玉米干物质积累变化规律,前人已做了不少研究,但大都着眼于群体或局限于某个生育时期或某些器官的研究。而对玉米体内可溶性糖和氨基酸的变化规律,体内养分变化之间的关系则报道很少。 本研究是以玉米丰产群体为条件,以个体为主要研究对象,在全生育期对各器官干 Many studies have been done on the variation of dry matter accumulation in maize, but most of them focus on the research of groups or limited to a certain period of growth or certain organs. However, the relationship between the changes of soluble sugar and amino acids in maize and the change of nutrient in body is rarely reported. This study is based on the conditions of corn high yield population, the individual as the main research object, during the whole growth period of each organ dry
