Background & Aim: Strawberry (Fragaria vesca L.) is a plant belonging to the Rosaceae family with medicinal properties, including antioxidant activity. The present study aimed at investigating the antioxidant properties of strawberry. Experimental method: To examine the antioxidant effect, fruit extracts at two phonological stages of growth (ripe and unripe strawberry) were prepared. ...
Humic acids are the most active components of soil organic matter and have been shown to have an hormone-like activity thus stimulating plant growth. The objective of this work was to verify the quantitative and qualitative yield responses of the table grape cv. Italia after the application of a humic acid at various phenological stages. The humic acid used in this study has been extracted from...
Climate change is expected to increase temperature and decrease summer precipitation in Central Europe. Little is known about how warming and drought will affect phenological patterns of oaks, which are considered to possess excellent adaptability to these climatic changes. Here, we investigated bud burst and intra-annual shoot growth of Quercus robur, Q. petraea and Q. pubescens grown on two d...
Range species forages have different quality and feeding value in different site and times. Therefore research carried out to Investigate of Plantago Coronopus Forage Quality at different phenological Growth Stages in Five Habitats of Golestan Province (Goomishan, soofikam, Sangar Tappeh, Inchehbroon and chaparghoymeh). Samples were collected from two phonological stages (vegetative and seed r...
The crop coefficient (Kc) is widely used for operational estimation of actual evapotranspiration (ETa) and crop water requirements. The standard method for obtaining Kc is via a lookup table from FAO-56 (Food and Agriculture Organization of the United Nations Irrigation and Drainage Paper No. 56), which broadly treats Kc as a function of four crop-growing stages. However, the distinctive physio...
Information on forage quality could help rangeland managers to select suitable grazing method to achieve higher animal performance without damage to vegetation. The aim of this study was to determine and compare the forage quality of S. yazdiana and S. tomentosa, which are the most important species of saline rangelands in Ardakan in Yazd province, Iran. These two species are grazed by goats an...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
Improved understanding of the links between aboveground production and allocation of photosynthate to belowground processes and the temporal variation in those links is needed to interpret observations of belowground carbon cycling processes. Here, we show that combining a trenching manipulation with high-frequency soil respiration measurements in a temperate hardwood forest permitted identific...
