Theory for the evolution of modifiers of the rate of mutation suggests that a lower rate of mutation may evolve after the breakdown of mechanisms that enforce outcrossing. Mutation accumulation (MA) experiments were conducted to compare deleterious mutation parameters in two closely related species of the plant genus Amsinckia, a group that exhibits wide variation in the mating system. One of t...

Both ploidy and hybridity affect cell size and growth vigor in plants and animals, but the relative effects of genome dosage and hybridization on biomass, fitness, and gene expression changes have not been systematically examined. Here we performed the first comparative analysis of seed, cell, and flower sizes, starch and chlorophyll content, biomass, and gene expression changes in diploid, tri...

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...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

to study the effect of foliar application of humic acid on morpho-physiological traits, nutrients uptake and postharvest vase life of cut marigold, an experiment was conducted with five levels of humic acid (0, 250, 500, 750 and 1000 ppm) based on completely randomized design with three replications. based on the results, in compared with control, leaf number and leaf area, total phenol and aer...

Objective: The inoculation of substrates with arbuscular mycorrhizal fungi (AMF) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. Methods: This experiment was conducted to evaluate the effects of AMF inoculation (0, 2.5, and 5 W/W) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...

This investigation was undertaken to study the effect of boron on flower and fruit setting and yield of ratoon crop of brinjal (Solanum melongina L) in the Eastern Region of Sri Lanka. The treatments were arranged in a Randomized Complete Design (RCBD) replicated three times. The treatments were defined as follows: T1-50 ppm, T2-100 ppm; T3-150 ppm and T4Control along with recommended fertilize...

BACKGROUND The flower buds of Syzygium aromaticum (clove) have been used in indigenous medicines for the treatment of male sexual disorders in Indian subcontinent. OBJECTIVE To evaluate the effect of Syzygium aromaticum flower bud on male reproduction, using Parkes (P) strain mice as animal model. MATERIALS AND METHODS Mice were orally administered lipid soluble components of Syzygium aroma...

respiration is one of the important factors to be considered in a determination of the quality of cut flowers during their postharvest preservation period. modified atmospheric packaging (map) is an effective way of reducing respiration rate along with increasing vase life while the quality of cut flowers also well maintained. this research was conducted on the basis of a factorial experiment, ...

The effects of concentrations of various biocides, in a solution containing 0.2 g l citric acid and 10 g l glucose, were tested on cut roses (Rosa hybrida L., ‘Classy’), Alstroemeria pelegrina L. and carnations (Dianthus caryophyllus L.). Compounds were evaluated for their effects on flower life (time to decline in fresh weight), maximum gain in fresh weight, solution uptake from 4 to 6 days, r...
