Jojoba (Simmondsia chinensis [Link] Schneider) is an important crop in desert climates. A relatively high frequency of periods of chilling and high photon flux density (PFD) in this environment makes photoinhibition likely, resulting in a reduction of assimilation capacity in overwintering leaves. This could explain the low net photosynthesis found in shoots from the field (4-6 micromoles per s...

We formulate and analyze two dynamic energy budget models, a net assimilation model with constant allocation strategy and a net production model with a 2-stage allocation strategy, with the objective of determining strategies that maximize the expected lifetime reproductive energy. The per capita death rate depends on the organism's size, as for example when the main cause of death is predation...

Individual groups of peach (Prunus persica [L.] Batsch) seedlings stressed to -17, -26 and -36 bars recovered to control levels within 1, 3, and 4 days, respectively. Stomatal resistance was significantly correlated with both leaf water potential and net photosynthesis. In seedlings stressed to -52 bars, leaf water potential and stomatal resistance recovered sooner than net photosynthesis, desp...

Abstract Introduction Appendectomy is associated with complications and negative appendicectomy. We evaluated the rate predictors of NAR in a cohort. Method Patients' data who underwent emergency appendicectomies over year was analysed. A definition NA; absence inflammatory cells appendix. The calculated using (NAR-SDC) (NAR-STC). Leucocytosis total WBC >11000/mm3, elevated CPR >5...

(Seedling growth of fifteen Brazilian tropical tree species differing in successional status). Growth of seedlings of fifteen tropical tree species representative, at the adult stage, of different successional positions, was studied under field conditions. Seedlings were grown in three treatments: full sun (FS), artificial shade imposed by neutral screens (AS) and natural shade imposed by a clo...

nineteen bread wheat genotypes were selected to examine the effect of glycine betaine (gb, 100 mm) on various photosynthetic gas exchange parameters under drought stress and to study the relationship of these parameters with non-enzymatic antioxidants. drought stress caused a significant decline in net co2 assimilation rate (pn), stomatal conductance (gs), intercellular co2 concentration (ci) a...

Abstract Introduction Negative appendicectomy (NA) is still a major issue following appendicectomy. We evaluated the rate and predictors of negative in cohort. Patients Methods Data patients who underwent emergency appendicectomies over year was collected analysed. The absence inflammation and/or other significant pathology appendix considered by standard definition. A stricter definition NA in...

predation rate is basic to any investigation of prey-predator interaction and a major component in the selection of predators for biological control. the predation rate of variegated lady beetle, hippodamia variegata (goze), fed on different densities (20, 40, 60, 80 and 100) of third instar nymphs of cotton aphid, aphis gossypii glover, was studied under laboratory conditions (25 ± 1 °c, 65 ± ...

Leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), net assimilation rate (NAR) and above ground dry matter accumulation (AGDM) of a cultivar of chickpea (Cicer arietenum) were studied with the application of potassium naphthenate (KNap) and naphthalene acetic acid (NAA) as foliar spray in 2001-2002. The growth regulators had greater influence on plants which showed compara...
