Eight red maple (Acer rubrum L.) provenances, four each from wet and dry sites, were grown under the same conditions and their physiological responses to soil water availability investigated. Under well-watered conditions, seedlings of wet-site provenances grew faster and had consistently higher net photosynthesis, leaf conductance, maximum carboxylation rate, maximum rate of coupled photosynth...

We tested the hypothesis that intermittent (lammas) shoot growth in Douglas-fir (Pseudotsuga menziesii var menziesii (Mirb.) Franco) seedlings from dry regions of southwest Oregon is adaptively significant. Seedlings from open-pollinated families (160 total) from two inland (dry) and two coastal (wet) sources were grown under either well-watered or intermittent drought conditions (temporary dro...

Plants acclimate to drought optimizing the trade-off between biomass production and water loss while ensuring their survival and reproduction. Plants also modify their growth or phenology as complementary strategies in response to stress. Despite evidence of an interaction between flowering time and plant growth response to environmental stresses, this interaction in response to drought is unde...

BACKGROUND Drought stress is one of the most important abiotic stresses and the main constraint to rice agriculture. MicroRNA-mediated post-transcriptional gene regulation is one of the ways to establish drought stress tolerance in plants. MiRNAs are 20-24-nt regulatory RNAs that play an important role in regulating plant gene expression upon exposure to biotic and abiotic stresses. METHODOLO...

Recurrent drought and late blight disease are the major factors limiting potato productivity in the northwest Ethiopian highlands. Incorporating drought tolerance and late blight resistance in the same genotypes will enable the development of cultivars with high and stable yield potential under erratic rainfall conditions. The objectives of this study were to assess combining ability effects an...

We investigated the impact of drought and arbuscular mycorrhizal (AM) fungi on the morphological structure and physiological function of shoots and roots of male and female seedlings of the dioecious plant Populus cathayana Rehder. Pot-grown seedlings were subjected to well watered or water-limiting conditions (drought) and were grown in soil that was either inoculated or not inoculated with th...

Global agrobiodiversity is threatened by the replacement of traditional, locally adapted crop varieties with high-yielding and hybrid during past 60 years, resulting in associated losses crop, variety, allele diversity. Locally adapted, traditional are known to perform equal or even better under environmental stress conditions be more resilient unstable cultivation environments. Therefore, Euro...

The objective of this study was to determine the effect drought stress on neutral detergent fiber (NDF) and lignin (LIG) concentrations in vitro dry matter digestibility (IVDMD) (IVNDFD) leaf blades stem internodes corn for silage. Eight plots were blocked (i.e., 4 blocks) randomly subjected a watered (W) or non-watered (NW) treatment. Within each block, split into 7 sub-plots, which 1 hybrids ...

Microplastics in soils have become an important threat for terrestrial systems as they may potentially alter the geochemical/biophysical soil environment and can interact with drought. As microplastics affect water content, this could exacerbate well‐known negative effects of drought on ecosystem functionality. Thus, functions including litter decomposition, aggregation or those related nutrien...
