in vitro propagation of rose has played a very important role in rapid multiplication of species with desirable traits and production of healthy and disease-free plants. micropropagation using nodal segments of rosa canina under different combinations of bap, ga3 and naa on ms and vs, medium was investigated. the results showed that the highest shoot proliferation was obtained on vs medium cont...

the sunn pest is a serious pest of cereals causing severe damage to cereals especially of wheat. its life cycle has two different phases, one is growth and development phase and the other is diapause phase which takes place in adult stage. in this study the effects of juvenile hormone analogue pyriproxyfen, ecdysone analogue methoxyfenozide and mixture of pyriproxyfen and methoxyfenozide on dia...

Background & Aim: Clematis is an ornamental and medicinal plant that is primarily planted as an ornamental plant. Clematis orientalis is native to Asia and Central Europe, used as an antiseptic and refrigerant. The propagation of Clematis is very important. In this study, the effects of plant growth regulators on rooting and growth of the plants in vitro cult...

abstract several root measuring methods have been developed until now but there is no single method of root measurement applicable for all situations. this study was conducted to evaluate the effects of a single trinexapac-ethyl (te) and paclobutrazol application on kentucky bluegrass root growth under three irrigation treatments. evaluating of root length density (rld), root surface area (rs) ...

dog rose (rosa canina l.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as rosa hybrid and rosa floribunda. in vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and disease-free plants. micropropagation of rosa canina l. was revised, usin...

Two insect growth regulators, methoprene and a benzyl-1,3,benzodioxole (J-2931), had no detrimental effects on Dugesia tigrina under field conditions. Three other compounds, resmethrin, temephos, and cyromazine, had only minimal effects. Asexual multiplication among these planarian predators exceeded 68% when combined with Culex quinquefasciatus larvae and methoprene at different concentration ...

dog rose (rosa canina) has been using as a rootstock for ornamental roses also it is one of the medicinal plants. it can be propagated under in vitro conditions. after removing chilling requirement of buds, axillary wood buds of dog rose were cut in three nodal positions (lower, middle and terminal) on the stem and then explants after decontamination, cultured on murashige and skoog medium (ms ...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...
