Effects of Low Position-directional Fruiting Guided by Physical Methods on Fruit Traits of Banana
摘要
Abstract
Banana plant has the characters of fruiting in high position and of hanging in non-fixed orientation,which is not conducive to the flower removal,bud removal breaking,pesticide spraying,bagging and harvesting of banana fruit in production,and make it vulnerable to wind damage,causing lodging and breaking.In order to reduce the height posi-tion of banana fruit,make it hang fruit directionally,facilitate management,realize mechanized harvest and improve field management efficiency,a guide outlet was excavated at the lower position on one side of banana pseudostem by physical method to guide banana to fruit at the lower position and predetermined direction,and the differences in fruit characters between physically induced fruit and naturally formed fruit were studied.The results showed that opening the outlet by physical method could guide the banana fruit grow in a low position and a predetermined direction.The aver-age fruit yield per plant was 21.47 kg(with a variation range of 11.5 kg to 36.15 kg),the average number of fruit fingers per plant was 187(with a variation range of 137 to 237),the average weight of single fruit finger was 120 g(with a variation range of 60 g to 190 g),the average length of fruit axis was 41.82 cm(with a variation range of 27.5 cm to 54.5 cm),the average length of outer arc of fruit finger was 17.88 cm(with a variation range of 13.4 cm to 21.1 cm),the average perimeter of fruit finger was 11.44 cm(with a variation range of 9.6 cm to 12.9 cm).Correlation and regression analysis showed that the fruit weight per plant,fruit axis length and fruit finger length were significantly negatively correlated with the time interval from opening outlet day to heading fruit day,respectively.Compared with the natural heading fruit,there was no significant difference in average fruit weight per plant,average total number of fruit fingers per plant and average number of fruit fingers per comb,there was no significant difference in the thickness of the fruit fingers and the curvature of the fruit fingers;but there was significant difference in average weight of single fruit and of fruit axis respectively;The length of fruit axis and the length of fruit finger and the spacing between fruit combs was significantly shortened respectively,the differences are all very significant.关键词
