PGR-1对槟榔矿质营养水平及其变化的研究

An Investigation into the Effect of PGR-1 on the Variations in Mineral Contents and Nutritive Value of Arena eatechu L.

喷布PGR-1后,观测槟榔年周期各物候期间叶、花、果实矿质元素含量,营养水平及其变化规律,不同叶层叶面积加大20.8～37.47cm^2,叶干物质累积增加4.66～6.56g,进而加强花序营养水平,提高成花量和座果率。

The investigation was conducted to find out the effect of PGR-1 (spurting) on variations in the mineral contents and nutritive values of the leaf, flower and root of Areca catechu in different phenophases of the year. The result shows that PGR-1 helps to expand th leaf ares of different leaf segments by 20.8 to 37.47cm^2 and increase the dry matter by 4.66 to 6.56g, so as to promote the nutritive value of inflorescence and thus raise the flowering and fruitication rate.
