Rhodothamnus sessilifolius is a species of the Ericaceae family endemic to Artvin province in NE Turkey. This critically endangered list and current populations are decreasing, therefore, it requires protection reproduction. Thus present study aimed investigate effect various gibberellic acid (GA3) applications on germination R. seeds. The effects GA3 concentrations final percentage, mean time,...

Prolonging the marketing period of peach fruits in Egypt through introducing new cultivars, breaking dormancy early or delaying maturity of some cultivars by safe compounds would increase the growers' profits. This study was conducted during two successive seasons 2005 and 2006 by using "Desert Red" peach cultivar (Prunus persica L.) grafted on Nemaguard rootstock. Trees were grown at El-Noubar...

A two-year (2020-21) study was conducted to investigate the possibility of relying ten-years old pear trees grown on sandy loam soil irrigated by drip citric acid (CA), gibberellic (GA3) and humic (HA). The CA applied at concentrations 500, 1000 1500 ppm, GA3 50, 100 150 ppm HA 3, 4 5%, whereas water spray used as control. results our proved that CA, improved shoot length, thickness, leaf area ...

To date, economically and energy-costly vegetative propagation using rhizomes tissue culture are the only options for cultivation of Miscanthus spp. Some genotypes miscanthus produce fertile seeds, offering a valid alternative to propagation. A preliminary study has been conducted on seeds two hybrids obtained via interspecific cross-pollination between M. sacchariflorus sinensis: ‘GRC14’ (mate...

Date palm plantlets derived from tissue culture suffer from slow rate of growth. Large sizes, of such plantlets, are also sold for higher price. Thus, producers and growers are demanding a method to stimulate the growth rate of these plantlets regenerated by tissue culture. In this study, gibberellic acid was applied alone at 100 ppm or informulations at 50 ppm. Phosphoric acid at 1%, v,v and u...

introduction   heavy metal contamination has disastrous effects on plant productivity and threatens human and animal health. among metals, cadmium (cd) is commonly released into the environment from industrial processes. cd is known to cause cellular damage in plants by producing oxidative stress via the over-production of reactive oxygen species (ros). to combat oxidative damage, plants have d...

This study was conducted during two successive seasons 2005 and 2006 by using "Desert Red" peach cultivar (Prunus persica L.) grafted on Nemaguard rootstock. Trees were sprayed with a hand sprayer to the run off at the initiation of phase ΙΙΙ of the double sigmoid curve before the onset of the climacteric. The treatments included putrescine at 5 and 10 mM, GA3 at 200 and 400 ppm, in addition to...
