Objective: In order to study the effect of different concentrations of IBA hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in Jiroft, Iran. Methods: a split-plot experiment was conducted on the basis of a Randomized Complete Block Design in which hardwood cuttings of one-year-old olive plants cv. Manzanilla with the diameter of 0.7-1 cm were used. The main...

—We quantified changes in capture rates and sex ratios from May to Sept. for eight species of bats, derived from 8 y of extensive mist netting in forests of the Ouachita Mountains, Arkansas. Our primary goal was to determine patterns of relative abundance for each species of bat captured over forest streams and to determine if these patterns were similar to patterns of abundance found in other ...

abstract more than %90 of natural silk in world is produced by means of mulberry silkworm (bombyx mori l.). therefore, it is important that we recognize and collect mulberry varieties which have high quantity and quality leaf performance. for this purpose, an experiment was conducted with five mulberry varieties (kenmochi, kairyonase, ichinose, shinichinose and local varieties) during two seaso...

During winter, trees have to cope with harsh conditions, including extreme freeze-thaw stress. This study focused on ice nucleation and propagation, related water shifts and xylem cavitation, as well as cell damage and was based on in situ monitoring of xylem (thermocouples) and surface temperatures (infrared imaging), ultrasonic emissions, and dendrometer analysis. Field experiments during lat...

This study evaluated seasonal differences (spring and summer) in the processing of Typhu ungustifolia leaves in a Mediterranean river. The experiment extended over 120 days, corresponding to six sampling periods for each experiment. Leaves (5 g) were placed in 0.5 cm mesh-size bags. After recovering the sample, macroinvertebrates inside the leaf bags were retrieved and the leaves preserved by f...

zayanderoud basin is one of the important agricultural areas in country level because of climatic variety and resuscitative water of zayanderoud river. since frost phenomenon especially late spring frost incurs great damages on fruit trees and agricultural products of this region, it is necfessary to study frost in this basin.in this research, the intensity of frost during cold period and sprin...

The volatile organic compound (VOC) emission rates of Scots pine (Pinus sylvestris L.) were measured from trees growing in a natural forest environment at two locations in Finland. The observed total VOC emission rates varied between 21 and 874 ng g−1 h−1 and 268 and 1670 ng g−1 h−1 in southern and northern Finland, respectively. A clear seasonal cycle was detected with high emission rates in e...
