tuberose (polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. tests were done to examine the effects on of nano-silver (ns) (0, 15, 30 and 45 mg l-1) and sucrose (0, 4 and...

the present research was carried out to evaluate the response of seven selected persian leek accessions to in vitro gynogenesis. the experimental design was a factorial one based upon a completely randomized design of three culture media treatments b2d0 (2 mgl-1 ba), b2d2 (2 mgl-1 ba and 2 mgl-1 2, 4-d), and b2d4 (2 mgl-1 ba and 4 mgl-1 2, 4-d) along with seven persian leek accessions (gorgan, ...

Flower-like ZnO nanostructures were synthesized by a facile wet chemical method. Structural, optical and photocatalytic properties of these nanostructures have been studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and UV-vis absorption spectroscopy. SEM and TEM studies revealed flower-like structures consistin...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in tropical and subtropical areas. this flower has forth order in cut flower and second order in bulbous plants production in iran. plant spacing and nitrogen necessity are the most important factors for tuberose quality and quantity. in this study, field experiment carried out as factorial design in randomized complete ...

Rose (Rosa hybrida L.) plants grown for cut-flower production in greenhouses produce flowers in flushes year-round. Crop models for this system must handle the cyclical nature of productivity, which is determined by the horticultural production methods. Nutrition was not accounted for in previous rose growth models, since little is known about uptake of the essential nutrients by rose roots. Th...

Orchidaceae, one of the largest angiosperm families, has significant commercial value. Isolation of genes involved in orchid floral development and morphogenesis, scent production, and colouration will advance knowledge of orchid flower formation and facilitate breeding new varieties to increase the commercial value. With high-throughput virus-induced gene silencing (VIGS), this study identifie...

An AP1/AGL9 group of MADS box gene, OMADS1, with extensive homology to the Arabidopsis AGAMOUS-like 6 gene (AGL6) was characterized from orchid (Oncidium Gower Ramsey). OMADS1 mRNA was detected in apical meristem and in the lip and carpel of flower. Yeast two-hybrid analysis indicated that OMADS1 is able to strongly interact with OMADS3, a TM6-like protein that was involved in flower formation ...
