【摘要】 以巴西蕉为试材,在人工气候箱香蕉组培苗生根培养试验,结果表明:在不同温度和不同光照条件下,香蕉组培苗生根表现出一定的规律,叶数、根数、根长3项指标与培养天数之间存在显著的线性关系。对各温度不同光照的生根指标与天数关系的散点图进行线性回归,建立两者关系的相应数学模型,统计分析结果显示,在25、28、31℃条件下香蕉组培苗的叶、根发生所需时间没有明显差异,不同光照之间也几乎没有差异;应用本试验建立的3个数学模型对不同培养条件下的香蕉生根组培苗进行检验,实测值与预测值的相对误差在10%以内。更多还原

【Abstract】 Brazil banana was taken as experimental material.The experiment was carried out in the artificial weather box.The mathematical models describing the relationships between formation of roots,the growth of leaves of tissue culture plantlets of banana and culture days under different conditions were built.The results of regress analysis showed that using the same rooting material,and controlling the different temperatures and light intensity in the artificial weather box,there is certain regulation in the rooting of plantlets of bananas,by the statistics analysis,there are linear relationship between culture dates and leaves,culture dates and roots,culture dates and the length of roots,and their mathematics model were established.The time of the root formation and the leaf growth has no significant difference among25,28 and 31 ℃,and among different lights,either.The results have shown that the relative errors between the values measured and the ones estimated by the equation are within 10%.更多还原
