Plantlet regeneration has been induced from callus tissue cultures obtained from petal parts of Hemerocallis cv. Chipper Cherry. Callus cultures capable of regenerating whole plantlets were established on the agar-solidified Murashige and Skoog's medium supplemented with (2,4-dichlorophenoxy)acetic acid (2,4-D) (1.0 mg/litre) + kinetin (1.0 mg/litre). The callus formed was dense, yellowish-green in color, and had what appeared to be meristematic protuberances. Shoots and roots developed when the callus was subcultured on a medium lacking 2,4-D.

Leaf explants of seven cultivars of Hawaiian anthuriums (Anthurium andraeanum Linden ex André cv. Kaumana, Kozohara, Marian Seefurth, Mauna Kea, Nitta, Ozaki, and Paradise Pink) produced callus most successfully after 2 to 3 months on a modified Pierik medium containing 0.36 μm 2,4-D and 4.4 μm BA. Petiole explants callused best on Pierik modified Pierik, and Finnie and van Staden media. Long-term cultures of callus from Univ. of Hawaii anthurium selections UH965, UH1060, and UH1003 were maintained for 12 to 13 months and were still capable of plantlet regeneration. Adventitious plantlets were recovered from callus plated on a Kunisaki medium containing 2.2 or 22 μm BA. Regeneration appeared to be organogenic rather than embryogenic and varied among the genotypes tested. Chemical names used: N- (phenylmethyl)-1H-purin-6-amine (BA); (2,4-dichlorophenoxy) acetic acid (2,4-D).

The influence of growth regulators, explants and their interactions on in vitro shoot bud formation from callus was studied in <I>Dianthus caryophyllus</I> L. The leaf and internode explants were cultured on Murashige and Skoog (MS) medium containing different concentrations of growth regulators. The highest callus induction was observed with 2 mg/l 2,4-dichlorophenoxy acetic acid (2,4-D) and 1 mg/l benzyl adenine (BA). Out of twenty seven shoot regeneration media tested, only 2 mg/l thidiazuron (TDZ) and zeatin alone or in combination with naphthalene acetic acid (NAA) and/or indole acetic acid (IAA) could differentiate calli. The highest average number of shoots was observed with 2 mg/l TDZ and 1 mg/l IAA. Significant differences were observed in calli producing shoots and number of shoots per callus in the explants of leaf and internode. The shoots were elongated and multiplied on MS medium supplemented with 1 mg/l BA and solidified with 1% agar. The shoots were rooted and hardened with 76% survival success in pots after six weeks of transfer to the pots.

Eleven different plant cell tissue cultures of both legume and non-legume origin have been grown in direct association, and in separate but close proximal association with both Spirillum lipoferum and Rhizobium sp. 32H1. Basic similarities were found in the nutritional requirement for the induction of nitrogenase activity (C2H2) in both organisms. In the absence of plant cell cultures both organisms need to be provided with a pentose sugar and a tricarboxylic acid to induce high levels of nitrogen-fixing activity. Plant cell callus tissue appears only capable of supplying the tricarboxylic acids needed but not the sugar component. The plant tissue, however, seems able to activate certain carbohydrates, which in themselves are incapable of substituting for the pentose additive.

Seedling-derived cotyledonary nodes and hypocotyl explants of BARI Dherosh- 1 were cultured in vitro on MS medium supplemented with varying concentrations of 2, 4-Dichlorophenoxy acetic acid (2, 4-D), 6- Benzylaminopurine (BAP), Thidiazuron (TDZ), BAP with 1-Nepthaleneacetic acid (NAA), BAP with Indole 3-butyric acid (IAA) and Zeatin with IAA along with a control. Shooting response (100%) with callus was only observed from cotyledonary nodes on thidiazuron (TDZ) where hypocotyls produced only callus or callus with roots on different concentrations of plant growth regulators. Considering the shooting response, the cotyledonary nodes of BARI Dherosh-1 were cultured on various concentrations of TDZ for regeneration. The highest percentage (64.0) with maximum number (6.8) of shoots per explant were observed in 0.044 ?M TDZ in 8.4 days. The regenerated shoots were rooted on ½ strength MS, MS supplemented with 2.46 ?M IBA and 0.53 ?M NAA. The highest percentage (83.3) and minimum days (9.7) required for root induction were recorded in 2.46 ?M IBA. The rooted plantlets were transferred to soil and hardened in the plastic pots under green house conditions. The rooted shoots grew normally under natural conditions following acclimatization.Bangladesh J. Agril. Res. 41(3): 521-528, September 2016

