中文摘要:

因为有限测量方法,植物利用的酸式碳酸盐的数量通常被忽略。因此,这研究确定了无机的碳的光合的吸收(由植物的公司 2 和 HCO 3) 。网光合的公司2吸收( P N ),公司2和酸式碳酸盐的光合的吸收( P N ),增加的叶区域的比例( f LA )和稳定的碳同位素作文( 13 C ) Orychophragmus violaceus ( Ov )并且在三酸式碳酸盐下面的 Brassica juncea ( Bj )铺平( 5 , 10 和 15 ?公里 NaHCO 3)被检验在 P N , P N 和 f LA 。P N , 不 P N, 随着 f LA 。而且,外长的酸式碳酸盐的比例和 Ov 利用的全部的酸式碳酸盐(包括的外长的酸式碳酸盐和溶解公司 2-generated 酸式碳酸盐)是 2.27 ?%并且 5.28 ?在 5 点的%?公里酸式碳酸盐, 7.06 ?%并且 13.28 ?在 10 点的%?公里酸式碳酸盐,并且 8.55 ?%并且 17.31 ?在 15 点的%?公里酸式碳酸盐分别地。同时,外长的酸式碳酸盐的比例和 Bj 利用的全部的酸式碳酸盐是 1.77 ?% 并且 3.28 ? 在 5 点的 %? 公里酸式碳酸盐, 2.11 ?% 并且 3.10 ? 在 10 点的 %? 公里酸式碳酸盐,并且 2.36 ?% 并且 3.09 ? 在 15 点的 %? 公里酸式碳酸盐分别地。因此,溶解公司 2-generated 酸式碳酸盐和外长的酸式碳酸盐是为植物的无机的碳的重要来源。

英文摘要:

The amount of bicarbonate utilised by plants is usually ignored because of limited measurement methods. Accordingly, this study quantified the photosynthetic assimilation of inorganic carbon (COe and HCO3-) by plants. The net photosynthetic COa assimilation (PN), the photosynthetic assimilation of CO2 and bicarbonate (PN'), the proportion of increased leaf area (lEA) and the stable carbon isotope composition (δ13C) of Orychophragmus violaceus (Ov) and Brassica juncea (B j) under three bicarbonate levels (5, 10 and 15 mm NaHCO3) were examined to determine the relationship among PN, PN' and fLA. PN', not PN, changed synchronously with fLA. Moreover, the proportions of exogenous bicarbonate and total bicarbonate (including exogenous bicarbonate and dissolved CO2-generated bicarbonate) utilised by Ov were 2.27 % and 5.28 % at 5 mm bicarbonate, 7.06 % and 13.28 % at 10 mm bicarbonate, and 8.55 % and 17.31% at 15 mm bicarbonate, respectively. Meanwhile, the propor- tions of exogenous bicarbonate and total bicarbonate uti- lised by Bj were 1.77 % and 3.28 % at 5 mm bicarbonate, 2.11% and 3.10 % at 10 mm bicarbonate, and 2.36 % and 3.09 % at 15 mm bicarbonate, respectively. Therefore, the dissolved CO2-generated bicarbonate and exogenous bicarbonate are important sources of inorganic carbon for plants.
