黄菠萝结实规律的研究

Study on The fruiting regularities of Phellodendron amurense Rupr

黄菠萝(Phellodendron amurense Rupr.)属于芸香科(Rutaceae)、黄柏属(Phelloden-dron),是我国东北地区著名的三大珍贵阔叶树种之一,第三纪孑遗物种,特别是以生产地道中药材关黄柏而备受重视。我们通过对黄菠萝的结实规律研究,认为黄菠萝结实有明显的周期性,每隔3-4年出现一次丰产年;人工林种子产量比天然林产量高出近两倍,浆果大,种子大而饱满;人工林与天然林的种子发芽率均超过85%,人工林种子发芽率高出天然林发芽率的1.4%。

Phellodendron amurense Rupr.is one of three high-value broad-leaved tree spcies.It is relic plant of the tertiary period.It is famous especially for it's medicinal value.According to our research,the fruiting periodicity of Phellodendron amurense Rupr.gets is obvious,and its fruiting periodicity is 3 to 4 years.The seed output of Plantation is 2 times more than natural forest,and the seed is bigger and fuller.The germination percentage of both natural forest and plantation is more than 85%,but the percentage of plantation is still 1.4% higher than natural forest.
