Changes in water-soluble carbohydrates were examined in the leaves of the resurrection plant Xerophyta viscosa under conditions of water deficit. Sucrose and raffinose family oligosaccharides (RFOs), particularly raffinose, increased under these conditions, with the highest concentrations evident at 5% relative water content [RWC; 23.5 mg g(-1) dry weight (DW) and 17.7 mg g(-1) DW, respectively...

Despite considerable investigations of diurnal water use characteristics in different plant functional groups, the research on daily water use strategies of woody bamboo grasses remains lacking. We studied the daily water use and gas exchange of Sinarundinaria nitida (Mitford) Nakai, an abundant subtropical bamboo species in Southwest China. We found that the stem relative water content (RWC) a...

in order to evaluate the physiological indices in relation to the screening of spring safflower genotypes for drought tolerance and productivity, seed and oil yields and yield components were measured for five genotypes including local arak, local esfahan, sina, kh23 – 57 and goldasht. the study was conducted in a loam soil in east azarbaijan, iran, during three successive years (2005-2007)...

objective:investigating the microbes and interactions of the beneficial symbiotic relationships between the components of the system ecology in the food chains and life cycles is one of the modern sustainable agriculture topics. in this regard, to evaluate the effects of bacteria and vermicompost on morphological characteristics and yield of soybean an experiment was conducted as split plot in ...

Emissions from wood burning for heating in secondary homes or cabins is an important part the development of high-resolution emissions specific areas. Norway used as case study 20% national consumption occurs cabins. Our first shows a method to estimate based on traffic data derive cabin occupancy, which combined with need allows spatial and temporal distribution emissions. The combination resi...

Aim. Drought is one of the most harmful abiotic stresses limiting crop productivity. We study ability photosynthetic apparatus winter wheat varieties differing in their tolerance to acclimate moderate drought stress under pot experiment. Methods. Dynamics relative water content (RWC), chlorophyll content, CO2 assimilation rate (Pn), activity antioxidant enzymes chloroplasts flag leaf drought-to...

While graph neural networks (GNNs) have achieved notable success in various mining tasks, conventional GNNs only model the pairwise correlation 1-hop neighbors without considering long-term relations and high-order patterns, thus limiting their performances. Recently, several works addressed these issues by exploring motif, i.e., frequent subgraphs. However, methods usually require an unaccepta...

This experiment aimed to determine the adaptability of four biodiesel-producing plants gold mine wastewater based on morpho-physiological properties. Four species namely jatropha (Jatropha curcas), castor bean (Ricinus communis), wild candlenut (Reutealis trisperma) and bead tree (Melia azedarach) were grown in water culture using Hoagland solution for 2 weeks then treated with mining at 0% (co...

Objectives—Genitourinary tract samples are required to investigate male HIV-1 infectivity. Because semen collection is often impractical, we evaluated the acceptability, feasibility, and validity of post-prostatic massage fluid/urine (post-PMF/U) for studying male genitourinary HIV-1 shedding. Methods—HIV-1-seropositive men were evaluated after 48 hours of sexual abstinence. At each visit, a cl...

Osmotic and turgor adjustment in roots, shoots, and whole sporophytes of a NaCI-tolerant mutant and a NaCI-sensitive wildtype strain of the fern Ceratopteris richardii Brongn. were charactenzed following exposure to 60 millimolar NaCI, using a psychrometric approach to pressure-volume analysis. Water potential components of whole plants and shoots at full or ambient hydration were similar betwe...
