| Spraying the different concentration of 6-BA+K2SO4 on the "Chang Fu 2#"apple trees at the eight age ,reducing sugar,soluble sugar ,starch ,all kinds of mineral nutritions (K,Ca,Mg,Cu,Fe,Mn,Zn)and mean fruit weight were measured and analysed.The results were as follows: (1)The result showed that the treatments could improve the contents of mineral nutritions in the fruits. Treatment 5 was the best among all the treatments. The contents of mineral nutritions in the fruits except Ca with all treatments, ,were remarkably higher than those of the control.The contents of K,Ca,Mg,Fe,Mn in the fruits of the treatment 5 were the highest among all the treatments and the control. (2) The significant analysis for total sugar,soluble sugar,reducing sugar in the fruits in two years showed that the contents of total sugar,soluble sugar,reducing sugar in the fruits of the treatment 5 were the highest and those of the control is the lowest, those of all the treatments were remarkably higher than those of the control.The result of the treatment 5 was the best. (3)The result of mean fruit weight revealed: all the treatments could remarkably improve the fruit weight. The different reached to the level of the most significance. (4)The correlation analysis between mineral nutritions and total sugar revealed that during maturation period, there were the positive correlation between the contents of Mg,Fe,Zn in the fruits and the content of total sugar in the fruits. For the treatment 5, the positive correlation reached to the level of significance. There were the negative correlation between the contents of K,Ca,Cu,Mn and the content of total sugar in the fruits. (5) The correlation analysis between all mineral nutritions ,total sugar and mean fruit weight revealed that there were the positive correlation between total sugar and mean fruit weight. For all the treatments, the positive correlation reached to the most level of significance. The correlation of the treatment 5 was the closest among all the treatments, the correlation coefficient was 0.9694.The correlation of the control didn't reach to the level of significance. There were the negative correlation between the most of mineral nutritions in the fruits and mean fruit weight. The negative correlation between the content of Cu in the fruits and mean fruit weight reached to the most level of significance for all the treatments and the control. The negative correlation between the content of Ca in the fruits and mean fruit weight for the treatment 4 reached to the most level of significance. The negative correlation between the content of Fe in the fruits and mean fruit weight for the treatments 1-4 and the control reached to the most level of significance . |
