Physalis Angulata

Physalis angulata L. is an important medicinal herb. An efficient direct adventitious plant regeneration protocol was developed for large scale propagation using leaf disc as explants. The explants were cultured on MS basal medium supplemented with 0.25-3.0 mg/L 6-benzyl amino purine (BAP) for primary shoot proliferation. Inclusion of indole-3-acetic acid (IAA) and gibberellic acid (GA3) in the culture medium along with BAP promoted a higher rate of shoot multiplication. The maximum number of shoots was produced in MS + BAP (1.0 mg/L) + IAA (0.5 mg/L) + GA3 (0.20 mg/L) after the third subculture. An average of 152.8 ± 0.40 shoots were produced from each leaf disc. For root induction the shootlets were transferred to MS medium supplemented with different concentrations of indole-3-butyric acid (IBA). The highest percentage of root induction was observed in 1.0 mg/L (IBA). Rooted plants were successfully established in the soil after hardening. The survival percentage of rooted plants on soil was found to be 85%. This result will facilitate the conservation and propagation of the important medicinal herb Physalis angulata L.

Micro Propagation

In the present investigation, experiment was conducted for in vitro micro-propagation with different concentration of growth regulators in different explants Sprouts and Shoot tips of potato cultivar Kufri Frysona. The maximum survival percentage (40) of sprouts and (100%) of shoot tips were obtained when the explants were surface sterilized with 0.2% bavistin & 0.4% streptocyclin (45minutes) and 0.1% mercuric chloride (60seconds). Sterilized explants were inoculated on MS basal supplemented with various growth regulators and established successfully. The maximum shoot induction (62.5±1.44%) in 11.3±0.33 days and (74.0 ± 2.13 %) in 10.0 ± 0.50 days were reported on medium PM1 (BAP 0.25 mg/l) in sprouts and shoot tip explants respectively. The sprouted explants were further sub-cultured on MS media supplemented with various growth regulator alone and in combination for in vitro multiplication. In Kufri Frysona (11.2) shoots were obtained on MS medium fortified with 0.25mg/l BAP + 0.01mg/l IAA on 42th day of subculture. In vitro rooting was observed on MS basal medium supplemented with 2.0 mg/l NAA in Kufri Frysona after 10 days. Rooted plantlets were successfully hardened in green house using different types of potting mixture and finally transferred to field. The protocol will be very useful for large-scale production of disease free planting material of potato (S. tuberosum) in future.

An efficient protocol was established for rapid and large scale propagation of woody aromatic medicinal plant Vitex negundo L. by in vitro shoot multiplication from shoot tips and nodal segments of mature plant. Of the four different growth regulators BA, Kn, GA3, NAA and coconut water, MS fortified with BA 1.0 mg/l was found to be the most effective for inducing multiple shoots from nodal explants. The percentage (96%) of shoot multiplication per node (21.83) was highest up to second subculture passages, after which there was a gradual decline in shoot development. Best rooting was induced (93%) in excised shoots on half strength MS medium supplemented with an optimal combination of NAA (0.3 mg/l). Soil, compost and sand (1:1:1) mixture was the most suitable planting substrate for hardening. The survival rate was 80% and the regenerated plants were successfully transferred to the soil.Key words: Vitex negundo, Medicinal plant, Shoot proliferation, Micropropagation, RegenerationDOI = 10.3329/bjsir.v43i3.1149Bangladesh J.

A micropropagation protocol via direct shoot organogenesis from Streptocarpus x hybridus Voss. leaf explants was established in this study. The shoot induction of three Streptocarpus cultivars (‘Snow White’, ‘Black Panther’ and ‘Slumber Song’) was successfully achieved on Murashige and Skoog (MS) medium supplemented with 0.2 mg L-1 -indole-3-acetic acid (IAA) and 0.2 mg L-1 thidiazuron (TDZ). In proliferation stage, the effects of two combinations of plant growth regulators -PGR- (V1-0.2 mg/L-1 IAA + 0.5 mg/L-1 BAP and V2-1.0 mg L-1 NAA + 0.2 mg L-1 TDZ) on shoot number and length were examined. The results suggest that PGRs combinations significantly influenced shoot proliferation and root induction in all Streptocarpus cultivars. Among the treatments, 0.2 mg L-1 (IAA) in combination with 0.5 mg L-1 6-benzylaminopurine (BAP) were the most effective for in vitro shoot multiplication and rooting. The in vitro rooting percentage was also determined before subjecting the plantlets to the acclimatization process. Due to acclimatization, Streptocarpus plantlets showed a very high rate of survival (90%). The generated PCR-RAPD profiles for the selected in vitro-raised plants and donor plants were similar which indicates the clonal or true-to-type nature of the progenies.

Abstract A micropropagation method was developed for a cold hardy purple raspberry cultivar (Rubus occidentalis × R. idaeus ‘Amethyst’). In vitro shoot cultures were initiated from shoot tips of a 30-year old ‘Amethyst’ plant. The effects of basal medium, plant growth regulator, and temperature on shoot proliferation were investigated. Shoots were produced from explants in both Murashige and Skoog (MS) and Driver-Kuniyuki Walnut (DKW) media supplemented with different concentrations of thidiazuron (TDZ) and benzyladenine (BA), solely or combined. One micro molar TDZ gave rise to the maximum proliferation rate. Interactions between BA and medium or TDZ were significant. Shoots produced on media with 1.0 μM TDZ had thick stems and small, dark green leaves whether BA was absent or present. Shoots can be rooted both in vitro and ex vitro with or without IBA at 0 to 1.0 μM. However, combination of rooting and shoot multiplication by adding a low level of TDZ to rooting medium produced multi-cane plants resulting in shortening propagation time, increasing survival rate, and lowering the production cost.

Several rose species (Rosa rugosa, R. wichuraiana, R. setigera, R. laevigata, R. banksiae, R. roxburghii, R. odorata and hybrids) were employed to establish the appropriate nutrient media for shoot multiplication and root initiation of cultured shoots and to describe a procedure for the successful transfer to soil of plants obtained in vitro. Cultured shoot tips and lateral buds from different genotypes proliferated multiple shoots on a basal medium (MS salt, vitamins, glycine, sucrose and agar) supplemented with 0mg/l to 6mg/l 6-benzylamino purine (BA) and 0mg/l to 0.5 mg/l naphthalene acetic acid (NAA). Most rose species cultured in a modified MS medium supplemented with 2mg/l BA showed good growth and shoot proliferation. The buds nearest the apex exhibited the slowest rate of bud development. Root development was enhanced and shoot development inhibited by lowering the concentration of MS salts to quarter- and half-strength. With difficult-to-root species, rooting was improved by supplementing the media with auxin or giving them 3-7days of dark treatment.

High Humidity Environment

The only method for large scale production of pure hybrid seed in Zinnia elegans involves the use of male sterile individuals. The male sterile trait, however, is a three gene recessive which at best produces only 50% male sterile progeny from seed. Since no method of clonal propagation is available, seed-produced female lines require labor intensive field roguing to insure removal of all normal flowered individuals. Clonal micropropagation was investigated as a means of mass producing male steriles for use as female lines. Sterilization procedures were developed for seed and axillary bud explants. Shoot proliferation media containing various levels of BAP, 2ip, and kinetin were screened using in vitro germinated seedling explants of the inbred line `Orange Starlight'. Microshoots demonstrated a high rooting percentage after 2 weeks on basal medium without growth regulators. Plantlets were easily acclimated in 1 to 2 weeks in a high humidity environment. In vitro derived plants of identified male sterile plants were phenotypically evaluated as to their suitability for use in field production.
