本实验研究了大豆叶绿素含量与单株生物学产量的关系、几种谷类作物的叶绿素含量及其测定条件。1.在8～30℃范围内温度对叶绿素提取液的影响甚微,为了防止光氧化破坏,必须在黑暗中保存。2.大豆叶片叶绿素含量在4～5毫克/分米~2范围与单株生物学产量成正相关。3.从生育期看,糜子、谷子、高粱、玉米叶片的叶绿素含量都以幼穗分化为最高,小麦是开花末期为最高,水稻是以灌浆期为最高。在后期从叶位看,糜子是顶叶,谷子是第2叶,高粱是第4叶,小麦是顶叶,水稻是第2叶,玉米先是果穗叶及其上、下1叶,以后是果穗以上1、2叶的叶绿素含量为最高。
This experiment studied the relationship between the chlorophyll content of soybean and the biological yield per plant, the chlorophyll content of several cereal crops and the determination conditions. 1 in the temperature range of 8 ~ 30 ℃ chlorophyll extract little effect, in order to prevent photooxidation damage, must be stored in the dark. The chlorophyll content of soybean leaves was positively correlated with the biological yield per plant in the range of 4 ~ 5 mg / dm ~ 2. From the growth period, the chlorophyll content in leaves of millet, millet, sorghum and maize all differentiated to the highest in spikelets, the highest in late flowering stage and the highest in grain filling stage. From the leaf position in the late view, the millets are the parietal, millet is the second leaf, sorghum is the fourth leaf, wheat is the top leaves, rice is the second leaf, corn first leaves and its upper and lower leaves, followed by the ear Above 1, 2 leaf chlorophyll content is the highest.
