Jute (Corchorus capsularis L.) plants were grown in sandculture with Hoagland's nutrient solution containing five levels (1/4 N, 1/2 N, 1 N, 2 N, 4 N) of ammonium nitrogen or nitrate nitrogen. An investigation was made on the effects of various nitrogen levels and forms on photosynthesis, photorespiration and nitrate reduction in jute plants. The results as the following:

不同硝态氮水平对黄麻叶片的光合强度、光呼吸强度、乙醇酸氧化酶及硝酸还原酶均产生显著的影响:除了光合强度以外,其余三者均随氮水平的增高而显著地增高;在低至正常氮水平范围内(1/4~1N),光合强度随氮水平的增高而增高,但在高硝态氮水平范围内(2~4N),光合强度有随氮水平的增高而略为下降的趋势。氨态氮水平的增高对光合强度、光呼吸强度、乙醇酸氧化酶活性也有影响:三者均随氮水平的增高而有所提高,但不如硝态氮处理的那样明显。在用氨态氮处理的植株中测不出硝酸还原酶的活性。用光呼吸抑制剂亚硫酸氢钠,α-羟基-2-吡啶甲烷磺酸(HPMS)及异烟肼(INH)真空渗入黄麻叶圆片以抑制光呼吸时,硝酸还原亦同时部分受抑。因此认为在乙醇酸途经中的甘氨酸氧化脱羧反应可能为硝酸还原提供还原剂NADH。

用氧电极研究叶圆片断光后的耗氧变化,观察到断光后急骤耗氧(rapid postilluminationoxygen consumption RPIOC)现象。在不更换反应液的情况下,随着连续测定次数的增加,烟草叶圆片和番薯叶肉细胞的RPIOC增强。烟草、水稻、番薯、木瓜、黄瓜的叶圆片和番薯叶肉细胞表现出RPIOC,而高粱、甘蔗和玉米则没有这种现象。烟草叶国片的RPIOC随以下因素变化而增强:氧浓度从0.077mmol/L 气相O_27%)增加到 0.230 mmol/L(气相O_2 21%)、光强从111W/m~2增加到350W/m~2、温度从20℃增加到40℃,NaHCO_3(pH7.8)浓度从1 mmol/L(气相CO_2 1188ppm)降低到0.05mmol/L(气相CO_260 ppm)。0.4 mmol/L的HPMS完全抑制烟草叶圆片的RPIOC;10mmol/L的环氧丙酸抑制烟草叶圆片的RPIOC 57.8%。因此认为RPIOC是光呼吸的另一种形式的表现,它对环境因子的变化与已知的影响光呼吸的因子具有一致的反应。
