This study was designed to examine the effects of promoting substances on bud retention, rooting and plantlets survival of rooted cuttings on selected tree species using growth promoting substances. Stem cuttings were treated with rooting-promoting substances, planted in plastic pots filled with top soil and arranged using a completely randomized design (CRD) in a screen house. Stem cuttings of...

To enhance the genetic resource base of Echinacea purpurea (L.) Moench, a tetraploid was developed by treating seeds with different concentrations of colchicine. For further multiplication, in vitro micropropagation through adventitious shoot induction and proliferation was achieved. Shoot buds were induced directly on adaxial surface of mature leaf tissues growing on MS medium supplemented wit...

A novel micropropagation method for pineapple (Ananas comosus L.), based on shoot elongation induced in vitro, was demonstrated for two cultivars. Decapitated in vitro plantlets were used as explants. Shoot etiolation was induced by placing explants in a Murashige and Skoog (MS) medium containing NAA (10 μM) and incubating in darkness at 28C for 30 to 40 days. The mean number of the regenerated...

To know what a physio-chemical situation in the micro-propagating banana variety Basrai under saline conditions, an experiment was conducted. In vitro plantlets were developed by culturing meristematic stem tips (explant) for 3 weeks on organogenesis (8.0 μM BA; 10.0 μM IAA; 3.0 g l phytagel), 3 weeks on shoot induction (15.0 μM BA; 1.0 g l phytagel) and 4 weeks on shoot multiplication (10.0 μM...

BACKGROUND Chlorophytum borivilianum is an industrially valued medicinal crop. Propagation through seeds is not feasible because of low germination percentage and long dormancy period. Therefore, callus culture and plant regeneration can be an alternative to improve this crop production. Also, callus can serve as an alternative source of bioactive compounds. OBJECTIVE To evaluate the effect o...

Somatic embryos and rooted plantlets have been regenerated from light-initiated embryogenic callus derived from mature embryos of Picea abies stored seeds. Under a 16 hour photoperiod, mature zygotic embryos were cultured on a modified half-strength Murashige-Skoog medium without NH4NO3 and supplemented with 5 mM glutamine, 4.5 pM N6-benzyladenine (BA) and 10.7 PM naphthalene-acetic acid (NAA) ...

This study describes the standardization of an efficient in vitro propagation and hardening procedure for obtaining plantlets from shoot tips of Hemp (Cannabis sativa L.). Hemp seedlings were germinated on half-strength 1/2 MS medium supplemented with 10 g·Lsucrose, 5.5 g·Lagar at a pH of 6.8 under light for 16 h per day. MS medium containing 0.2 mg·LTDZ, 0.1 mg·LNAA supported the maximal auxil...

In vitro propagation method was developed for obtaining large number of plantlets of Valeriana wallichii DC. (Valerianaceae), an indigenous high value medicinal and aromatic plant species of Indian Himalayan region, using nodes of in vitro grown seedlings. High frequency shoot proliferation was induced in explants cultured on Murashige and Skoog (MS) medium supplemented with different concentra...

PHL-C is one of the dwarf sweet cherry rootstocks which is a hybrid between P. avium L. × P. cerasus L. Direct rooting of sweet cherry rootstocks is difficult which can be solved by using in vitro propagation. Transfer of plantlets from in vitro to ex vitro limit the use of micro propagation, because of weak root systems and low survival rates. This study was conducted in order to select the be...

To investigate the suitable medium for in vitro shoot regeneration and plantlet growth of Dendrobium crumenatum Sw., individual protocorm-like bodies (PLBs) (about 4 - 5 mm diameter) Sw. derived from MS supplemented with 0.5 mg/L TDZ 60 days culture were cultured on 6 media; Murashige Skoog (MS) medium, 15 % (v/v) CW, CW 0.2 (w/v) AC, Vacin Went (VW) VW AC. After months culture, containing coco...
