摘要: <正>运用电感耦合等离子发射光谱仪(ICP),分析了马尾松具有代表性的10个种源在休眠期间针叶内15种矿质灰分营养元素含量变异状况。结果发现:(1)马尾松针叶内15种灰分营养元素含量的排序:钙>钾>镁>铝>钠>硅>锰>铁>锌>铜>镍>钴>钼=硒(钼和硒低于ICP测定范围)。(2)马尾松针叶内钙、铝、钠和硅含量相对较高是该树种抗逆性强的见证,也是该树种长期分布于南方酸性土壤的结果。(3)多数矿质灰分营养元素在不同种源马尾松针叶内含量呈显著差异,并表现出南部种源高于北部种源,西部种源高于东部种源的倾向。但锰的含量却是北部高于南部种源。(4)从理论上进一步证实广西宁明和忻城种源为优良种源。而安徽霍山、浙江庆元为较差种源。

Abstract: The variation of the fifteen mineral elements in the needles of the ten provenance of Masson pine(Pi-nus massoniana Lamb. ) were studied during the period of dormancy with 1CP for the first time. The results were as follows, (1)The order of total content of the fifteen mineral elements as, Ca>K>Mg>P>Al>Na>Si> Mn>Fe>Zn>Cu>Ni>Co>Mo=Se. The content of Ca was 4017. 86 ug·g-1 in dry needles. But, the content of Mo and Se was lower than the range of 1CP. (2)Masson pine growing in the southern acid soil made it absorb more Ca, Al, Si and Na to tolerant environmental hardiness. (3)The variation of Ca, K, Al, Na, Si, Mn, Fe, Zn, Ni and Co in the needles was very significant. From south to north and west to east, the content of the nutrition elements was lower down. But Mn appeared contrary. (4) According to the variation of the mineral nutrition, Masson pine of Ningming and Xincheng in Guangxi province was the best provenance, Huashan in Anhui province and Qingyuan in Zhejiang province were the worst, combined with the growth data and mineral content.
