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...

This experiment was conducted to study the effect of cocopeat: perlite medium with three ratios (v/v) (1:1, 3:1 and 1:3) on some vegetative, flowering and biochemical parameters of two gladiolus cultivars (Strong and White) under soilless conditions in 2016. Data indicated that most vegetative parameters expressed as plant height, leaf number and leaf area, flowering parameter such as spike eme...

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...

A field experiment was conducted to determine the response of different doses of N and P2O5 on the growth and flower quality of gladiolus at farmer field district Quetta during the summer season 2008. Six treatments were included in the trial viz; T1 (125+100); T2 (125+200); T3 (150+100); T4 (150+200); T5 (175+100) and T6 (175+200) NP kg/ha were tested in four replicated randomized complete blo...

Wheat yield is largely determined during the period prior to flowering, when the final numbers of fertile florets and grains per spike are established. The aim of this study was to assess the dynamics of floret primordia development in winter wheat in response to pre-anthesis application of a synthetic cytokinin, 6-benzylaminopurine (6-BA). We conducted an experiment in which two foliar spray t...
