摘要
田间试验结果表明,蓖麻主穗长度不同,主穗的蒴果数、籽粒重均有差异,样株主穗长度在61～70 cm之间时,其蒴果数和籽粒重均较大,其次为主穗长度在71～80 cm 的样株,再次为主穗长度在51～60 cm 和41～50 cm 的样株,但百粒重之间差异不显著;不同主穗长度下,各分枝的籽粒重和穗粒数也不同,41～50 cm 的植株最大,61～70 cm 的反而最小。从生物量的分配来看,营养体的比重较大,生殖体(主要是籽粒)所占比重较小。经统计回归建立了籽粒重与根重、籽粒重与茎叶重、茎叶重与根重、总生物量与根重的数学拟和模型,为进一步探讨其间的关系提供了参考依据。
The field test results showed that the different length of main ear is different in grain weight and number of capsule in castor.The number of capsule and grain weight were high when the length of main ear is 61～70 cm,and middle when 71～80 cm,and low when 51～60 cm and 41～50, But HKW is not significant.When under different length of main ear the grain weight and grain number of branch is also different,which 41～50 cm is biggest and 61～70 cm is smallest.The proportion of vegetation is higher than of seed in distribution of biomass.Some mathematics models were established between grain weight and weight of root,grain weight and weight of stem and leaf, weight of stem and leaf and weight of root,biomass and weight of root.Those models were good for further to study their relationship.
