莫斯科大学建成世界上最大的校藏数字化植物标本库“诺亚方舟”
莫斯科大学 校藏数字化植物标本库 诺亚方舟
2017/2/20
莫斯科大学的研究人员在俄罗斯科学基金资助的“诺亚方舟”项目框架下，对莫大生物系植物标本库进行逐一扫描，建成世界上最大的植物图像扫描标本库之一。该校储存植物标本数字化工作始于2015年春季，用一年半时间完成了对东欧、西伯利亚和远东、克里米亚、高加索、蒙古、非洲和南亚等国家地区大量代表性植物群系的扫描工作。新建的数据库是俄罗斯最大的植物多样性与繁殖信息库，不仅供专业人士使用，也可为想更多了解植物方面知...

乌克兰科学家研发出用于确定植物状态的装置
乌克兰科学家 植物状态 装置
2016/11/14
农作物高产得益于良好的生长环境，温度的剧烈变化、湿度过高或过低、有害工业废气污染都会影响植物的生长。监测植物在这些因素变化情况下的生长状态很重要，以便进一步采取灌溉、施肥或除草的措施。然而，植物自身内部变化并不立即从外观表现出来。乌克兰国家科学院控制论研究所的科学家们研发出一种名为“Флоратест”的特殊装置，可以精确确定植物在光合作用过程中的状态。

叶子用量子效应增强光合作用
叶子用量子效应 增强 光合作用
2016/11/1
美国《大众科学》2016年10月26日在线发表的文章显示，一种喜阴植物通过自己蓝晕色叶子，利用量子力学原理使光合作用高效进行，从而适应了极度弱光的环境条件。光合作用被认为是地球拥有生命的标志性反应，植物在进行光合作用时可获取大量太阳光照，叶绿体将收集的阳光转化为化学能。研究人员发现，在马来西亚茂密的热带雨林中生存的名为孔雀秋海棠的植物，因表层有不同寻常的叶绿体——虹光质体而拥有斑斓的蓝色叶子。
As we push the limits of agriculture to feed more people in a warmer world, we do not understand how plants sense temperature.In a surprising turn of events, scientists at the University of Buenos Air...

新叶片加速亚马逊雨林光合作用
新叶片 亚马逊雨林 光合作用
2016/2/29
尽管亚马逊雨林四季常青，但其光合作用能力却是季节性的。在干旱季节，研究人员注意到它们吸收的二氧化碳量会神秘地上升。然而这一现象背后的原因却不清楚，很多科学家认为可能是额外的阳光或是干旱导致植物的光合作用能力更强。
