Water use efficiency (WUE) is a key physiological trait in studying plant carbon and water relations. However, the determinants of WUE across a large geographical scale are not always clear, limiting our capacity to predict WUE in response to future global climate change. We propose that tree WUE...

The higher-level phylogeny of Pentatomomorpha, the second largest infraorder of true bugs (Hemiptera: Heteroptera), which includes many important agriculture and forestry pests, has been debated for decades. To investigate the phylogeny and evolutionary history of Pentatomomorpha, we assembled new...

The objective is to study the effects of different calcium concentrations on growth, photosynthetic parameters, chlorophyll fluorescence parameters. water-use efficiency and calcium content of Fraxinus mandshurica leaves. We used annual F. mandshurica that have similar status as test materials,...

Objective: The aim of this study was to investigate the internal physiological mechanisms of Hemiptelea davidii adapting to different soil water environments by comparing the effect of microenvironments(interdune and upperdune) with different soil water conditions on the characteristics of xylem...

As the main component of snowmelt agents, NaCl is widely used in northern winters and significantly impacts the expected growth of garden plants in north China. Salix matsudana is also faced with salt stress caused by snowmelt, which seriously affects its development as the main tree species in the ...

Light is not only a very important source of energy for the normal growth and development of plants, but also a regulator of many development and metabolic processes. The mechanism of plant growth and development under low light conditions is an important scientific question. With the promulgation...

A remarkable feature of Mimosa pudica is its ability to deform in response to certain external stimuli. Here, a two-dimensional transient bio-chemo-electro-mechanical model of the rapid movement of the main pulvinus of Mimosa pudica is developed. Based on the laws of mass and momentum conservation, ...

As a crucial element for plants, calcium (Ca) is involved in photosynthesis and nutrient absorption, and affects the growth of plants. Poplar is an important economic forest and shelter forest species in China. However, the optimum calcium concentration for its growth is still unclear. Herein, we...

With three varieties of Poa pratensis L., 'Blue chip', 'Merit' and 'Park', in urban landscape of north, after the stress of PEG (6000), the experiment was conducted to measure the chlorophyll content, MDA content, soluble protein content and the dynamic changes of the leaf relative water content in ...

Objective: The affinity and genetic diversity of the collected Bauhinia variegata germplasm resources were analyzed. Method: 15 B. variegata individuals were systematically studied by ISSR-PCR method. [Result] A total of 150 clear loci were obtained in the ISSR experiment, of which 145 loci were...
