在花生生育期间,叶片中总糖含量和碳氮比值幼苗中期和饱果成熟末期较高,结荚期较低,可溶糖含量在花针期和饱果成熟中期较高,结荚中期较低。而全氮含量则相对稳定;叶片中糖氮比值的变化与花生各阶段生育进程及水平有关,因而可作为高产花生群体生育调控的依据之一;荚果干物质积累符合Logistic生长曲线,但在积累过程上存在差异。理论上认为群育101比花37稳产性更好;荚果中脂肪、可溶糖、淀粉和蛋白质相对含量除脂肪随荚果成熟度的增加上升外,其余3种物质均有不同程度的降低,但绝对含量均随荚果的发育而增加;荚果发育初期淀粉合成速度大于脂肪,而中期脂肪的合成占主导地位。果针入土后20~50d内是荚果生化活动旺盛时期,此期内创造适宜的生态环境,有利于花生优质高产。
During the growth period of peanut, the total sugar content and C / N ratio in leaves were higher in mid-stage and full-ripe stage, lower in pod-setting stage, higher soluble sugar content in mid-flowering stage and mid-maturity stage, low. While the content of total nitrogen was relatively stable. The change of the ratio of sugar and nitrogen in leaves was related to the growth process and the level of peanut at all stages, which could be used as the basis for birth control of peanut population. The pod dry matter accumulation accorded with Logistic growth curve, There are differences in the process. In theory, population 101 was more stable than flower 37. The relative contents of fat, soluble sugar, starch and protein in pod except the fat increased with the maturity of pod increased, but the other three substances all decreased to some extent, however, The absolute content increased with the development of pod; the rate of starch synthesis was higher than that of fat in the early stage of pod development, while the synthesis of mid-stage fat dominates. Within 20 ~ 50 days after harvesting the needles, the pod biochemical activity is exuberant, during this period, creating a suitable ecological environment is conducive to the high quality and high yield of peanuts.
