为加快香石竹试管苗的繁殖速度 ,对培养基中营养物质的变化进行了研究 .结果表明 ,香石竹试管苗吸收磷、氮符合幂函数曲线 ,培养过程中培养基的糖含量直线下降 ,通过回归分析 ,培养基中 PO43- ,NH4+ ,NO3- ,总氮与糖的含量对其培养时间的回归系数分别为 - 0 .9490 ,- 0 .90 90 ,- 0 .932 0 ,- 0 .940 0 ,- 0 .90 6 0 ,经统计检测都达到极显著水平 .试管苗高生长与鲜重增长遵循双曲线函数关系 ,而丛生芽分化遵循负指数函数关系 ,其相关系数分别为 0 .8496 ,0 .993.0与 0 .882 4,经统计检测均达到极显著水平
In order to speed up the propagation of test-tube plantlets, the changes of nutrients in the medium were studied.The results showed that the absorption of phosphorus and nitrogen in the plantlets of Carnation was in accordance with the power function curve, and the sugar content in the medium decreased linearly Regression analysis showed that the regression coefficients of the contents of PO43-, NH4 +, NO3-, total nitrogen and sugar in culture medium were -0.99490, -0.9090, -0.0932, -0.0940 0, -0.9060, respectively, all reached the extremely significant level by statistical test.The hyperbolic function relationship was observed in the growth of test tube plantlets and fresh weight, while the differentiation of clustered buds followed the negative exponential function with the correlation coefficients of 0.8449 , 0 .993.0 and 0 .882 4, respectively, and reached the extremely significant level after statistical tests
