Within the context of climate change, water scarcity is the major constraint to the viability of many crops. Thus, it is necessary to develop strategies for sustainable water management, and introduce alternative crops to sustain the viability of agro-ecosystems. The main objective of this work was to assess the performance of hemp (Cannabis sativa L.) subjected to different plant densities and...

The tropical conifer Callitris intratropica (Cupressaceae) produces clear annual growth rings, and has been shown to be potentially useful for understanding past climate variability in northern Australia. As climate patterns in this region become less predictable, an understanding of plant responses to different weather patterns is of importance. In this paper, we examine tree water relations u...

The isotopic composition of tree-ring cellulose was obtained over a two-year period from small diameter, riparian zone trees along an elevational transect in Big Cottonwood Canyon, Utah, USA to test for a possible temperature dependence of net biological fractionation during cellulose synthesis. The isotope ratios of stream water varied by only 3.6% and 0.2% in deltaD and delta18O, respectively...

Phenological synchronicity of different tree parts and habitats can provide valuable insights into the physiological relationships regulatory factors phenologies. The earlywood (EW) to latewood (LW) transition xylem is a critical process closely related key functions processes trees. This study investigated phenology phase EW–LW in branches stems Smith fir (Abies forrestii var. smithii Viguié &...

Research Highlights: A small, long-term decrease in the water availability a Mediterranean holm oak forest elicited strong effects on tree stem growth, mortality, and species composition, which led to changes ecosystem function service provision. Background Objectives: Many ecosystems are increasingly challenged by stress conditions under climate change. These new environmental constraints may ...

in this study, long-term trends and abrupt changes of hydro-climatic variables was investigated in the observed period 1971-2000 for aidoghmoush basin using mann-kendall nonparametric test and cumulative curve of climatic variables-runoff, respectively. results show decrease trends for rainfall and runoff and increase trend for temperature by the mann-kendall test with a confidence level of 99%...

This study was carried out to evaluate F1 single cross-maize hybrids in four crop growing seasons (2010-2012). Morphological traits and physiological parameters of twelve maize hybrids were evaluated (i) to construct seed yield equation and (ii) to determine grain yield attributing traits of well-performing maize genotype using a previously unexplored method of two-way hierarchical clustering. ...

Leucaena leucocephala is fast growing leguminous tree species, acclimatized to variety of soil and climatic conditions. It is widely used for pulp production in India. Pulp mainly consists of cellulose, which is a simple polymer of unbranched β-1, 4-linked glucan chains. The polymerization of glucose residues into a β-1, 4-linked backbone is catalysed by the enzyme cellulose synthase (CesA). He...
