Effect of NAA and IAA on Stem Cuttings of Dalbergia Sissoo (Roxb)

Abstract

The plant cuttings is one of the most common methods of vegetative reproduction which is, today, used extensively due to low cost. In order to study the effect of various concentrations of Naphthalene acetic acid (NAA) and Indole acetic acid (IAA) on the rooting of semihardwood cuttings of Dalbergia sissoo , an experiment was carried out in a private field in Koya city in 2014. In this research, the treatments were prepared to include hormone of Naphthalene acetic acid in four levels of: (0, 100, 300 and 500 ppm) and Indole acetic acid in four levels of: (0, 100, 300 and 500 ppm), and the bottom part of the cutting was dipped into above solutions for 30 seconds. The results showed that the maximum percentage of the shooted cuttings, shoot length, number of main branch, diameter of main branch, leaf area, number & length of root, dry weight & biomass &dry matter of shoot, fresh &dry weight of root, biomass &dry matter of root and chlorophyll a belonged to IAA treatment with concentration of 500 ppm, NAA treatment with concentration of 500 ppm. Nitrogen and protein increased with concentration 300 ppm for IAA amd NAA auxins. The highest length of root belonged to IAA treatment with concentration of 500 ppm. All growth parameters were increased up to the highest concentrations of IAA 500 ppm. IAA was the most effective in promoting growth of Dalbergia sissoo cuttings.

Influence of indole butyric acid (IBA) concentrations on air layerage in guava (Psidium guajava L.) cv. Sufeda

“…Similarly,[28] reported that total leaf chlorophyll content in stem cuttings of three apple cultivars (Starkrimson Delicious, Golden Delicious and Misket Delicious) were significantly increased by treatment of 2000 and 3000 mg / IBA. On contrary,[29]…”

Development of efficient embryo-derived regeneration system and optimization of genetic transformation in cumin (Cuminum cyminum L.)

“…Indirect shoot regeneration through the callus causes somaclonal variation which is not desirable for transgenic plant development (Omar and Ahmed 2015).…”

“…It causes prominent shoot regeneration as the endogenous level of cytokinin eradicates external supplementation. Apart from these, NAA is also increasing the internal concentration of indole-3-acetic acid (IAA) which plays an important role in shoot regeneration (Omar and Ahmed 2015). Thus, NAA-supplemented media showed prominent regeneration e ciency.…”

Effect of NAA and IAA on the Rooting of Chrysanthemum morifolium Propagated by Tip Cuttings

“…Exogenous application of both rooting hormones NAA and IAA had a noticeable effect on the root and shoot parameters of Dalbergia sissoo (Omar and Khudhur, 2015). IAA is more effective than NAA on root development and growth (Ahmad, 2011).…”
