Jasminum parkeri Dunn is a narrowly endemic, critically endangered woody ornamental shrub confined to sub-temperate zone of Western Himalayas, and rediscovered from its type locality after lapse about 100 years. In the present study, propagation technique J. parkeri, using stem cuttings, was established for first time through application auxins, namely, indole-3-acetic acid (IAA), 1-naphthalene...

In this study, we investigated the effect of plant growth regulators (PGRs) – auxins, gibberellin, cytokinin, abscisic acid, brassinosteroid, ethylene and their interaction with methyl jasmonate (JA-Me) applied to roots of the whole plants Kalanchoe blossfeldiana on the accumulation of anthocyanins in roots. The highest stimulation of anthocyanins synthesis was stated with application of JA-Me ...

Auxinic-like compounds have been widely used as weed control agents. Over the years, the modes of action of auxinic herbicides have been elucidated, but most studies thus far have focused on their effects on later stages of plant growth. Here, we show that some select auxins and auxiniclike herbicides trigger a rapid elevation in root cytosolic calcium levels within seconds of application. Arab...

Substantial evidence indicates that amino acid conjugates of indole-3-acetic acid (IAA) function in auxin homeostasis, yet the plant enzymes involved in their biosynthesis have not been identified. We tested whether several Arabidopsis thaliana enzymes that are related to the auxin-induced soybean (Glycine max) GH3 gene product synthesize IAA-amino acid conjugates. In vitro reactions with six r...

This study establishes a protocol for the induction of somatic embryogenesis in Anthurium andraeanum cv. Eidibel. The experiment was arranged in a completely randomized 5 x 5 x 5 factorial design using five explant types (whole leaves, half leaves; petiole; nodal segments and root segments) from in vitro plantlets; five auxins: indole-3-acetic acid (IAA), α-naphthaleneacetic acid (NAA), indole-...

In field trails on lemongrass (Cymbopogon citrates), the effect of growth regulators, viz. indole butyric acid (IBA) and mepiquat chloride (MC), and their mode of application was studied to assess their effects on growth, oil yield and hormonal contents. The results suggested that application of growth regulators had no favourable effect on growth and oil yields in lemon grass. However, applica...

Sericostoma pauciflorum Stocks ex Wight(Family Boraginaceae) used against cancer, diabetes and known to be health promoter. Callus cultures have been established from the stem explants on Murashige and Skoog (MS) medium supplemented with 1.5 mg/L concentration of different growth hormone viz. kinetin (Kn), indole 3-acetic acid (IAA) and indole 3-butyric acid (IBA). At 6 weeks of age, these call...

This study aimed to explore the effects of different concentrations indole-3-acetic acid (IAA), indole-3-butyric (IBA), and indene-naphthaleneacetic (ABT-1) on rooting dynamic changes endogenous hormone content Australian Mulberry (vegetable Mulberry) Kirin mulberry (Fruit hardwood cuttings. As exhibited by results, process both vegetable fruit could be divided into three stages, namely initiat...

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<...
