To explore the regulation of the growth of fruit of Amomum tsaoko and the factors influencing the weight of fruit.
To compare and analyze the quantitative multistate character of fruit and seed of Amomum tsaoko.
The quantitative multistate character of fruit and seed of Amomum tsaoko in populations and between populations were abundant. There was positive relativity between the rate of fertilization of ovule and the rate of fructify and this indicated the different heredity character among plants. The weight of fruit was mainly decided by the weight of seed regiment, The more the seed quantity, the larger the weight of seed regiment, and the larger the weight of fruit, then the higher the yield. The variety of the weight of fruit and the quantity of seed presented peak form along with the proper order of fruit growth in inflorescence but had no relativity.
The abundant quantitative multistate character of fruit and seed of Amomum tsaoko provide the abundant materials for selecting good varieties. For high yield we should not only choose plants with high rate of fructify and high rate of fertilization of ovule the, but also pay attention to the influence of pollination to yield.
探讨草果果实生长规律及影响果实重量的因素。
对草果果实与种子的数量多态性特征进行比较分析。
草果居群内及居群间果实与种子的数量多态性特征丰富。胚珠受精率与结实率呈正相关，表明植株间存在不同的遗传特性。果实重量主要由种子团重量决定，种子数量越多，种子团重量越大，果实重量越大，产量越高。果实重量和种子数量的变化随果实在花序中生长的适当顺序呈峰值形式，但无相关性。
草果果实与种子丰富的数量多态性特征为优良品种的选育提供了丰富材料。为获得高产，不仅要选择结实率高、胚珠受精率高的植株，还要注意授粉对产量的影响。
