in this study, postharvest characteristics of eight cut rose cultivars (valentine, king pride, prima donna, black baccara, victory, papagayo, royal baccara and yellow island) were investigated in a growth room with temperature of 20 ºc, relative humidity of 50% and light intensity of 10 µmol m-2 s-1 in autumn 2008. among cultivars significant differences were found for all of the attributes eva...

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...

a field experiment was conducted under controlled conditions in completely randomized factorial design with three soil application doses of zn sulphate and drought stress with three replications in chalus, mazandaran province, iran on 1th march, 2015. the treatments were included three amounts of zinc sulphate (0, 30 and 60 kg.ha-1) and three amounts of stress (90, 70 and 50% of field capacity)...

Pistachio is one of the most important horticultural crops in Iran.  There is a unique role for amino acids in the plant response to stressful conditions, and special physiological role for Arginine (Arg) compared to other amino acids.  The effects of this compound were investigated on vegetative and reproductive characters of bearing pistachio trees of ‘Ahmad-Aghaei’. The experiments were done...

In this paper we will present two upper bounds for the length of a smallest “flower-shaped” geodesic net in terms of the volume and the diameter of a manifold. Minimal geodesic nets are critical points of the length functional on the space of graphs immersed into a Riemannian manifold. Let Mn be a closed Riemannian manifold of dimension n. We prove that there exists a minimal geodesic net that ...

The architecture of spray cut chrysanthemum is crucial for the quality and quantity flower production. However, mechanism underlying plant still needs to be clarified. In this study, we measured nine architecture-related traits 195 varieties during a two-year period. results showed that number upper primary branches, lateral buds branch length widely varied. Additionally, height had significant...

Annual Chrysanthemum (Chrysanthemum coronarium L.) is one of the most widely cultivated garden flowers and highly suitable for loose flower, pot culture bedding purposes. The objective this research was to evaluate effect different mycorrhizal strains vermicompost on growth flowering coronarium. treatments comprise 4 mycorrhiza (No application, Glomus mosseae, Acaulospora laevis, Gigaspora marg...

BACKGROUND AND AIMS Flower colour varies within and among populations of the Rocky Mountain columbine, Aquilegia coerulea, in conjunction with the abundance of its two major pollinators, hawkmoths and bumble-bees. This study seeks to understand whether the choice of flower colour by these major pollinators can help explain the variation in flower colour observed in A. coerulea populations. ME...
