Yield prediction before harvest is one of the important issues in terms managing agricultural policies and making right decisions for future. Using remote sensing techniques yield estimation studies steps many countries to reach their 21st-century targets. The aim this study develop a wheat model using Landsat-8 Sentinel-2 satellite data. In study, development stages winter were examined with h...

Background: The leaves, roots and seeds of Lovage (Levisticum officinale Koch) being used as an herb, vegetable and spice. Objective: The aim of this study is evaluation of the changes of phytochemical compound in aerial parts of the Lovage plants at different developmental stages as well as antioxidant activity. Methods: The plants were harvested from Hezar Mountain. After drying, essent...

Flowering time is strictly controlled by a combination of internal and external signals that match seed set with favorable environmental conditions. In the model plant species Arabidopsis thaliana (Brassicaceae), many of the genes underlying development and evolution of flowering have been discovered. However, much remains unknown about how conserved the flowering gene networks are in plants wi...

Chamomile (Matricaria chamomilla L.) is one of the most important medicinal plants in Iran. The main objective of this study was to determine the effects of organic nutrients on the yield and oil content of chamomile. The experiment was conducted in the spring of 2010. The treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the Aminol Forte sprays (no spraying or contro...

salvia genus belongs to lamiaceae family that was used in ancient and its application in culinary, flavor cosmetics, food and drinking industries is important. in the present study to assess compatibility of salvia sclarea to field condition and determine its potential for medicinal and ornamental applications, wild seed were cultured in pots. after initial growth, seedlings at 6-8 leaf stage t...

We investigated the effects of jasmonic acid (JA) and ethylenediamine-di-o-hydroxyphenyl-acetic acid (EDDHA) on floral induction and induction of turions in the photoperiodically neutral clone Djelekovec of the species Spirodela polyrhiza in axenical cultures. JA (0.475–47.5 nmol L–1) promoted floral induction under long-day (LD) and short-day (SD) conditions, while it had no effect on turion i...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...
