| 摘 要： | 为了了解球果生长发育和成熟时一系列生理生化特性和变化规律,对粗枝云杉球果内9种营养元素的季节动态变化进行了研究,研究表明:随着季节的变化,粗枝云杉球果内营养元素含量的大小顺序大致相同,即K>N>P>Mg>Ca>Fe>Zn>Mn>Cu,而变异系数大小顺序为:N(C.V%=50.65)>Ca(C.V%=25.24)>Fe(C.V%=23.08)>P(C.V%=21.19)>Cu(C.V%=14.75)>Mg(C.V%=12.36)>Mn(C.V%=11.04)>K(C.V%=9.50)>Zn(C.V%=7.79)。粗枝云杉球果中营养元素间的相关性为:N和P,Mg和Zn均呈显著正相关,P和K、Mg、Cu还有Zn均呈显著正相关,K和Mg、Cu还有Zn呈显著正相关。

| Abstract: | The seasonal dynamic changes of nine nutrient elements in the cones of Picea asperta were investigated in order to understand the physio-biochemical characteristics of cones in the time of growth and development and maturity.The contents of nutrient elements in cones of Picea asperta were roughly similar with seasonal changes as follows:K>N>P>Mg>Ca>Fe>Zn>Mn>Cu,but the order of coefficient of variation was:N(C.V%=50.65)>Ca(C.V%=25.24)>Fe(C.V%= 23.08)>P(C.V%=21.19)>Cu(C.V%=14.75)>Mg(C.V%=12.36)>Mn(C.V%=11.04) >K(C.V%=9.50)>Zn(C.V%=7.79).Correlation coefficient of nutrient elements in cones of Picea asperta were:there was a remarkable positive correlation between N and P,Mg and Zn;while P had a significant positive correlation with K,Mg,Cu and Zn;and did K with Mg,Cu and Zn. |
