    Insight into the molecular mechanisms of leaf coloration in Cymbidium ensifolium
  9. 2589
    “…The results show that zero discharge treatment did not change plant height, stem diameter, internode length, leaf area, net photosynthetic rate (P(n)), stomatal conductance (G(s)), intercellular CO(2) concentration (C(i)), transpiration rate (T(r)), and leaf relative chlorophyll content on the most measurement days. Only P(n) and relative chlorophyll content were significantly reduced after 16 days of treatment but soon recovered over time. …”
