据《园艺学报》2015年第42期《“赤霞珠”葡萄~(13)C和~(15)N吸收、分配特性的初步研究》(作者刘光春)报道,以6年生果实膨大后期“赤霞珠”葡萄为试材,运用~(13)C和~(15)N标记技术,分别标记不同部位和节位的枝条叶片,研究碳氮营养吸收分配规律。结果表明,标记近主干和远主干枝条叶片,叶片合成的光合产物和吸收的氮素营养在近主干和远主干枝条之间不相互转运,近
According to “Horticulture” 2015 42 “” Cabernet Sauvignon “grape ~ (13) C and ~ (15) N absorption and distribution characteristics of the preliminary study (author Liu Guangchun) reported that the 6-year-old fruit enlargement The ”Cabernet Sauvignon" grapes were used as experimental materials. The shoots of leaves with different parts and nodes were marked with ~ (13) C and ~ (15) N markers to study the absorption and distribution of carbon and nitrogen. The results showed that the photosynthetic products and nitrogen uptake of leaves near the main trunk and distal trunk branches did not translocate to each other near the main trunk and distal trunk branches
