【摘要】 云南省南部,云南松和思茅松混生地区有较丰富的β-蒎烯资源。根据这一地区采集的大量腊叶标本和松脂样品的鉴定、分析结果认为:β-蒎烯含量在1％左右的是思茅松;β-蒎烯含量在50％以上的是云南松,由于该地区云南松的β-蒎烯含量显著高于其他地区的云南松(4—8％),所以将它定为云南松分布南部边缘地区的一个特殊地理类型—高β-蒎烯云南松。更多还原

【Abstract】 β-pinene resource is rich in the south of Yunnan Province, where mixed forest comprising Pinus yunnanensis and P.kesiya var.. langbianen-sis exists. According to the results of identification and analysis of large number of samples of pine trees and oleoresins collected from that area, P. kesiya var. langbianensis contains about 1% β-pinene, while P. yunnanensis contains more than 50%. As its β-pinene content is significantly higher than that of the same species grown in other areas (4-8 % β-pinene),P. yunnanensis growing in the particular area located on the southern border of the distributing area of that species is considered as a specific geographical type - high β-pinene yielding type.更多还原
