Flower structure, attractants, breeding system, and visitors were studied in Aspidosperma quebracho-blanco, a South American mass-flowering tree with simple moth-pollinated flowers and without floral reward. Flowers are protandrous, having ...
The Effects of Temperature and Seasonal Change on the Germination of Two Salt Marsh Species, Atriplex prostrata and Salicornia europaea, along a Salinity Gradient [0.03%]
盐度梯度下温度和季节变化对两种盐沼植物(Atriplex prostrata 和Salicornia europaea)发芽率的影响

The plasma membrane-associated NADH oxidase (NOX) of spinach leaf disks demonstrates a regular periodicity of 24.3+/-0.5 min (NADH = reduced nicotinamide adenine dinucleotide). Within a single population of plants, all exhibited a similar p...
Photosystem-II Activity Is Decreased by Yellowing of Barley Primary Leaves during Growth in Elevated Carbon Dioxide [0.03%]
二氧化碳浓度升高抑制了大麦基叶类黄素的形成及光系统II活性

Two sites exist for endocarp dehiscence (shell split) in the pistachio nut (Pistacia vera L., Anacardiaceae). Longitudinal dehiscence occurs along lines of cells that have highly lignified, interlocking walls and are differentiated from cel...
Factors Intrinsic to the Axillary Bud Determine Topophysic Effects on Bud and Shoot Growth and Flower Development in Rosa hybrida [0.03%]
影响月季腋芽生长和花发育的内源性因素及其与枝条力学状态的关系研究

N Bredmose
Topophysis (the influence of the position of axillary buds along the shoot on bud and shoot growth, fresh biomass accumulation, and flower development) were studied in Rosa hybrida L. Single-node cuttings with five-leaflet leaves were excis...
