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...

An investigation was conducted to study the effect of plant growth regulators on rice (variety Sarju-52) grown under sodic conditions, during kharifseason 2018 at students’ instructional farm ANDUA&T, Kumarganj, Ayodhya. The experiment laid out in randomized block design with nine treatments and three replications, different concentrations modes application (PGRs). PGRs were applied as foll...

It is known that most chemicals, which have been increasingly used since ancient times, carcinogenic and mutagenic effects. As an alternative to these natural compounds, such as plant growth regulators (PGRs) used. However, are the PGRs obtain efficient plants in agriculture harmless it thought today when essential access foods food sectors? Therefore, this study investigates activity of two (K...

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 d...

Demands for plant growth regulators (PGRs; chemicals that control plant growth) are increasing globally, especially in developing countries. Both positive and negative PGRs are widely used to enhance crop production and to suppress unwanted shoot growth, respectively. Strigolactones (SLs) are multifunctional molecules that function as phytohormones, inhibiting shoot branching and also functioni...

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...

the aim of this review was to represent a category of applied plant biostimulants and to highlight the effect of their application on morphological and phytochemical properties of medicinal plants in in vivo and in vitro conditions and their mechanism of action. plant biostimulants, safe for both human beings and the environment, are substances or materials, except for nutrients and pesticides,...

abstract the goal of this experiment was to save apricot flowers from late spring frost damage. this experiment was conducted during 2007-2008 to examine the effect of application of different concentrations of gibberellic acid in two forms pure (ga3) and impure (berelex) at (0, 50, 100, 200, 300 mgl-1) at 23 august and 23 september to delay flowering in apricot asgarabad cultivar. a factorial ...

In vitro culture has the greatest commercial value in extremely quick creation of clonal plants compared to conventional techniques propagation. It also proven be tremendous practical utility as assistance development and maintenance disease-free planting material, germplasm conservation, supplements regular methods plant progress, such genetic engineering. The discovery implementation current ...
