Drought can cause large yield losses of rapeseed ( Brassica napus L.), particularly during the flowering stage. Effective methods crop management are required to improve resistance drought. Film antitranspirants (AT), as an effective method management, reduce water loss by forming a waterproof layer block stomata mechanically. In our study, three pot experiments were conducted in glasshouse at ...

The canopy temperature is a promising methodology for deficit irrigation scheduling. This measurement used to calculate the crop water stress index (CWSI), which needs estimation of non-water baseline (NWSB). In olive orchards, NWSB changed at different times day and throughout season. aim this work was evaluate simplified estimating allow reducing costs facilitate CWSI estimation. experiment p...

We monitored sap flow and estimated diurnal changes in transpiration rates of two trembling aspen (Populus tremuloides Michx.) stands, located in the southern boreal forest and aspen parkland of Saskatchewan, Canada. In both stands during the peak growing season (June and July), sap flow during the day (0700-1700 h local time) increased linearly with vapor pressure deficit (VPD) from 0 to about...

AIM To observe the regulatory effect of Chinese herbal medicine on peritoneal lymphatic stomata and its significance in treating ascites in liver fibrosis model mice. METHODS Two Chinese herbal composite prescriptions were used separately to treat the carbon tetrachloride-induced mouse model of liver fibrosis. The histo-pathologic changes of the liver sections (HE and VG stainings) were obser...

Soil salinity is a pending threat to global agricultural sustainability and food security. The natural means of alleviating this stress have become the major concern as which methods, mechanisms, organisms be used. Soil-borne fungi Trichoderma has proven alleviate in plants. This review aimed shed light on roles mechanisms some species response salt other merits plant growth development. Detail...

To identify effective light spectra for increasing the productivity of Panax ginseng, we conducted experiments in a controlled environment using hydroponic cultivation system plant factory. We investigated effect single LEDs (red, blue, and yellow) mixed (red + blue red white). The relationships between four yellow, white) physiological responses (net photosynthetic rate, stomata conductance, t...

Motivated by studies suggesting that the stomata of ferns and lycophytes do not conform to the standard active abscisic acid (ABA) -mediated stomatal control model, we examined stomatal behavior in a conifer species (Metasequoia glyptostroboides) that is phylogenetically midway between the fern and angiosperm clades. Similar to ferns, daytime stomatal closure in response to moderate water stres...

During photosynthesis, CO2 moves from the atmosphere (C(a)) surrounding the leaf to the sub-stomatal internal cavities (C(i)) through stomata, and from there to the site of carboxylation inside the chloroplast stroma (C(c)) through the leaf mesophyll. The latter CO2 diffusion component is called mesophyll conductance (g(m)), and can be divided in at least three components, that is, conductance ...
