The use of salicylic acid as a resistance inducer agent in several plant species was well known. Salicylic has been believed to play an important role inducing drought resistance. and dryness onion (Allium cepa L.) never studied. present study aimed ascertain how limited water supply (SA) interact with L. ) yield component traits. A completely randomized design (CRD) two-factor treatment three ...

Twenty one genotypes of six – parent half diallel were analyzed for estimating gene effects of variance, combining ability and standard heterosis for forage yield and other traits in barley. The estimates of gene effects revealed the significant role of additive genetic component (D) for the inheritance of days to 50% heading, plant height and spikelets per ear. The non-additive component (H1) ...

Shot peening is a process in which a stream of shot is blasted against an engineering component to generate a high compressive residual stress regime at the surface of the component. This paper describes a 3D finite element dynamic analysis of single shot impacting on a metallic component. The model is first validated against a published numerical study. A parametric study is conducted to inves...

abstract in current study, an irrigation examination and acquisition of environmental water in kor-river fields, that is dominated from doroudzan dam to bakhtegan lake, was done by an integrated economy-environmental model. the model was considered by economic, hydrologic and agronomic components. in the economic component, an optimal harvesting of water was done using non-linear programming in...

2-Methylpyridinum p-toluenesulfonate ([2-MPy][p-TSA]) as a novel room temperature ionic liquidwas synthesized and evaluated as a recoverable catalyst for the one-pot synthesis ofhexahydroquinoline-3-carboxamide derivatives by four-component reaction of arylaldehydes,dimedone, acetoacetanilide and ammonium acetate in high to excellent yield in ethanol at 50 oC.The [2-MPy]...

abstract rosa damascena has attracted considerable attention in horticulture, biochemistry and in pharmacology because of the fragrance of the flowers and the high content of its bio-logically active substances. there is limited information available on factors controlling flower yield and its components. the present study reports an investigation on flower yield and the various factors affect...

A simple, mild and high efficient procedure for one pot three component synthesis of 2-amino 4-H chromene derivatives was studied. The reaction was performed in water using aryl aldehydes, malononitrile and resorcinol, phloroglucinol or naphthole in the presence of N-methyl D-glucamine (Meglumine) as a green high efficient catalyst. The reaction was studied in thermal, microwave (MW) and ultras...

let $pounds$ be the category of locally compact abelian groups and $a,cin pounds$. in this paper, we define component extensions of $a$ by $c$ and show that the set of all component extensions of $a$ by $c$ forms a subgroup of $ext(c,a)$ whenever $a$ is a connected group. we establish conditions under which the component extensions split and determine lca groups which are component projective. ...
