Flower development and senescence was studied in Narcissus tazetta ‘Kashmir Local’. Flower development was divided into six stages (I-VI), from the tight bud stage to the senescent stage. Flower fresh and dry weight increased as the flowers progressed from bud to bloom and then declined during senescence. Membrane permeability of tepal tissues increased as the flower progressed through various ...

ABSTRACT- Heat stress causes flower and fruit abscission in pepper. This study was conducted in the greenhouses of Isfahan University of Technology to evaluate the effect of foliar application of Benzyl adenine (BA) and potassium silicate (K2SiO3) under heat stress condition on bell pepper. Two factorial experiments based on completely randomized design with four concentrations of BA (0, 0.06, ...

in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

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...

A study was conducted to test the effect of 58.5 mM maltose, glucose, fructose, galactose and sucrose, and sucrose concentrations of 14.6, 29.2, 58.5 and 117.0 mM supplemented with 200 mg L-1 8-hydroxyquinoline sulphate (HQS) on the vase life and stem fresh weight changes in waxflower (Chamelaucium Desf.). The effect of the interaction between sucrose and HQS concentrations on the vase life of ...

in order to evaluate the effect of harvest time on fruit weight, oil content and fruit bearing in the next year in some cultivars of olive (conservalea, amygdalolia, karidolia, koroneiki, arbequina, zard and rouwghani), an experiment was performed as a split plot in time based on crd (completely randomized design) with three replications at olive research station (tarrom–zanjan) during 2013 and...

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)...

In this experimental, effect of some of antifrost on morphology, anatomy content of selective almond cultivars flower buds of 3 late, medium and early flowering cultivars of almond in Pheranshahr region using factorial design base on complete block randomize with 3 replications was investigated. This region is considerate as cold temperate. Experimental trees were planted with 6×6 m in 2000. In...
