Cotyledon Explant

The effect of external BAP on explants including leaflets, stems, cotyledons with and without embryo axis of lentil (Lens culinaris Medic.) were tested on the frequency of shoot induction. The effect of different levels and combinations of various cytokinins on multiple shoot induction and elongation of shoots were compared. The effect of explant age and pH of media were also tested on shoot induction from various explants. Finally, the effect of IBA, IAA, and NAA on root induction of elongated shoots were examined. Optimum conditions for root emergence and growth and the hardening of seedlings were determined. Cotyledon with small part of the embryo axis was the superior explant. Shoot induction from the explants was enhanced by inclusion of BAP in the seed germination medium. The highest shoot induction (up to 96%) was obtained on MS with 7.5 µM 2-ip, 4 µM kn, and 2 µM TDZ. Over 80% of the elongated shoots produced roots in solid 1/4 BS media with 50 µM NAA for 3 days followed by 10 days in a mixture of liquid 1/4 BS, vermiculite and sand. Root development and hardening of the seedlings was achieved by using a hydroponics system containing Arnon’s solution. Tissue culture derived plants were transplanted to the greenhouse where the seeds were harvested after about 4 months.   Key words: regeneration, Cotyledon, Embryo axis, Lentil, Lens culinaris   D.

Polygonum Hydropiper

An efficient protocol for plant regeneration through multiple shoots induction from shoot tips of Polygonum hydropiper (L.) was established. The highest percentage (96.6) of multiple shoot induction and number of shoots (9.0) per culture were found on MS supplemented with 2.0 mg/l Kn. The induced shoots were excised and inoculated on to MS contains different concentrations of IBA or NAA for rooting. The highest percentage (90.0) of root induction and the highest number of roots per shoot (12.0) was found on MS having 1.0 mg/l IBA. Well rooted plantlets were acclimated properly and transplanted in the soil under natural condition, where cent per cent plantlets survived and grew successfully. Key words:  Polygonum hydropiper, Shoot tips, In vitro propagation D.O.I. 10.3329/ptcb.v20i1.5970 Plant Tissue Cult. & Biotech. 20(1): 73-79, 2010 (June)

Shoot Number

A rapid, simple and efficient protocol for <i>in vitro</i> multiple shoot induction and plantlet regeneration was achieved from three different explants of <i>Cicer arietinum</i>. The explants viz shoot tip, cotyledonary node and node were cultured on MS medium fortified with Benzyl Adenine (BA) (0.44&minus;8.88&mu;M) for multiple shoot induction. Multiple shoots proliferation was best observed at 4.44&mu;M BA from all the three explants within two weeks of culture. Of the three different explants tested, cotyledonary nodes produced the maximum number of shoots. Shoot number per explant ranged between 7 and 15. Individual shoots were aseptically excised and subcultured in the same media for shoot elongation. The elongated shoots were transferred to Indole Butyric Acid (IBA) (2.46&minus;12.30&mu;M) for root induction. Rooting was observed within two weeks of culture. Rooted plantlets were successfully hardened under culture conditions and subsequently established in the field conditions. The recorded survival rate of the plants was 76.3%. Plants looked healthy with no visually detectable phenotypic variations.

Basal Media

Citrus is an important genius for economy and human health but a susceptible genius against biotic and abiotic stresses, so it needs to improved programs. Different basal media (MS, ½MA, ?MS and DKW) and different kind and concentrations of plant growth regulators i.e. BA, KIN, 2ip, ZE and TDZ (0 – 2 mg/l) and NAA, IAA and IBA (0 – 2 mg/l) added with 30 g/l sucrose, 3 g/l active charcoal and 7.5 g/l bacteriological agar] were used for organogenesis include shooting and rooting, also callusing from nodal explant of Citrus latifolia. MS medium supplemented with 1 mg/l BA, and 0.01 mg/l NAA is the best media for multiple shoot induction on nodal explants and elongation of them. Other cytokinins had not significant effects on shoot induction and multiplication. Using of 0.01 mg/l IBA instead of 0.01 mg/l NAA on medium with 1 mg/l BA, led to multiple shoot induction on nodal explant indirectly. Rooting was induced on DKW medium plus 1.5 mg/l NAA in the best way compared another media. Both direct and indirect organogenesis (multiple shoot induction) were carried out on media with very similar contents. So we can use very simple and practical methods tissue culture for different improved programs in Citrus genius genius.

Regeneration Efficiency

The shoot-tip explant harvested from ethyl methane sulphonate (EMS) and gamma ray (GR) mutagenized seedling was cultured over MS medium fortified with NAA and BAP for five generations to amplify the mutated sector. Mutagens reduced the regeneration efficiency of the explant and affected its plant growth regulator-dependence for multiple shoot induction. While the 12d-old shoot-tip from GR-treated seedling induced shoots with 0.5µM NAA+6.6µM BAP; that from EMS-treated seedling induced shoots with 8.8µM BAP. The present study establishes that the mutagens affect the regeneration process in the explant.
