to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...
risk analysis is an important technique to estimate impacts on the environment for adopting effective measures to avoid risks. this field study was conducted to investigate the risk of brick kiln (bk) smoke on the shoots of acacia arabica. different phenotypic parameters including morphology and growth of shoots and epidermal imprints of the leaves were studied in the vicinity of a brick kiln s...
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...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
In order to improve the quantitative and qualitative traits of lisianthus (Eustoma grandiflorum “Mariachi Blue”) a factorial experiment ws performed as completely randomized design at three levels of vermicompost (0, 5 and 10% v/v) and humic acid (0, 2 and 4 kg/m3) with three replications, under the greenhouse conditions. Evaluated traits were number of Leaves, buds and branches, pe...
one of the main problems in the mass production of pepper transplant is the stickiness of seed coat to the cotyledony leaves that can lead to no emergence or having poor emergence of pepper seedlings. therefore, in order to evaluate the effects of different sowing depths and soil compactions on emergence and early seedlings growth of pepper, a greenhouse experiment was conducted in the faculty ...
In recent years, in the world and in Iran as well, attention to Lisianthus flowers has been such that its production has increased significantly. With the increase in the production of Lisianthus cut flowers, attention to nutrition and application of treatments to improve the growth and storability of this flower is felt more than ever. For this purpose, the effect of karrikin, salicylic acid a...

Background and Objectives: In arid and semi-arid regions, wastewater reuse has become an important element in agriculture. However, irrigation with this resource can be either beneficial or harmful, depending on the wastewater characteristics. The aim of this research was to investigate the soil bacterial and crops quality irrigated with treated wastewater. Material and Methods: This research ...
In 1998, H. Broersma and H. Tuinstra proved that: Given a connected graph G with n ≥ 3 vertices, if d(u) + d(v) ≥ n − k + 1 for all non-adjacent vertices u and v of G (k ≥ 1), then G has a spanning tree with at most k leaves. In this paper, we generalize this result by using implicit degree sum condition of t (2 ≤ t ≤ k) independent vertices and we prove what follows: Let G be a connected graph...
