Abstract:

The function of glutamate dehydrogenase was studied in cultured sweetpotato (Ipomoea batatas) nodal explants. The glutamate dehydrogenase was fractionated to charge isomers. Supplementation of the growth medium with either naphthaleneacetic acid or benzyladenine in the presence of 20 mM NH4NO3 induced normal growth (type 1 sweetpotato). The basic and acidic charge isomers of glutamate dehydrogenase were not suppressed. Combined supplementation with 70 mM NH4+ and either 1 mg ∙ L−1 benzyladenine or 0.1 mg ∙ L−1 naphthaleneacetic acid caused growth retardation (type 2 sweetpotato) and the suppre

ABSTRACT Improving the quality and rate of opening of cut flowers is important to meet consumer demand. Thus, it is important to develop methods to control the rate of flower opening and senescence in ornamental plants. In this study, we investigated the effects of 1-naphthaleneacetic acid (NAA) in flower opening in rose (Rosa sp.) cultivars Princess Meg, Red Star and Madrid. Cut roses were maintained under different concentrations of NAA.

Abstract:

Friable embryogenic callus of American ginseng (Panax quinquefolium L.) was induced from root pith on Murashige and Skoog medium supplemented with 2 mg 2,4-D and 1 mg KIN/liter. Optimal callus growth occurred on medium containing 1.5 mg dicamba/liter. Plants were regenerated on MS medium supplemented with various concentrations of plant growth regulators (PGRs); the best PGR combination was 0.5 mg IBA and 0.1 mg NAA/liter. Chemical names used: (2,4-dichlorophenoxy) acetic acid (2,4-D); 3,6-dichloro-o-anisenic acid (dicamba); 6-benzylaminopurine (BA); gibberellic acid (GA); indole-3-butyric aci

Abstract:

A successful protocol was established for micropropagation in two selected varieties of exotic ornamental plants,Calathea crotalifera. The effects of different sterilization techniques, explant type, and the combination and concentration of plant growth regulators on shoots induction were studied. The axillary shoot buds explants sprouted from rhizomes in soil free conditions showed high induction rate of shoots with lowest contamination percentage when treated with combination of 30% (v/v) NaOCl, 70% (v/v) ethanol, and 0.3% (w/v) HgCl2.

Abstract:

Drosera rotundifolia and Drosera capensis (Droseraceae) are carnivorous plants grown as ornamentals and sources for homeopathic medicine. The aim of this study was to optimize nutrient and growth regulator concentrations for the in vitro propagation of these species. Half strength MS medium (1/2MS) was supplemented with kinetin (0.5, 2, 5 mg/l) or 6-benzyladenine (3, 5 mg/l) and plantlets were transferred to 1/2MS with or without cytokinins. After 8 weeks rosette diameter, plant height, number of roots, root length were recorded and plants were cultured in full strength MS, 1/2MS or 1/2MS with

Concentrated [4.9 mM (1,000 ppm) and 24.6 mM (5,000 ppm)] IBA solutions in 50% isopropyl alcohol were stored in amber and clear glass bottles at 3 temperatures [22–25°, 6°, O°C (72–77°, 43°, 32°F)]. No significant change in biological activity of the solutions or breakdown of IBA was observed for solutions stored for 4 and 6 months. Solution color changed during storage. Color development was dependant on storage temperature, but not on exposure to light. Chemical names used: IAA = indole-3-acetic acid; IBA = indole-3-butyric acid; NAA = 1-naphthaleneacetic acid

Abstract:

ABSTRACT Transcription of the Azospirillum brasilense ipdC gene, encoding an indole-3-pyruvate decarboxylase involved in the biosynthesis of indole-3-acetic acid (IAA), is induced by IAA as determined by ipdC-gusA expression studies and Northern analysis. Besides IAA, exogenously added synthetic auxins such as 1-naphthaleneacetic acid, 2,4-dichlorophenoxypropionic acid, andp-chlorophenoxyacetic acid were also found to upregulateipdC expression. No upregulation was observed with tryptophan, acetic acid, or propionic acid or with the IAA conjugates IAA ethyl ester and IAA-l-phenylalanine, indica

Abstract Spray applications of NAA or NAA ethylester at 1000 ppm acid equivalent (A.E.) reduced axillary bud number by 30% and 21%, and weight by 73% and 52%, respectively, on pinched potted chrysanthemums, Chrysanthemum ×morifolium Ramat. ‘Mountain Snow’ and ‘Mountain Peak’. Diameter of floral sprays and vegetative heights also were reduced with increasing concentrations. Flower number was not affected by the treatments. NAA treatments caused leaf epinasty, but NAA ethylester treatments did not. Chemical names used: 1-naphthaleneacetic acid (NAA).

Abstract:

Abstract Flower abscission from the pedicel is a problem in postharvest handling of Geraldton wax (Chamelaucium uncinatum Schau., Myrtaceae). 1-Naphthaleneacetic acid (NAA) dips or sprays (1) and silver thiosulfate pulsing (STS) (2) have been recommended to prevent flower abscission in Geraldton wax. NAA (40 μg·liter-1) dips are commonly used in Western Australia. This work was undertaken to determine whether NAA or STS is the more effective treatment for preventing ethylene-induced flower abscission in Geraldton wax.

Abstract:

Abstract Morphogenically regenerable callus was induced from young leaf and meristem tissues of garlic (Allium sativum L. cv. Howaito-Roppen). Five auxins were compared for their ability to induce morphogenic callus. In order of decreasing effectiveness, 2,4-D (0.1–3.0 mg·liter−1), 2,4,5-T (0.3–10 mg·liter−1), dicamba (10–30 mg·liter−1), and picloram (10–30 mg·liter−1) were capable of morphogenic callus induction, while NAA did not induce morphogenic callus formation over a wide range of concentrations. The morphogenic callus was nodular and gave rise to plantlets following transfer to medium

Abstract:

Different growth regulators combinations were tested on the production of anther callus in tomato cultivar IPA 5. Calli were induced on media supplemented with 1.0mgL-1 gibberellic acid (GA3), 0.05mgL-1 alpha-naphthaleneacetic acid (NAA) plus 0.1mgL-1 6-benzylaminopurine (BAP), or with 1.0mgL-1 BAP plus 1.0mgL-1 NAA. The medium containing 1.0mgL-1 BAP and 1.0mgL-1 NAA produced the highest calli frequency, and promoted plant regeneration by indirect organogenesis, when calli were transferred to 0.01mgL-1 BAP and 0.001mgL-1 NAA. Plants regenerated presented tetraploid cells and rare diploid cell

The objectives of this study were to investigate whether elicitors induce the production of taxoids in Taxus globosa by testing the hypothesis that the cells induce a greater accumulation of taxoids depending on the type and concentration of the elicitor treatment tested. Cell cultures were initiated from Taxus globosa friable calli for producing taxoids using the Gamborg medium supplemented with different initial combinations of growth regulators as follows: naphthaleneacetic acid, benzylaminopurine, picloram, and polyvinylpyrrolidone.

Abstract Kiwifruit [Actinidia deliciosa (A Chev.) C.F. Liang et A.R. Ferguson, var. deliciosa] were propagated successfully by hardwood cuttings with bottom heat. Rooting improved in response to increasing bottom heat up to 24°C. Temperatures >24° damaged cuttings. Optimal results were obtained with bottom heat placed in a cold tunnel. In the heated greenhouse, rooting was unsatisfactory. NAA was the most effective auxin in promoting rooting, whereas IBA did not show appreciable effects. Chemical names used: 1-naphthaleneacetic acid (NAA); 1H-indole-3-butyric acid (IBA).
