Aeroponic culture is an alternative method for optimizing growth of different plants in controlled conditions. Aeroponic systems are an efficient tool for the root studies and improving medicinal root production. In order to study the feasibility of valerian (Valeriana officinalis L.) production in aeroponic systems and assessing the effects of different NAA concentrations (0, 0.1, 0.3, and 0.5...

The population of many splendid orchids is reducing from their natural habitats at an alarming rate and their conservation is becoming a matter of global concern. Asymbiotic seed germination has been applied for ex situ conservation of rare, endangered and threatened orchid taxa and could provide rapid means their multiplication. In the present study reported here, seeds of an epiphytic and rar...

An efficient in vitro regeneration protocol from seed culture has been established successfully for Dendrobium chrysotoxum, an epiphytic orchid having tremendous ornamental and medicinal values. Seed germination response was encouraging in Mitra (M) medium enriched with different combinations of auxins and cytokinins. Medium supplemented with 0.4% activated charcoal (AC), 2 mg/L 6-benzyl amino ...

Cecropia is a relatively well-known and well-studied genus in the Neotropics. Methods for the successful propagation of C. obtusifolia Bertoloni, 1840 from cuttings and air layering are described, and the results of an experiment to test the effect of two auxins, naphthalene acetic acid (NAA) and indole butyric acid (IBA), on adventitious root production in cuttings are presented. In general, C...

Celastrus paniculatus, belonging to the family Celastraceae, is an important medicinal plant of India. Owing to the ever-increasing demand from the pharmaceutical industry, the species is being overexploited, thereby threatening its stock in the wild. Poor seed viability coupled with low germination restricts its propagation through sexual means. Thus, alternative approaches such as in vitro te...

This study represents the first paper of the effects of growth regulators on the physiochemical and phytochemical properties of the wax apple fruit, a widely cultivated fruit tree in southeast Asia. Net photosynthesis, sucrose phosphate synthase (SPS) activity, peel color, fruit firmness, juice content, pH value, total soluble solids (TSSs), and the sugar acid ratio were all significantly incre...

The present study was conducted to investigate the effects of different concentrations and combinations of plant growth regulators (PGRs) on callus induction of Tecomella undulata (Sm) Seem. The leaf segments were used as explants and cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of auxins such as NAA, 2,4-D, IAA and cytokikinins like BAP and KIN alone a...

The comparative analysis of plant hormones was undertaken on a 1-naphthaleneacetic acid tolerant mutant and normal tobacco (Nicotiana tabacum cv Xanthi) plantlets. The mutant plantlet was scrubby and impaired in its root morphogenesis. Degeneration of the root meristem was studied on tissue sections; it appeared very fast (as early as the 3rd or 4th day after sowing), after which the root was f...

Department of Biotechnology, Gulbarga University, Gulbarga 585106, Karnataka, India. [email protected] and [email protected] ABSTRACT: In this experiment the seed oils of 30 Neem (Azadirachta indica. A. juss) biotypes were screened and evaluated for their physio-chemical parameters for oil content, biodiesel yield, density, viscosity, iodine value , free fatty acid, saponification ...

Pollen extracts of date palm were used in tissue culture medium for banana as growth substances in comparison with growth regulators. Pollen extracts contain auxin (IBA) and tryptophan (auxin precursor). Water pollen extract (WPE) contains higher concentration of indoles compared with ethanol pollen extract (EPE). Most of treated plants showed highly growth characteristics such as shoot number,...
