摘要(Abstract):

根据姜黄器官生长的变化特点,可将姜黄个体发育过程划分为3个时期。姜黄一生形成130叶,以苗期形成叶最多,共形成80叶。叶面积在苗期较小,至9月下旬达最大值33029cm2/株,叶面积指数(LAI)495。净同化率(NAR)在根状茎充实期最高354g/m2·d。在苗期,干物质主要分配到叶部;在根状茎充实期,干物质主要分配到子姜。姜黄一生中发生2次生长中心的转移;当子姜生长率(CGRr)与叶生长率(CGRt)曲线相交时,可作为生长中心由叶向子姜转移的依据。
Based on the research of growth of organs,accumulation of dry matter,distribution of photosynthetic production and displacement of growth centre,the growth of turmeric can be divided into three stages.There are 13 leaves in the life of turmeric.Leaf formation takes place rapidly to form 8 leaves in the seedling stage.The leaf area and increase of dry matter per day in roots and leaves are smaller or lower in the seedling stage.In the daughter rhizome formation stage,NAR reaches the maximum (3.54/m 2·d),and the leaf area reaches the maximum(3302.9cm 2/plant, LAI 4.95).Before the daughter rhizome formation stage,more than 75% of dry matters are distributed in leaves,and in the daughter rhizome formation stage,50%~75% of dry matters are distrbuted in leaves.In the late growing period,more than 40% of dry matters are distributed in the daughter rhizome.The growth centre of turmeric changes two times in life.When CGRr is equal to CGRt,the crossing of CGRt and CGRr curves may be regarded as the evidence of the transfer of growth centre from leaves to daughter rhizome.
