5) P deficiency
缺磷
1.
Response of plasma membrane H~+-ATPase of rice roots to the P deficiency;
水稻根系细胞膜H~+-ATPase对缺磷的反应
2.

6) 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。
