In response to changes in phloem supply, adenylate demand, and oxygen status, legume nodules are known to exercise rapid (seconds to hours) physiological control over their permeability to oxygen diffusion. Diffusion models have attributed this permeability control to the reversible flow of water into or out of intercellular spaces. To test hypotheses on the mechanism of diffusion barrier contr...

Phloem girdling is used for many fruit trees to promote set and quality. Although studies showed the pomological biochemical effects of in trees, there very little information on how affects cell physiology. The current study aimed characterize leaf xylem structure, cortex division, expansion affected by trunk during phloem healing peach. experiment was carried out a two-year-old peach cv. Rich...

abstract in this study, fresh pistachio of 'ohadi' and 'akbari' cultivars expose to the uv-c radiation with a wavelength of 0, 3, 6 and 12 kj/m2, then located at temperature of 1 ± 3 degrees celsius for 45 days. properties or attributes, including weight loss, stiffness and sensory evaluation of fresh pistachio after 20 and 45 days storage were measured. results showed that pistachio nut weight...

The effects of girdling were analysed in a sessile oak (Quercus petraea Matts. Leibl.) forest with an 80-year-old coppice with standard structure in northern Spain. The study evaluated the viability of girdling as an alternative to felling trees during crown thinning. Eighty-four direct competitors of selected future crop trees were girdled by double notching and peeling. Three years after gird...

this experiment was conducted to improve the nutritive value of barley stubble for two consecutive years. after harvesting crop, at first year, a completely randomized design, with a 3 × 3 factorial experiment was conducted in which 27 plots were divided into nine treatments. the treatments including zero, 2.5 and five percent urea each with zero, three and six percent molasses were mixed with ...
