Alterations in Chloroplast Thylakoids during an in Vitro Freeze-Thaw Cycle.

abstract：:In maize (Zea mays L., cv Contessa), nitrogen (NO(3) (-)) limitation resulted in a reduction in shoot growth and photosynthetic capacity and in an increase in the leaf zeaxanthin contents. Nitrogen deficiency had only a small effect on the quantum yield of CO(2) assimilation but a large effect on the light-saturated r...
