　　Ginkgo (Ginkgo biloba) is often subjected to drought during its growth season.However,little is known about the physiological mechanisms underlying changes in the photochemical activities of PSⅡ in Gingko.In this study, we analyzed changes in the fluorescence characteristics of PSⅡ in chloroplasts of mesophyll cells in drought-stressed leaves of the G.biloba cultivar Taixingdafuzhi.Five-year-old ginkgo trees were grown in pots in a greenhouse and subjected to one of four drought treatments (20, 30, 40 or 50 days without watering) and compared with control trees (0 days without watering).

酸铝复合胁迫对菊芋幼苗生长及矿质元素的影响

近年来由于农业化肥的使用及酸雨的频繁沉降，使土壤酸化加剧，大量的活性铝严重抑制了作物的生长，铝已成为酸性土壤中抑制作物生长的一个重要因素.中国南方的地带性土壤主要是红壤，遍及南方15个省区，面积占全国土地总面积的22.7％.南方地区酸雨发生的频繁，降雨量大，红壤普遍呈强酸反应(pH值约为4.0～5.5)，其富铝化程度还在不断加深，因此，铝毒被认为是南方红壤地区农作物减产的重要原因之一.改善酸性土壤

栽插苗数对超级稻‘南粳49’冠层和产量的影响

水稻高产群体一般具备三大生物学特性：有大的叶片光合强度和高的干物质积累；有强大根系，吸肥、吸水能力强；穗大粒多[1]。众多学者对水稻群体的特性及高产群体的构建进行过大量研究[2-4]，但不同品种的生长发育特性有差异，针对某一个特定品种[5]，有必要研究不同栽培措施对其群体发育特性和光合的影响，以便进一步构建高光效群体，发挥其高产、超高产潜力。
