本文研究叶部乳管系与橡胶苗期产量预测的关系。观察到叶片主脉乳管与侧脉乳管相通;叶片主脉乳管数由叶基向叶尖逐渐减少;侧脉乳管数由近主脉一端向叶缘逐渐减少;叶片中部的侧脉乳管数较多,然后向叶基和叶尖逐渐减少。相对来说,侧脉乳管和小叶柄乳管个数与其成龄芽接树的产量之间分别呈显著和极显著相关。小叶柄皮层乳管数与其成龄芽接树头5年产量之间呈显著相关(r=0.4048)。韧皮部乳管数与其成龄芽接树头5年产量之间呈极显著相关(r=0.4888)。假髓乳管数与其成龄芽接树头5年产量没有相关。
This paper studies the relationship between foliar mammary duct and rubber seedling yield forecast. It was observed that the main mainspipe of the leaf was connected with the lateral mammary ducts; the number of the main mainspheres of the leaves decreased gradually from the leaf base to the tip of the leaf; the number of the lateral mainspheres decreased gradually from one end of the main veins to the leaf margin; Duct number more, and then to the leaf base and tip gradually reduced. In contrast, there was a significant and highly significant correlation between the number of lateral mammary ducts and the leaflets of the petiole and the yield of the budding tree. There was a significant correlation (r = 0.4048) between the number of small leaflet cortex ducts and the 5-year yield of their adult shoots. There was a significant correlation between the number of phloem ducts and their 5-year-old shoot biomass (r = 0.4888). The number of pseudotronal tubes was not related to the 5-year yield of its adult shoots.
