abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

In this work, a composite of corn starch grafted (-g-) guar gum was synthesized by polymerization process using tamarind kernel powder as polysaccharide. Firstly, grafting done with and saponification alkali, i.e., sodium hydroxide (NaOH). It further derivatized through condensation thermally treated at different temperatures. This leads to some chemical structural changes in the compound. The ...

Iron is an essential nutrient for the growth of most bacteria. To obtain iron, bacteria have developed specific iron-transport systems located on the membrane surface to uptake iron and iron complexes such as ferrichrome. Interference with the iron-acquisition systems should be therefore an efficient strategy to suppress bacterial growth and infection. Based on the chemical similarity of iron a...

in this study, we aimed to determine the effects of halo-priming on yield and yield components of four wheat cultivars in a saline soil. a field study was conducted in factorial based on randomized complete block design (rcbd). soil ph was 8/1 and electrical conductivity was 9 ds/m. wheat cultivars (falat, ghods, chamran and shoori4) were primed with cacl2 solutions (control, 0, 50 and 100 mm)....

In this paper we consider a natural generalization of the well-known Max Leaf Spanning Tree problem. In the generalized Weighted Max Leaf problem we get as input an undirected connected graph G, a rational number k not smaller than 1 and a weight function w : V 7→ Q≥1 on the vertices, and are asked whether a spanning tree T forG exists such that the combined weight of the leaves of T is at leas...

Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...

A subset S ⊆ V (G) is an independent set of G if no two vertices of S are adjacent in G. A subset Q ⊆ V (G) is a 2-dominating set of G if each vertex from V (G)\Q has at least two neighbours in Q. We define new kind of kernels in graphs. Using existing concepts of an independent set and a 2-dominating set, we define in the natural way the concept of 2-dominating kernels in graphs. A subset J ⊂ ...
