A mathematical model of the processes involved in carbon metabolism is described that predicts the influence of temperature on the growth of plants. The model assumes that the rate of production of dry matter depends both on the temperature and the level of nonstructural carbohydrate. The level of nonstructural carbohydrate is determined by the rates of photosynthesis, growth, and maintenance r...

in order to investigate the presence of carnation etched ring virus (cerv), samples of carnation (dianthus caryophyllus), sweet william (dianthus barbatus) and weed plants showing symptoms from greenhouses of khorasan razavi and northern khorasan provinces were collected in autumn 2009. polyclonal antiserum was used in order to detection of cerv by double- antibody sandwich-enzyme linked immuno...

Carnation vein mottle virus (CarVMV) was isolated from glasshouse-grown Dianthus caryophyllus L. originating from Split. The same virus was obtained also from D. caryophyl­ lus, D. carthusianorum L. and D. barbatus L. which were grown in the open in Zagreb and the surroundings. The virus was identified on the basis of host plants, non-persi­ stent mode of transmission by M yzus persicae Sulz. a...

present experiment was carried out to check the effect of different concentrations of sucrose (2, 4, 6%), ga 3 (25, 50, 75 ppm) and combination of sucrose and cuso4 (2% + 200, 4% + 300, 6% + 400 ppm), sucrose and ga 3 (2% + 25 ppm), (4%+50 ppm), (6%+75 ppm) on keeping quality and vase life of carnation cv. ‘eskimo’. some postharvest characteristics such as vase life, total soluble solids (tss),...

to investigate the effect of cinnamon, turmeric and carnation powders on growth performance, carcass characteristics, morphological and ph changes of intestine and blood serum oxidation status in broilers, 450 unsexed ross 308 day-old broiler chicks were randomly allotted in a completely randomized design with six treatments, five replicates and 15 birds per each replicate, for 42 days. the bro...

In senescing carnation (Dianthus caryophyllus L.) flowers, ethylene is produced from the gynoecium, and acts as a diffusible signal received by petals to induce the expression of 1-aminocyclopropane-1-carboxylate (ACC) synthase (DC-ACS1) and ACC oxidase (DC-ACO1) genes in the petals. This results in autocatalytic ethylene production in the petals. We investigated ethylene production in cut flow...
