this experiment was conducted to quantify leaf production and senescence in wheat. the experiment was carried out at research farm of the gorgan university of agricultural sciences and natural resources, gorgan, iran in 2005 using a randomized complete design considering sowing dates as environment. treatments were sowing date (14 december, 20 jan and 21 feb, 2005) and cultivars (aria, atrak, k...

Indicators of nitrogen economy in winter wheat during vegetative development are a reliable tool for yield prognosis. This hypothesis was verified field experiment, carried out the 2013/2014, 2014/2015, and 2015/2016 seasons. The two-factor split-plot design, included following systems protection (CFP): (i) N + micronutrients, (ii) fungicides, (iii) micronutrients fungicides; rates: 0, 40, 80, ...

Two barley (Hordeum vulgare L.) forage varieties – Hemus and Karnobat, with high and low Rubisco content in the fully expanded first leaves (Metodiev and Demirevska-Kepova, 1992), were compared in pot vegetation experiments in respect of yield. Changes in the content of leaf pigments, the levels of total soluble and Rubisco immunoreactive protein were followed during six phenophases: 3rd leaf, ...

Calamus is a climbing palm marked by considerable internodal extension and limited stem-thickening growth, but with a surprisingly discontinuous axial vascular system. Stem bundles end blindly in a basipetal direction and are connected to each other only by narrow and late-developing transverse commissures. Vascular connection via leaf traces between stem and leaf is made over about nine plasto...

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...

There is little information about the effects of ethephon ripening hormone on the yield of sweet sorghum in Thailand. Therefore, this study aimed to evaluate the impact of ethephon hormone applied at different growth stages of three cultivars of sweet sorghum on its growth and yield. The experiment was conducted from December 2016 to May 2017 at a research plot of the Faculty of Agricultural Te...

The relationships between rooting potential with endogenous phenolic compounds, nitrogen and soluble carbohydrates of cuttings for five olive cultivars (‘Rowghani’, ‘Dusti’, ‘Tokhmekabki’, ‘Konservalia’ and ‘Amigdalolia’) were investigated. Extracts of the leaves and the base of the cuttings were used for analysis of biochemical compounds. Results showed that there were significant differences ...

to evaluate the effect of zn sulfate foliar application on morphologic and quantitative characteristics of safflower (carthamus tinctorius l.) cultivars, a field experiment carried out in ramin agriculture and natural resources university of khouzestan, iran, in a factorial arrangement in a randomized complete block design with four replications, during 2012-2013. treatments consisted of two sp...
