"Heiye" litchi variety improvement by top grafting
[Objective]Variety improvement of "Heiye" litchi by top grafting was conducted to provide the best scion combination for litchi quality improvement and growth period adjustment in Guangxi.[Method]Heavily retroactive pruned 13 years old "Heiye" Litchi tree,12 litchi varieties such as "Feizixiao","Guifeihong" and "Caomeili" were top grafting.Survival rate,growth and yield after top grafting were compared and analyzed.[Result]The results showed that the highest rate of graft living was "Feizixiao" (86.6％),then "Guihuaxiang" (74.6％) and "Guifeihong" (71.3％),and the lowest was "Yingshanhong" (17.1％)and "Jizhuili" (26.1％)."Guiwei","Wuheli","Qinzhouhongli" and "Heli" appear swelled in grafting position,grew weakly with yellow leaf blade and had no yield.Eight varieties,"Guifeihong","Caomeili","Guinuo","Yingshanhong","Jizuili","Feizixiao" and "Mili",grew and produced fruit normally.The average yield per plant grafting after 4 years was around 15.0 to 49.5 kg.The highest was "Feizixiao" (49.5 kg)and the yield of "Guifeihong" was 40.6 kg.[Conclusion]With "Guiluo","Yingshanhong","Guihuaxiang" and "Mili" as scion grafted onto the intermediate stock of "Heiye",the affinity is good,hence they are the optimal scion combination.
