, 2012 以水稻、高粱和玉米为研究对象,考察了微囊藻毒素对受试作物的毒性差异,研究了不同浓度MC对萌发及萌发初期生长发育的影响,不同灌溉时期对受试作物生长发育的影响,检测指标包括发芽率、株高、鲜重、叶绿素、根系活力等。结果表明,受试作物对微囊藻毒素毒性并不一致,水稻发芽率受到明显抑制,高粱发芽率基本不受影响,玉米出现了低浓度促进、高浓度抑制的现象;MC对水滔、高粱和玉米的光合作用、株高和鲜重没有抑制作用,反而有一定的促进效果;不同灌溉时间条件下的研究结果表明,萌发前对高粱和玉米染毒会明显抑制植株根系活力 ...

Effects of Restricted Rhizosphere on Various Growth Characters of Paddy Rice Plants (Oryza sativa L.) : 3. Isolation of Roots Systems and Plant Growth [PDF]
, 1988 本実験は水稲根系の株内相互作用を解明するため, 株内の個体の根系を隔離した場合と, 根系が交錯した場合(標準区)における, 水稲の諸形質の差異について検討した。根系が隔離された条件のもとでは, 幼穂形成期の株当り全乾物重は根圏域の大きさと関係なく, 4本植で増加し8本植では減少した。出穂期にはすべての区で増加したが, その増加量はL区で最も大きかった。しかし, 成熟期になると各区とも増加量は著しく小さかった。各生育段階におけるT-R率は根系隔離によって低下した ...

Greenhouse gas emissions from croplands of China [PDF]
, 2003 China possesses cropland of 1.33 million km 2. Cultivation of the cropland not only altered the biogeochemical cycles of carbon (C) and nitrogen (N) in the agroecosystems but also affected global climate.

Integrative Conservation, EarlyView.Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Influence of Root Secretion Flavonoids on the Biogeochemistry Behavior of Cadmium in Avicennia marina (Forsk.) Vierh Rhizosphere [PDF]
, 2015 红树林生态系统主要分布于热带和亚热带的海岸潮间带，其具有独特的生态学和生物学特性，为污染物的吸附治理提供了最佳场所。然而，近年来，随着工业化、城市化和地区经济的快速发展，导致大量生活污水和工业废水流向红树林湿地，使得红树林生态系统面临越来越严重的重金属污染，从而使得滨海湿地面临着日益严峻的重金属污染。进入红树林湿地的污染物最先在红树植物根际区进行一系列形态转化等过程，而后被植物吸收累积。因此，红树林根际区重金属化学行为已经成为近年来污染生态学的研究热点。 类黄酮是植物体内广泛存在的一类重要次生代谢产物 ...

PLANTS, PEOPLE, PLANET, EarlyView.Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased
