Effects of different rootstocks on the growth and fruit quality of Cuiguan pear
摘要
Abstract
The fuzzy comprehensive evaluation method was used to study the effects of bean-pear and moldy-pear rootstocks on the growth and fruit quality of Cuiguan pear.The results showed that the height of Cuiguan pear tree with wild 3 and j2-29 rootstocks was higher,and the diameter of scion cross-section was larger.The Cuiguan pear grafted on the bean 5 rootstock had the highest germination rate and the greatest new shoot diameter.The phenological period of Cuiguan pear grafted on the wild 3 and j2-29 rootstocks was earlier.The number of flower buds of Cuiguan pear grafted on the wild 3 and j2-29 rootstocks was small,and their proportion of short branches was high,and the difference in fruit size and yield between them was not significant.The Cuiguan pear grafted on wild 3 rootstock had the highest soluble solid content(13.03％),and its sucrose content in juice was the highest(40.74 g/L),which was nearly twice that of other rootstocks.The content of glucose,fructose,and sorbitol in juice was also the highest for Cuiguan pear grafted on wild 3 rootstock,and its total acid content in juice was the highest(2.69 g/L)as well,and the sugar-acid ratio was large.Cuiguan pear grafted on j2-29 rootstock had a higher sugar content in juice and the lowest percentage(60.00％)of trunk ring rot.The fuzzy comprehensive evaluation of 12 indicators of growth and fruit quality of Cuiguan pear showed that the ranking order of evaluation value was wild 3 rootstock＞j2-29 rootstock＞bean 5 rootstock＞j1-27 rootstock.In summary,the wild 3 rootstock was superior to other rootstocks,and the quality of Cuiguan pear was good,which was the best grafting rootstock for Cuiguan,followed by j2-29 rootstock.关键词
