| 1 | 不同叶龄拟南芥荧光参数分析及对强光的响应显示文摘采用叶绿素荧光图像分析系统,研究了野生型拟南芥(Wild Arabidopsis thaliana)Col-0不同叶龄叶片的荧光参数变化及对强光的响应。结果表明,随叶片趋于成熟或衰老,20 min暗适应的最大PSⅡ光化学量子效率(Fv/Fm),稳定作用光下的PSⅡ有效和实际光化学效率(Fv′/Fm′和ΦPSⅡ)以及光化学猝灭系数(q P)均呈降低趋势,而非光化学猝灭系数(NPQ)增加;但短期5 d的处理期间其变化都不明显。与低光强相比,强光处理时Fv/Fm,ΦPSⅡ,Fv′/Fm′和q P呈降低趋势而NPQ明显升高。说明不同发育阶段的叶片具有明显差异的光化学反应特性,强光下光抑制现象明显;NPQ增加说明拟南芥能通过非辐射的热能耗散途径消耗过多的激发能,从而能避免光合机构的继续伤害。 | 师生波 Neil Baker Tracy Lawson 张德罡 | 2011 | 草原与草坪2011，31，4： | 4 |

| 4 | Feeding the world: impacts of elevated [CO_(2)] on nutrient content of greenhouse grown fruit crops and options for future yield gains显示文摘Several long-term studies have provided strong support demonstrating that growing crops under elevated[CO_(2)]can increase photosynthesis and result in an increase in yield,flavour and nutritional content(including but not limited to Vitamins C,E and pro-vitamin A).In the case of tomato,increases in yield by as much as 80%are observed when plants are cultivated at 1000 ppm[CO_(2)],which is consistent with current commercial greenhouse productionmethods in the tomato fruit industry.These results provide a clear demonstration of the potential for elevating[CO_(2)]for improving yield and quality in greenhouse crops.The major focus of this review is to bring together 50 years of observations evaluating the impact of elevated[CO_(2)]on fruit yield and fruit nutritional quality.In the final section,we consider the need to engineer improvements to photosynthesis and nitrogen assimilation to allow plants to take greater advantage of elevated CO_(2) growth conditions. | Nicholas H.Doddrell Tracy Lawson Christine A.Raines Carol Wagstaff Andrew J.Simkin | 2023 | Horticulture Research2023，10，4： | 0 |
