npq的音标

Exogenous Spd decreased 1-qP/ qN, NPQ and DEPS in leaves of cucumber seedlings during hypoxia stress, showing that exogenous Spd did not alleviate photo-inhibition of cucumber seedlings by xanthophyll cycle through dissipation excess energy under hypoxia stress.

外源Spd降低了低氧胁迫下黄瓜植株的1-qP/qN，同时也降低了NPQ和DEPS，说明Spd并不是通过增强叶黄素循环来耗散过剩光能从而缓解光抑制。

At low temperature and low irradiance, NPQ of grafted plants ascended evidently. It indicated that NPQ could effectively dissipate a portion of energy.

低温弱光胁迫下，黄瓜嫁接苗NPQ明显升高，说明NPQ有效地耗散了部分能量。
