The Difference of High Yield and Nuts Quality of Juglans sigilltata cv. Lushui 1 at Different Elevations
摘要
Abstract
Setting the Juglans sigilltata cv. Lushui 1 in Lushui County as research object. Twenty-four sample trees which grew in 4 areas with different elevations were measured and analyzed the production capacity and nuts quality. Results shows that there were significant differences between the high yield and nuts quality of'Lushui 1'in different altitudes. The high yield at altitude range Ⅳ ( 2000~2200 m) was the highest, shoots increment was 196. 67%, shoots surviving ratio was 95. 67%, fruiting shoots rate was 79. 83%. The oil content rate, which was 69. 19%, at altitude range Ⅰ ( 1400~1600 m) was the highest, while coefficient of variation was 2. 67%. The protein content, which was 14. 71%, at altitude range Ⅲ (1800~2000 m) was the highest, while coefficient of variation was 9. 72%. Altitude was positively correlated with the mean value of 3 diameters, nuts weight, kernel weight, kernel rate, proportion of protein content, while is negatively correlated with nuts shell thickness, oil con-tent rate, fruit shape coefficient. In other words, with the increase of altitude, the mean value of 3 diameters, nut weight, kernel weight, kernel rate and protein content were increasing, while shell thickness, fruit shape coefficient and oil content rate were decreasing. Therefore, high yield, nut quality and product consistency were higher at altitude range Ⅲ and Ⅳ ( 1800~2000 m) .关键词
