Analysis of performance and survival rate of different oak species in severe climate of Zagros forests especially under global warming can help with management, conservation and restoration of these species. So, seeds of three oak species of Zagros (Quercus branti, Q. infectoria and Q. libani) were collected from Baneh forests and sown in the common gardens of Yasuj. Then, their growth paramete...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
the leaf nitrogen content is generally accepted as an indicator of food quality and as a factor affecting host selection by phytophagous insects. the alate pea aphids (acyrthosiphon pisum harris, aphididae) were given a choice among non-nodulated pea plants (pisum sativum l.) supplied with one of four nitrate-n levels (0, 3, 15 and 30 mm). when whole plants were exposed to aphids for 7 days, th...
BACKGROUND AND AIMS It is well known that plant aerial development is affected by light intensity in terms of the date of flowering, the length of stems and petioles, and the final individual leaf area. The aim of the work presented here was to analyse how shade-induced changes in leaf development occur on a dynamic basis from the whole rosette level to that of the cells. METHODS Care was tak...
Lettuce is one of the major leafy vegetables that is consumed as fresh and salads crops. Although, today, the tendency is to grow lettuce as hydroponic crop, there is not an optimal nutrient solution and growers use different nutrient solutions for growing lettuce. Therefore, an experiment was conducted to find an optimal nutrient solution to grow lettuce. In this experiment, the effect of va...
In order to evaluate the effect of row and plant spacings on the yield and yield components of three cultivars of forge sorghum, a field experiment was conducted in Isfahan University of Technology, Lavark, during spring, 2001. Experimental design was a split-factorial with three replications. Main plots consisted of three row spacings (45, 60, 75 cm) and subplots were combinations of three cul...
an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...
The number of leaves and their distributions on plants are critical factors determining plant architecture in maize (Zea mays), and leaf number is frequently used as a measure of flowering time, a trait that is key to local environmental adaptation. Here, using a large set of 866 maize-teosinte BC2 S3 recombinant inbred lines genotyped by using 19,838 single nucleotide polymorphism markers, we ...
A pot experiment was designed to investigate the effects of full, above and below ground interactions of wheat with wild oat on leaf characteristics and root to shoot ratio. This experiment was conducted as a factorial based on randomized complete design with four replications. The treatments included four interference levels (above ground, below ground, above and below ground and check wheat a...
In order to study the effects of GA3 on growth and the biochemical compositions of jujube (Ziziphus spina-christi) leaf, this experiment was conducted in 2011-2012, in department of horticultural science of faculty of agriculture Hormozgan University, Bandar abbas and nursery of Major Natural Recourses Office of Hormozgan province, as a factorial basis on completely randomized design with three...
