Climate change alters the abiotic constraints faced by plants, including increasing temperature and water stress. These changes may affect flower development and production of flower rewards, thus altering plant-pollinator interactions. Here, we investigated the consequences of increased temperature and water stress on plant growth, floral biology, flower-reward production, and insect visitatio...

Consequences of drought stress in crop production systems are perhaps more deleterious than other abiotic stresses under changing climatic scenarios. Regulations of physio-biochemical responses of plants under drought stress can be used as markers for drought stress tolerance in selection and breeding. The present study was conducted to appraise the performance of three different maize hybrids ...

Need fast-acting control of surfacefeeding and soil insects? Dylox insecticide works immediately after irrigation or rainfall to control insects such as white grubs, mole crickets, sod webworms and cutworms. The fastworking product penetrates thatch up to a half-inch thick when watered properly, providing grub control within 24 hours. Under normal conditions, Dylox controls the pest and then de...

†Background and Aims One of the most striking attributes of clonal plants is their capacity for physiological integration, which enables movement of essential resources between connected ramets. This study investigated the capacity of physiological integration to buffer differences in resource availability experienced by ramets of the clonal wild strawberry plant, Fragaria vesca. Specifically, ...

Leaf growth and Anthesis-Silking Interval (ASI) are the main determinants of source and sink strengths of maize via their relations with light interception and yield, respectively. They depend on the abilities of leaves and silks to expand under fluctuating environmental conditions, so the possibility is raised that they may have a partly common genetic determinism. This possibility was tested ...

Determinate root growth is an important adaptation feature for seedling establishment in some Cactaceae. We show that seedlings of Pachycereus pringlei have primary roots with a stable determinate developmental program. How water stress affects determinate root growth and lateral root development has not been studied. Here we address this question. Root growth was analyzed in plants growing in ...

Several studies, performed mainly in pots, have shown that arbuscular mycorrhizal symbiosis can mitigate the negative effects of water stress on plant growth. No information is available about the effects of arbuscular mycorrhizal symbiosis on berseem clover growth and nitrogen (N) fixation under conditions of water shortage. A field experiment was conducted in a hilly area of inner Sicily, Ita...

(1) Background: Root traits play important roles in acclimating to water and phosphorus (P) shortages. However, the relative importance of root size efficiency under these conditions is unknown. (2) Methods: This study investigated role water- P-limited environments. Three soybean genotypes with contrasting sizes were grown tall cylindrical pots compare grain yield, density, nutrient-uptake eff...

 Net photosynthesis rate (Pn), stomatal conductance (gs) and transpiration rate (E) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (Tleaf), leaf vapor pressure deficit (VPD leaf) and photosynthetic photon flux density (PPFD) in well watered (WW), stressed (S) and recovered (R) plants. An analysis of measured data showed tha...
