Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).

Growth regulators especially auxins and cytokinins are critical for plant in-vitro regeneration. The effect of these plant growth regulators on in-vitro propagation of Saccharum officinarum L (Sugarcane) was investigated. In vitro response of two different varieties of sugarcane (NCS 005 and NCS 008) to Plant Growth Regulators was obtained in this study. Formation of buds was obtained on shoot apical meristem when cultured on MS (Murashige and Skoog) medium supplemented with 0.1mg/l BAP (6-Benzylaminopurine). After two weeks of initiation, regenerated meristem was inoculated into MS (Murashige and Skoog) fortified with different concentrations and combination of cytokinins. Shoot multiplication was optimal on 0.5mg/l BAP + 0.25 mg/l Kin(Kinetin) for NCS 005 variety while for NCS 008 variety, no significant (P≥0.05) difference was observed between 1.5mg/l BAP and 1.5mg/l BAP +0.5mg/l Kin. The best root induction for in vitro derived shoots was obtained on 1.0 mg/l NAA (Naphthalene acetic acid) and 2.0 mg/l IBA( Indole butyric acid) for both varieties of sugarcane within ten days of culture transfer. Successfully established plantlets showed excellent growth response when weaned under regulated green house conditions.

Caesalpinia Bonducella

Aim: Caesalpinia bonducella Flem is a dioecious scrambling woody liana of Caesalpinoideae, a subfamily of Leguminosae. The plant is threatened and distributed in the deciduous forests of the Western Ghats of India. Being an important medicinal plant Caesalpinia bonducella F. attracted many scientists to exploit various activities associated with a number of phytoconstituents. The present study was undertaken to evaluate the most suitable media and suitable concentrations of plant growth regulators for in vitro Callogenesis and screening of antimicrobial activity of callus and seed of Caesalpinia bonducella. Materials and Methods: Callus was initiated from stem explants, on 1x and 0.5x MS medium plus supplements. The effects of plant growth regulators on callus cultures were studied and observations were made. The in vitro antibacterial activity was performed by using extracts of callus and seed of Caesalpinia bonducella in petroleum ether and methanol against multidrug resistance organisms. The organic extracts of seed and callus of the plant at concentrations of 0.02 mg/ml - 0.1 mg/ml were taken and their activities were measured.   Results: The combination of 2.5 mgL-1 2,4-D  with 2 mgL-1 BAP, resulted in the highest frequency and the highest mean percentage of callus formation (2.35 ± 0.294) with yellow friable callus. The results revealed that all the extracts had a variable degree of antibacterial activity. Conclusions: It was observed that 2,4-D at 2.5 mgL-1 in combination with BAP,2.0 mgL-1 BAP resulted in early initiation, highest induction percentage, with frequency highest mean percentage of callus formation, Antimicrobial tests with methanol and diethyl ether extract of Caesalpinia bonducella seed powder against the clinical isolates showed the zone of inhibition for all the pathogens tested with concentration of methanolic extract of C. bonducella seed powder.

Shoot, root, and callus induction were examined in the North American lily Lilium michiganense in response to treatment with four auxin-type plant growth regulators (PGR). Seed from controlled crosses were aseptically excised from slightly immature capsules and cultured in vitro on Murashige and Skoog basal medium and vitamins with 30 g·L−1 sucrose, 7.0 g·L−1 agar, and a pH = 5.7. Seed were maintained at 20 °C with a 14-h photoperiod. After 5.0 to 5.5 months, leaves and roots were removed from seedlings, the bulbs transversely sectioned, then the bulb sections cultured cut-surface down on the identical medium supplemented with 0.0, 1.0, 2.0, 4.0, or 8.0 μm dicamba, picloram, K-NAA, or 2,4-D. Morphogenetic response was tabulated 4 months after treatment. Shoot formation was promoted by treatment with dicamba, picloram, and K-NAA in comparison with the control (2.5 shoots/explant). Shoot formation varied significantly in response to individual dicamba, picloram, and 2,4-D concentrations. A maximum of 7.9 shoots per explant was promoted by 4.0 μm K-NAA and 1.0 μm dicamba, respectively. Root and callus formation also varied significantly between PGR treatments. Root formation was inhibited by dicamba, picloram, and 2,4-D treatments in comparison with the control (100% rooting); callus formation was promoted by dicamba, picloram, and K-NAA treatments in comparison with the control (15% callusing).

Gerbera Jamesonii

Gerbera plant Gerbera jamesonii is classified according to the flower colors to four strains: white, yellow, pink and purple. Capitulum and scape explants were tested on MS medium in half or full salts strength, supplemented with different combinations of plant growth regulators cytokinins kintin (Kin) and benzel adinine (BA), auxin indolacitic acid (IAA). Results revealed that the capitulum showed better response to shoot formation 64.13% whereas the scape did not show response. Yellow flowers showed higher response in shoot formation 37.5% than other strains. growth regulators combination BA and IAA (3.0 + 0.1) mg/L respectively showed better response for shoot multiplication. Auxin IBA (0.5) mg/ L gave better rooting percentage 60% than other auxins IAA and NAA all concentrations. The acclimatization of the gerbera was 78.59%.

Bud Induction

An efficient in vitro method for multiple shoot bud induction and regeneration has been developed in Artemisia annua L. using leaf and stem explants in various concentrations and combinations of plant growth regulators to evaluate the frequency of regeneration. The sources of explants as well as plant growth regulators in the medium were found to influence the multiple shoot induction. The result shows that the stem segment cultured on Murashige and Skoog (MS) medium supplemented with 0.1 mg/l thidiazuron (TDZ) gave a perfect shoot formation (100%) and good shoot multiplication (57 shoots/explant) after 2 weeks of culture. Healthy regenerated shoots were elongated and rooted in MS medium without hormones. The artemisinin content in plants regenerated from stem explants using 0.1 mg/l TDZ was (3.36 ± 0.36) μg/mg dry weight and two-fold higher than that of in vitro grown plants of the same age [(1.73 ± 0.23) μg/mg DW]. This system exhibited a potential for a rapid propagation of shoots from the stem explant and makes it possible to develop a clonal propagation of A. annua.
