salvia genus belongs to lamiaceae family that was used in ancient and its application in culinary, flavor cosmetics, food and drinking industries is important. in the present study to assess compatibility of salvia sclarea to field condition and determine its potential for medicinal and ornamental applications, wild seed were cultured in pots. after initial growth, seedlings at 6-8 leaf stage t...

Duration of various stages of inflorescence differentiation and hormone levels in apical buds eventually decide the harvest time, flower uniformity and quality of ornamental plants. The progress in inflorescence differentiation process in the chrysanthemum cultivar ‘Jingyun’ can be divided into nine stages. Following short day induction, it took 4d to reach the growing point hypertrophy stage, ...

Polar transport of the plant hormone auxin controls many aspects of plant growth and development. A number of synthetic compounds have been shown to block the process of auxin transport by inhibition of the auxin efflux carrier complex. These synthetic auxin transport inhibitors may act by mimicking endogenous molecules. Flavonoids, a class of secondary plant metabolic compounds, have been sugg...

We studied the evolution of leaf size, sapling canopy allometry, and related traits in 17 Acer species growing in the understory of temperate deciduous forests, using parsimony methods, randomization tests, and independent contrasts calculated on a phylogeny inferred from nuclear ribosomal internal transcribed spacer (ITS) sequences. Bivariate correlations and multivariate analyses indicated tw...

Populations of the rare annual forb Amsinckia grandiflora may be declining because of competitive suppression by exotic annual grasses, and may perform better in a matrix of native perennial bunchgrasses. We conducted a field competition experiment in which Amsinckia seedlings were transplanted into forty 0.64-m 2 experimental plots of exotic annual grassland or restored perennial grassland. Th...

The water in semiarid regions contains salts excess. When good quality is not available it necessary to use strategies that can make feasible the of saline water. aim this study was evaluate effects application plant growth regulator on culture basil stressed with salt. experiment carried out a randomized block design by matrix “Central Box Compound”. Shoot height, stem diameter, leaf area, dry...

Flowering plants exhibit one of two types of inflorescence architecture: indeterminate, in which the inflorescence grows indefinitely, or determinate, in which a terminal flower is produced. The indeterminate condition is thought to have evolved from the determinate many times, independently. In two mutants in distantly related species, terminal flower 1 in Arabidopsis and centroradialis in Ant...

Tomato is an important crop and hence there is a great interest in understanding the genetic basis of its flowering. Several genes have been identified by mutations and we constructed a set of novel double mutants to understand how these genes interact to shape the inflorescence. It was previously suggested that the branching of the tomato inflorescence depends on the gradual transition from in...

volatile components of three parts of pimpinella tragium vill. (umbelliferae family) from iran were investigated qualitatively and quantitatively for the first time. essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of p. tragium individually. the plant materials were collected from polour (northeast of tehran province). the yields of the stems p...
