海拔对'贵妃'芒果果实品质及农艺性状的影响OA

The altitude has a huge impact on mango cultivation in Yunnan province.In order to study the effect of altitude on the quality and agronomic traits of mangoes,this article taked'Guifei'mango from Yuanjiang county as the research object,and measured the agronomic traits and fruit quality of'Guifei'mango at three altitudes of 979.1,802.20 m,and 386.0 m.The results showed that altitude had no significant effect on agronomic traits such as tree height and trunk height.In terms of leaf length,leaf width,and petiole length,the altitude of 386.0 m was superior to those at 802.2 m and 979.1 m,and the difference was significant.The fruit traits such as single fruit weight and longitudinal diameter at different altitudes were best at an altitude of 802.2 m.As the altitude increased,the total sugar and total acid decreased.The influence of altitude on protein was relatively small.The comprehensive fruit quality indicated that the altitude of 802.2 m was better than that of 386.0 m and 979.1 m.Studying the impact of altitude on the growth and development of mangoes was of great significance for selecting the most suitable planting areas for mangoes.