Sterilization procedure, media composition, explants selection and control of physical environment are critical for successful cultures and callus induction with surface sterilization being very challenging in most plants. Five different sterilization methods were evaluated to come up with the best for subsequent use to establish an in vitro regeneration method for the induction of callus in Curcuma caesia using excised leaf and rhizome explants. Murashige and Skoog (MS) media supplemented with various concentration of 2,4-Dichlorophenoxy acetic acid (2,4-D)/Indole-3-acetic acid (IAA) (0.5- 5.0mg/L), singly or in combination with Benzyl aminopurine (BAP)/Kinetin (KIN) (0.1-5.0mg/L), 0.3% sucrose and 0.08% agar were used. The result of the sterilization procedures showed 15% NaHClO3 (5min) + 70% Ethanol (30s) + 0.1% HgCl2 (5min) to be the most effective in controlling contamination in C. caesia among all the treatments tested. The response to callus induction was found to depend on the type of explants used and growth regulators combination. Leaf explants gave the highest percentage of callus induction. Highest percentage of callus induction (66.70%) was obtained in the growth regulator combination of 2, 4-D (0.5mg/L) + BAP (0.1mg/L) and least (14.29%) in IAA (2.0mg/L) + BAP (0.5mg/L). Equal and higher concentration of 2, 4-D + BAP of 5.0mg/L each also provided better result (40.00%). No callus was obtained in all the single concentration of 2, 4-D used.

Callus initiation and growth and plantlet regeneration were studied using eight cultivars of Raphanus sativus L., including six Japanese radishes, one Chinese and one small `Comet' radish. The basal medium was composed of Murashige and Skoog inorganic salts, 2.0 mg myo-inositol/liter, 0.5 mg each of nicotinic acid and pyridoxine·HCl/liter, and 0.1 mg thiamine·HCl/liter, 30 g sucrose and 2 g Gelrite/liter. High callus yields were obtained on basal medium containing (mg·liter-1) 0.1 2,4-D and 1.0 BA for two Japanese radishes and 0.1 NAA and 1.0 kinetin for `Comet' radish. Shoots were regenerated from callus by subculturing on basal medium containing 0.1 or 1.0 mg BA/liter and then transferring to basal medium. Rooting occurred on basal medium. Although callus was obtained in all eight cultivars, shoots and plantlets were regenerated only from `Moriguchi', `Nerima Shirinaga', and `Comet'. Chemical names used: 2-(l-naphthyl) acetic acid (NAA); N-(phenylmethyl)-lH-purine-6-amine (BA); 2,4-dichlorophenoxy acetic acid (2,4-D); 6-(furfurylamino)purine (kinetin).

A micropropagation system to obtain plants from inflorescences of pampas grass (Cortaderia selloana Schult. `Pumila') was developed. Factors examined included developmental stage of inflorescence cultured and growth regulator combinations and concentrations that support explant establishment, shoot regeneration, and rooting. Immature inflorescences ≈300 mm long formed many shoot primordia when initially cultured on Murashige and Skoog basal medium containing 4.5 μm 2,4-D and 8.9 μm BA and subcultured to medium with 0.4 μm 2,4-D and 4.4 μm BA. Thereafter, monthly transfer to a medium without growth regulators yielded about three shoots per tube per month for more than 6 months. Most shoots rooted spontaneously and were easily hardened to greenhouse conditions. Field-tested plants flowered within 2 years and nearly all appeared identical to the parent cultivar. With this technique, several thousand plants can be obtained from a single inflorescence in 1 year. Chemical names used: N -(phenylmethyl)-1 H -purine-6-amine (BA); (2,4-dichlorophenoxy)acetic acid (2,4-D).

An efficient protocol for callus induction of Withania somnifera through in vitro culture of shoot apex and leaf explant was standardized. Of the various combinations of phytohormones evaluated, MS media supplemented with 6-furfuryl aminopurine (KIN) 0.5 mg/l + 2,4-dichlorophenoxy acetic acid (2, 4-D) 2.0 mg/l was found to be bestfor mean callus induction (86%) in leaf explants after 6 weeks of culture and in case of shoot apex expant the best response and growth of callusing was observed on MS medium supplemented with 2,4-D 1.0 mg/l + BAP 2.0 mg/l (77%).The response of callus growth increases gradually with the reductions in concentration of KIN in culturemedium of both the explants. This protocol might be used in further research for mass propagation of W. somnifera via indirect regeneration methods.

Cocoa (Theobroma cacao L.) development using modern breeding techniques can be facilitated by propagation of planting material through somatic embryogenesis. Various factors that may affect embryogenesis are the composition of culture medium and culture condition. Hormone commonly used to initiate the formation of callus is auxin with type 2.4-D (2.4 Dichlorophenoxy acetic acid). The aim of this study was to determine the effect of the addition of 2.4 -D hormoneson the process of cocoa embryogenesis. The treatments were arragged in factorial combination in completely randomized design, which consisted of two factors. Thefirst factor was the concentration of auxin 2,4-D 25 %, 50 %, 75 %, and 100 %; and the second factor was cocoa clones; Sulawesi 01 and Sulawesi 02. The resultshowed that the addition of 2.4-D hormone up to 100% on somatic embryogenesis of cocoa for Sulawesi 01 clone was not significantly different from Sulawesi 02 clone for all parameters. While on the addition of 2.4-D, there was significant difference between Sulawesi 01 and 02. Cocoa embryogenic callus using the addition of 2.4-D (25%-100%) was significantly different from control. Increased concentrations of 2,4-D hormone which is applied onto media would inhibit the formation of the somatic embryo. Addition of 2.4 D 25%, encouraged towards non-embryogenic callus. Keywords: 2.4 Dichlorophenoxy acetic acid, embryogenic callus, somatic embryos, cocoa, medium culture, hormone
