1) phosphorus deficiency
缺磷
1.
unshiu increased in the sequence of phosphorus deficiency blaze group(-P900),phosphorus deficiency mid-blaze group(-P600),an.
结果表明:饱和脉冲光作用前后,缺磷强光组(-P900)、缺磷中强光组(-P600)和缺磷弱光组(-P100)的叶温差(△t)依次升高,并且培养光强越弱,处理时间越长,升高幅度越大;而供磷强光组(+P900)、供磷中强光组(+P600)和供磷弱光组(+P100)之间,△t无明显差异;用二硫苏糖醇(DTT)处理后,无论缺磷与否,各处理组之间△t差异显著;△t的日变化随光强的升高而增大;各组叶绿素a、叶绿素b和类胡萝卜素含量均随培养光强的升高而下降,而蒸腾速率、气孔导度和胞间CO2浓度差异不大;说明温州蜜柑叶温差与光强、磷水平、DTT处理和缺磷胁迫时间有关。
2.
The leaves of sample under phosphorus deficiency changed dark green.
缺氮处理25d的矮牵牛植株叶色淡绿,下部叶片发黄,叶柄短而纤弱,叶绿素含量较对照植株叶绿素含量减少20%左右;缺磷植株叶片呈暗绿色,部分植株的茎部和叶片出现紫红色,叶子小而狭,叶柄短而纤弱;缺钾植株叶子有缺绿斑和坏死斑出现,叶子变厚,叶柄变短。
2) P deficiency
缺磷
1.
Response of plasma membrane H~+-ATPase of rice roots to the P deficiency;

2.
P is an important nutrient element in plant,and P deficiency is one of the major factors limiting crop production.
采用石英砂培养方法并去除或保留分蘖,研究旗叶期缺磷对大穗型小麦CA9325和多穗型晋麦2号(JM2)生长后期旗叶光合和蒸腾速率、干物质和磷在体内分配以及最终产量的影响。
3.
Effects of phosphorus deficiency on alternative respiratory pathway and its relation with O2- production were investigated in two lines of suspension-cultured tobacco cells which have different tolerances to P deficiency.
用两个耐低磷能力差异显著的烟草悬浮细胞系,研究了缺磷胁迫对交替呼吸途径的影响及其与活性氧积累的关系。
3) phosphate deficiency
缺磷
1.
Response of plasma membrane H~+-ATPase activity in roots of oil rape(Brassica napus L.)to phosphate deficiency;
