A protocol for in vitro cloning of mature plants of Citrus limon using nodal shoot segments has been developed. Three to four shoots were induced per axillary meristems on MS medium amended with 9 μM BAP. Repeated transfer of the initial explants for up to six passages on MS medium [having 50% of the original concentrations of NH4NO3 and KNO3, and supplement of 250 mg L (NH4)2SO4] with 0.22 μM ...
An in vitro regeneration protocol was developed for Capsicum chinense Jacq. cv. Naga King Chili, a very pungent chili cultivar and an important horticultural crop of Nagaland (Northeast India). Maximum number of shoot (13 ± 0.70) was induced with bud-forming capacity (BFC) index of 10.8, by culturing nodal segments in Murashige and Skoog (MS) medium supplemented with 18.16 μM Thidiazuron (TDZ) ...
BACKGROUND The low survival rate of in vitro regenerated Panax ginseng plantlets after transfer to soil is the main obstacle for their successful micropropagation and molecular breeding. In most cases, young plantlets converted from somatic embryos are transferred to soil. METHODS In vitro thickened taproots, which were produced after prolonged culture of ginseng plantlets, were transferred t...
Stevia rebaudiana Bertoni that conventionally propagated by seed or by cuttings or clump division which has a limitation of quality and quantity seed material. In present study, callus culture technique was tried to achieve rapid plant multiplication for quality seed material. Callus induction and multiplication medium was standardized from nodal as well as leaf sagments. It is possible to main...
Rapid clonal propagation through in vitro techniques using cotyledonary node as an explant has been attempted in the high yielding, tikka-susceptible (ICG 11337, AK 1224, ICGS 44, JL 24) and tikka-immune (ICG 6284) varieties of Arachis hypogaea L. Cotyledonary nodes were excised from the 12–15 days-old axenic seedlings and cultured in the presence of various concentrations of N6 –benzylaminopur...
the first successful and an efficient regeneration system on in vitro direct plant regeneration of agastache foeniculum was reported. the experiment were done in factorial design with three replications and explants were cultured in ms media fortified with different concentrations of bap and tdz (0, 2.2, 4.4, 8.8 μm) in combination with 3 levels of iaa (0, 1.1 and 2.2 μm). anova analysis showed...
From the rhizoplane of Oryza sativa, vars. Morelos A-88 and Apatzingan, rice plantlets, we isolated two bacterial strains: Corynebacterium flavescens and Bacillus pumilus. By scanning electron microscopy, endophytic bacteria were frequently identified at the base of secondary roots, between the epidermis and the mucilaginous layer. Endophytes were also identified in the intercellular spaces whe...
Kalanchoë daigremontiana reproduces asexually by generating numerous plantlets on its leaf margins. The formation of plantlets requires the somatic initiation of organogenic and embryogenic developmental programs in the leaves. However, unlike normal embryogenesis in seeds, leaf somatic embryogenesis bypasses seed dormancy to form viable plantlets. In Arabidopsis (Arabidopsis thaliana), seed do...
It is of interest to apply plant tissue culture to generate plants resistant to toxic effects of cadmium (Cd) on plant growth. Callus cultures were initiated from leaf explants of micropropagated potato plantlets (Solanum tuberosum L., cv. Iwa) for in vitro selection comprising 18 different Cd treatments varying in Cd exposure timing and duration. Plantlets regenerated from two different lines ...
The present study focuses on the development of a micropropagation protocol for true to type plants Anubias heterophylla, valuable ornamental aquatic plant. Natural propagation species is limited due production small number with long cultivation period, disease and requirement large space propagation. Surface-disinfected shoot tip explants were cultured MS medium containing 0.1 % (w/v) activate...
