Influence of Three Different Factors on Grafting Propagation of Pouteria campechiana(Kunth)Baehni
To improve the survival rate of Pouteria campechiana(Kunth)Baehni grafted seedlings and explore the best grafting methods,Xiantao No.1 P.campechiana(Kunth)Baehni was used as the test material to explore the effects of scion type,grafting method and grafting period on the grafting survival rate of P.campechiana(Kunth)Baehni.The results showed that scion type,grafting method and grafting period had significant effects on the grafting survival rate of P.campechiana(Kunth)Baehni.The survival rate of graf-ted seedlings with lignified branch scion was the highest(99.33％),followed by that of with semi-lignified branch scion(80％),and terminal bud scion was the lowest(58.67％).The survival rate of split grafting was the highest(98％),followed by cut grafting(90％)and union grafting(61.33％).The survival rate of graft-ing in spring was the highest,up to 100％,and the growth of grafted seedlings were vigorous.The survival rate of grafting in autumn was 85.33％.The survival rate of grafting in winter was the lowest,only 55.33％,and the growth of grafted seedlings was the worst.Based on the above results,the survival rate of grafted seedlings of P.campechiana(Kunth)Baehni was the highest when the lignified branches were grafted by split grafting in spring(from March to April).This study provides the technical support for efficient breeding of P.campechiana(Kunth)Baehni.
