Straw Mulching Alleviates Drought Stress in Spring Maize at the Tasseling Stage: Regulation of Photosynthetic Gas Exchange and Photosystem II Photochemical Function
Although the tasseling stage is a pivotal window for drought stress in maize, the photosynthetic physiological mechanism by which straw mulching compensates for drought-induced impairment relative to conventional rain-fed practice remains unclear. In this study, a two-factor randomized block experiment was conducted wi...
