杂种玉米在生长季节的大部份时间内,在茎秆中积累了大量的糖份。到玉米生长季节终了时,茎秆中积累的糖份逐步向籽粒中转移。玉米茎秆在成熟期的含糖量对植株倒伏有重大关系。据加拿大农业部研究人员称,杂种玉米易于倒伏主要是由于茎秆内糖份的枯竭。有些杂种玉米之所以能抗倒伏一般是因为茎秆内保存了一定的糖份。在糖份转移后茎秆即易腐烂并倒伏。环境因素也能影响玉米秆在成熟时糖的储存量。任何外界压力,如早霜、干
Hybrid maize accumulates a large amount of sugar in the stalk for much of the growing season. By the end of the corn growing season, the accumulated sugar in the stalk gradually migrates into the grain. Corn stover in the maturity of the sugar content of plant lodging a significant relationship. According to researchers from Canada’s Ministry of Agriculture, the easy lodging of hybrid corn is mainly due to the depletion of sugar in the stem. Some hybrid maize is generally resistant to lodging because the stalks retain some sugar. Stalks are perishable and lodging after sugar is transferred. Environmental factors can also affect corn stover sugar storage at maturity. Any external pressure, such as early frost, dry
