: Qiaoyu 20, Xindan 26, Yudan 6060, Liyu 86, Puyu 5, Yi 7008, Xianyu 808, Yuanyuan 9 and so on.

The maize varieties sensitive to high temperature are Xianyu 335, Huaiyu 5288, Zhengyu 10, Yudi 216, Xindan 38 and so on.

Maize varieties have great resistance to high temperature, but there are many effects on high temperature tolerance in the later cultivation process.

First, for example, postponing the sowing period of corn to avoid the hot weather during pollination. Second, the application of phosphate fertilizer and irrigation also improved the high temperature tolerance of maize. Third, the density of maize was reduced appropriately, and the individual resistance of the plant was enhanced. After excluding these factors, what kind of corn variety did you choose?

We mentioned above that maize varieties have different resistance to high temperature. let's take a look at the red axis corn and the white axis corn.

White axis are: Zhengdan 958, Zhongke 10, Liyu 35, Weike 702, Jixiang No. 1, Jundan 20 and so on.

Red axis are: Xianyu 335, Huanong 101, Denghai 605 and so on.

Combined with the high temperature resistance of different varieties and the color of red and white axis, the red axis is also resistant to high temperature, the white axis is also resistant to high temperature, and those that are not resistant to high temperature are also red axis and white axis. Therefore, it is obviously unfair to regard the red and white axis as an indicator of high temperature resistance.

There are also red axis varieties and white axis varieties planted in Huang-Huai-Hai area, but in terms of planting area, Zhengdan 958 and Xianyu 335 are the most prominent. Apart from other indicators of the growing period, the weather temperature this year is too high, which is obviously not conducive to the yield of Xianyu 335 corn. In the process of planting, many red axis varieties are also related to Xianyu 335. Therefore, under the high temperature stress this year, the difference in the yield of red and white axis came out.

Again, the red axis and white axis is not the index that determines the high temperature resistance of corn. Farmers should not be misled by the red axis and white axis. Choosing suitable and high temperature resistant corn varieties (regardless of the red axis and white axis) with appropriate management measures can obtain a more ideal yield.
