Screening and peculiarity of the biological action of synthetic plant growth regulators
نویسنده
چکیده
As a result of biological screening among synthetic compounds that have growth regulatory activities in culture tissues in vitro and in vivo in plants, 5 perspective substances were chosen as the substitutes of phytohormones. Thus, it was found that Ivin (N-oxide 2,6-diniethylpyridine) revealed predominant cytokinin activity in vitro and a cytokinin-gibberelin activity in vivo; Methyur (Na-derivative 6methylthyouracyl) showed an expressive cytokinin-gibberellin activity in vivo; Triamelon (Iodide tris (2,2-trimethylammoniummethyl phosphate) revealed a cytokinin-auxin activity in vitro; preparation D-107 (I-acetylamino-1-acetylthyo-2-oxo-2-phenylethan) revealed an auxine-like effect and the preparation N 2622 (derivative tetrahydrothyophendioxide) showed an expressive auxin activity in vivo. The model of mediated action of plant growth regulators through phytohormones is proposed.

متن کاملImprovement of Rooting in Forsythia × intermedia Cuttings by Plant Growth Regulators
Asexual propagation through cuttings is an appropriate method used for most ornamental plants. Success in increasing the percentage of rooting, reducing root emergence and increasing proliferation efficiency depends on several factors like plant growth regulators, especially auxins. Rooting of Forsythia × intermedia is difficult and requires specific hormonal treatments and proper cultivation b...

Studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as Henna. The purpose of this study is to determine an appropriate concentration of Naphthalene Acetic Acid (NAA), Indole Butyric Acid (IBA) and salicylic acid (SA) on Rooting of Henna. Present study showed that there was a great variation in most of the measured characters at P<...

Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...
