Abstract:
... Water potential (Ψw) is a fundamental thermodynamic parameter that describes the activity of water and is a key metric of plant water status. In this paper, we evaluate the continuous measurement of water potential in grapevine trunks using a novel in situ sensor known as a ‘microtensiometer’ under field conditions in two South Australian vineyards. We characterised the seasonal and diurnal dynami ...

Abstract:
... PREMISE: Epiphytes are abundant in ecosystems such as tropical montane cloud forests where low‐lying clouds are often in contact with vegetation. Climate projections for these regions include more variability in rainfall and an increase in cloud base heights, which would lead to drier conditions in the soil and atmosphere. While recent studies have examined the effects of drought on epiphytic wate ...

Abstract:
... The interaction between cytokinin, auxin and GA controlled in vitro shoot multiplication in paulownia was influenced by a medium water potential (Ψ) modulation, where it was modulated using different textures or strengths of MS medium, media of different types (MS, WPM, SH and B5) or NaCl incorporation. The interaction between 2 mg/L BAP and 0.1 mg/L NAA expressed the highest shoot number on each ...

Abstract:
... AIM: Our understanding of species’ responses to climate depends on choosing the scale for the analysis. Processes driving physiological adaptation that occur at the small spatial scales most relevant to animals may be masked in correlations between organismal traits and broad‐scale climatologies, but the extent to which this undermines our understanding of the macroevolution of physiological trait ...

Abstract:
... Soil drying is a limiting factor for crop production worldwide. Yet, it is not clear how soil drying impacts water uptake across different soils, species, and root phenotypes. Here we ask (1) what root phenotypes improve the water use from drying soils? and (2) what root hydraulic properties impact water flow across the soil–plant continuum? The main objective is to propose a hydraulic framework t ...

Abstract:
... A distinct midday to afternoon (midday) reduction of leaf photosynthetic rate (A ₙ) occurred in rice, even under well-irrigated conditions on a clear day, but not in green gram. No significant differences between species in leaf water potential (Ψₗₑₐf) or plant resistance to water transport during daytime were found. From the pressure–volume curves, it was revealed that rice leaves had a larger bu ...
