| Abstract:The main biological characteristics of 'Heijin'and 'Jinfu' were observed by field observation and laboratory testing. This study may provide references for adaptive exploration and management of 'Heijin' and 'Jinfu' in the northslope of Qinling Mountains.Taking Actinidia chinensis cv.Jinmi,Actinidia deliciosa cv.'Hayward','Xuxiang' and'Yate,'Actinidia arguta var. purpurea as controls,the results showed that the germination period, flowering period,fruit-ripening period of 'Heijin' were in mid-March,early May and mid-September, respectively,it was an early-maturing line in north slope of Qinling Mountains.The germination period, flowering period,fruit-ripening period of 'Jinfu' were late March,early May and late October, respectively，and it was a late-maturing line.Both of 'Heijin' and 'Jinfu' had unisexual and typical dichasium.The fruiting branches of 'Heijin' were short fruit branch，accounting for 58.49%,and fruit-setting rate was higer (88.05%).Long fruit branch and highest fruit-setting rate of 'Jinfu' accounted for 66.89% and 99.75%，respectively.Fruit of 'Heijin' was cylindrical,fruit shape index was 1.25,the average fruit quality was 93.12 g,color of flesh was gold yellow;the average soluble solids content,titratable acid and dry matter content were 16.76%, 0.17% and 19.95%, respectively.For 'Jinfu', its fruit was subcylindrical,fruit shape index and the average fruit quality were 1.77 and 96.96 g,respectively; the average soluble solids content,titratable acid and dry matter content were 15.61%,0.11% and 18.99%,respectively.The biological characteristics of 'Heijin' and 'Jinfu' are genetically stable and have high development prospect. |
