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.

Brassinosteroids (BRs) are new class of hormones noted to perform multiplephysiological functions in plant growth and development and have the potentialof influencing cell and tissue growth in vitro. Many naturally occurring BRs,including brassinolide, have been discovered, their mode of action and their growthpromoting activities on plants. The use of brassinolide in in vitro propagation isnew. The Murashige and Skoog (1962) medium was used as basal medium. Plantgrowth regulators - IAA, BA and BR - were added to the medium. The study usedthe Completely Randomized Design (CRD) in factorial with three replications.The cultivar of banana and plant growth substances affected the number of budsproduced, shoot length, root length, and stem girth. The interaction of thesetwo factors (cultivar x PGR) influenced the number of buds produced in vitroand the shoot length of the meriplants. The study shows that brassinolide has aninfluence on shoot induction, proliferation, and elongation of bananas in in vitro propagation.Keywords: Agriculture, in vitro propagation, induction, proliferation, elongation, apical meristem, plant growth regulators, cultivars, Isabela, Philippines

Artichoke (Cynara scolymus L.), a high economic value crop, was brought to Vietnam by the French in the late 19th century. The artichoke was mainly planted in Lam Dong, Lao Cai, Vinh Phuc provinces, etc. At present, the disease situation of Artichoke plants and the lack of disease-free seedlings result in insufficient source of Artichoke for producers. Artichoke plants are mainly vegetative propagation and pathogens easily transferred from mother to daughter plants. Therefore, low propagation rate and fungal infection are two main factors hindering the expansion and development of Artichoke cultivation (in Lam Dong). Therefore, studying and evaluating the situation of fungi and viruses as well as establishing the in vitro propagation procedures in order to produce high number of disease-free seedlings are urgent for the current Artichoke shortage. In this study, samples of purple and white Artichoke varieties, which suspected fungal manifestations, were collected to assessment of fungi and viruses in artichoke. In addition, in vitro propagation by cultivating apical meristem was applied to produce disease-free seedlings. The recorded results showed that, 19 strains of mold were identified on purple and white Artichoke belonged to nine genera including Mucor (M. sp., M. circinelloides, M. fragilis, M. irregularis, and M. racemosus), Alternaria (Alternaria sp., A. alterinata, A. gaisen, A. tenuissima, and A. tillandsiae), Fusarium (F. acuminatum and F. solani), Cylindrobasidium (Cylindrobasidium sp1 and Cylindrobasidium sp2), Actinomucor elegans, Curvalaria clavata, Plectosphaerella oligotrophica, Phoma herbarum, Rhizomucor variabillis; meanwhile, the Tomato mosaic virus (ToMV) was isolated only purple Artichoke. Shoot explants obtained from apical meristem culture were completely disease-free and used for micropropagation at the next stage.

Sprouted corm sections of “South Dade” white cocoyam were potted and maintained in a greenhouse for 8 weeks. Shoot tips of 3–5 mm comprising the apical meristem with 4–6 leaf primordial, and approximately 0.5 mm of corm tissue at the base. These explants were treated to be used into the culture medium. A modified Gamborg’s B5 mineral salts supplemented with 0.05 μM 1-naphthaleneacetic acid (NAA) were used throughout the study. Thidiazuron (TDZ) solution containing 0.01% dimethyl sulfoxide (DMSO) was used. Erlenmeyer flasks and test tubes were used for growing cultures. The effect of different media substrate, thidiazuron, and the interaction between TDZ and Benzylaminopurine (BAP) on cocoyam culture were tested. Results indicated that cocoyam can be successfully micropropagated in vitro through various procedures. All concentrations tested (5–20 μM BAP and 1–4 μM TDZ) produced more axillary shoots per shoot tip than the control without cytokinins. Greater proliferation rates were obtained through the use of 20 μM BAP and 2 μM TDZ, respectively, 12 weeks from initiation. Shoots produced with BAP were larger and more normal in appearance than those produced with TDZ, which were small, compressed, and stunted. The use of stationary liquid media is recommended for economic reasons.

A rapid micro propagation and acclimatization response of two different varieties of sugarcane Co86032 and CoN 04131(Saccharum officinarum L.) was obtained in this study. The shoot apical meristem of different sizes wascultured on Murashige and Skoog medium supplemented with different concentrations and combinations of ben-zylaminopurine and kinetin either alone or in combination with each other alongwith GA3. Best shoot formation response in Co 86032 was obtained on MS medium containing 1.5mg/l BAP while in CoN 04131 the combination of 0.5 mg/l BAP with 0.25 mg/l Kinetin showed best shoot formation response from apical meristem. Meristem of 3.0 mm size proved to be the best size for micropropagation of sugarcane. Excellent multiplication response of In vitro formed shoots was obtained when the concentration of BAP was decreased to 1.0 mg/l in Co 86032and 0.25 mg/l BAP and Kin in CoN 04131 (i.e. 0.25 mg/lBAP + 0.25 mg/l Kinetin. MS medium containing 1.0 mg/l NAA and 2.0 mg/l IBA showed 100% rooting response of In vitro regenerated shoots of both the varieties of sugarcane within eight days of inoculation. Best hardening response was obtained in sand+ soil + pressmud (1:1:1) media.
