In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...
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...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
in this study, the effect of application time (immediately and one week after harvest) of some chemicals (rindite, carbon disulphide, gibberellic acid and thiourea) on breaking of dormancy and sprouting of potato (solanum tuberosum l., cv., marfona) minitubers was investigated. for the carbon disulphide (25 ml m-3 for four days) and rindite (0.2 ml l-1 for two days) application, minitubers were...
let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
one of the major problems in reproduction of potato minitubers, is the low germination due to dormancy period that it’s led to low germination percentage, vigor and rot of tubers planted. therefore a factorial experiment based on the completely randomized design with three replications was carried out with a topic of the effects of application of rindite in various concentrations (0, 0.2, 0.4 a...
ABSTRACT Potato seed is one of the largest costs a crop. This mostly due to incidence and spread viruses that occurs when crop grown in open field. Thus, it necessary obtain virus-free potato plantlets through meristem isolation, with subsequent cultivation protected environment, where easier control virus-spreading insects. One way increase greenhouse viability by multiplicating using high tec...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
Potato (Solanum tuberosum L.) is one of the most important economical vegetable. Minitubers are small seed tubers without pathogens that are produced from invitro plantlets after translocation to greenhouse and create healthy and high quality seed tubers. Hydroponic systems increase the production of virus-free potato minitubers. This research was carried out to study the effect of different gr...
