Abstract BackgroundLeptospermum scoparium J.R.Forst. & G.Forst. is highly valued for the production of antimicrobial honey. Both researchers and the Australian honey industry are interested in the clonal propagation of these plants to be used for experiments and plantation establishment. However, little information is available on clonal propagation by cuttings. Here we sought to develop a detailed method for L. scoparium propagation by semi-hardwood cuttings by testing the influence of genotype and auxin (indole butyric acid (IBA) and IBA + naphthalene acetic acid (NAA)) concentration on plants originating from four natural populations in Victoria, Australia. ResultsThere was no significant difference in root induction, which ranged from 50.9 – 68.0%, in the four clonal source plants selected. The application of 3 g/L IBA increased root induction from 46.6% of the control cuttings to 77.6% of treated cuttings and stimulated longer roots. The application of 8 g/L IBA increased leaf fall, the presence of necrosis, from 22.5% on the controls to 82.8% on dipped cuttings, and cutting death.Although there was no significant difference in root induction, cuttings that were ‘watered-in’ after planting dropped significantly fewer leaves and had significantly lower rates of necrosis than cuttings watered in after 2-3 days. It was also found that the maturity stage of semi-hardwood cuttings did not significantly affect any of the variables measured. Transplant survival ranged from 78.1 – 89.0% for cuttings treated with auxin and 77.3 to 92.2% for the four clonal source plants. ConclusionThis study found that the clonal source plants selected did not affect the success of propagation. Overall for maximum success, semi-hardwood cuttings can be collected from the current or previous seasons growth, be treated with 3 g/L IBA gel, ‘watered in’ and placed into a propagation tent for approximately six weeks. Cuttings that form roots will transplant easily with high transplant survival.

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.

Using fruit branch for pepper shrub propagation is one of alternatives for an efficient pepper multiplication which usually uses underlayer cuttings. This research is aimed at finding the growth response of two pepper (Piper nigrum L.) cuttings to the administration of IBA (Indole Butyric Acid) and NAA (Naphthalene Acetic Acid). This research was conducted at the greenhouse of the Faculty of Agriculture, University of Sumatera Utara, Medan (± 32 m above sea level), from April to August 2017 using a factorial randomized block design with 2 factors, pepper branch cuttings (primary branch cuttings and secondary branch cuttings) and the administration of IBA and NAA (0+0 ppm, 2500+0 ppm, 0+2500 ppm, 1500+1000 ppm, and 1000+1500 ppm). The results show that the emerging shoot rate in the secondary branch cuttings was significantly faster than in the primary branch cuttings, but the volume of root in the primary branch cuttings is significantly larger than in the secondary branch cuttings. There was no significant difference in the administration of IBA and NAA on all observed variables. The highest interaction of shoot length was found in the  primary branch cuttings with the administration of  IBA 1500 ppm + NAA 1000 ppm and the highest percentage of root and root volume was found in the primary branch cuttings with the administration of IBA 2500 ppm + NAA 0 ppm.

Rhizome Biomass

Valeriana jatamansi Jones (Syn. V. wallichii DC.) is an aromatic, medicinal herb used as a tranquilizer and in treating sleep disorders. Rhizome is mainly used to extract essential oil (EO) and valepotriates. High quality and economic yield of rhizomes are available in the third year of growth. Therefore, the cultivation of V. jatamansi is not picking up, and over-exploitation of this plant from wild habitats to meet the increasing demand of the pharmaceutical industry is the cause of threat to the genetic diversity of the species. Further, collections from the wild are heterogeneous, resulting in variable produce. The development of clonal lines can ensure uniform quality and yield of rhizome biomass. An effective clonal propagation method was standardized using different hormonal concentrations of naphthalene acetic acid (NAA) on apical shoot cuttings from the selected clone CSIR-IHBT-VJ-05 for different time durations and raised over various planting media. NAA treatment of 50 ppm concentration for 30 min was found optimum for root induction in apical shoots of V. jatamansi. Variations for EO composition within the clone were non-significant, while samples of the control population were variable. The best quality EO (patchouli alcohol ∼62%) was available during the third year of plant growth. A propagation technique for large-scale quality plant material (QPM) production has been standardized to reduce the stress over natural resources and promote V. jatamansi for use in the aromatic and pharmaceutical industry.

Abstract Background Moringa stenopetala belongs to the flowering family Moringaceae and genus Moringa. It is often referred to as the East African Moringa tree because it is native only to southern Ethiopia and northern Kenya. The expansion of its cultivation and utilization throughout the world especially in Africa is becoming important. For such expansion, the existing propagation method is limiting, so it needs a good propagation system to supply enough planting material with a uniform genotype. Therefore, the main objective of this study was to optimize an in vitro shoot multiplication protocol for M. stenopetala by using shoot tip as explants. Results Shoots were sterilized and cultured on Muraghige and Skoog (MS) medium for in vitro shoot initiation. For multiple shoot induction, the explants were cultured on MS medium supplemented with different concentrations of kinetin (0.5, 1.0, 1.5, 2.0, 2.5 mg/L) with Indole-3- butyric acid (IBA) or α -naphthalene acetic acid (NAA) (0.01, 0.1, 0.5 mg/L) and maintained at 25 ± 2 °C for four weeks. Rooting was achieved by culturing well developed shoots in half-strength MS medium containing IBA (0.1, 0.5, 1.0, 1.5, 2.0 mg/L), NAA (0.1, 0.5, 1.0, 1.5, 2.0 mg/L), and 0.5 mg/L IBA with NAA (0.1, 0.5, 1.0, 1.5, 2.0 mg/L). Statistical analysis revealed that there was a significant difference among all treatments applied in both shoot multiplication and rooting experiments. The maximum number of shoots per explant (3.43 ± 1.41) and 7.97 ± 4.18 leaves per explant were obtained on MS medium containing 0.5 mg/L kinetin with 0.01 mg/LNAA. The highest mean number of roots per shoot (1.63 ± 1.03) and mean root length (0.87 ± 1.22 cm) were obtained on MS medium containing 1.0 mg/LNAA and 0.1 mg/LIBA alone respectively. After acclimatization, 76% of plants were survived in the greenhouse. Conclusion In general, using NAA with kinetin for shoot multiplication was effective than kinetin with IBA. On the other hand, the application of 1.0 mg/L NAA alone and 1.0 mg/L NAA with 0.5 mg/L IBA were more effective for root induction.

Current Status of Saussurea heteromalla was investigated in Galiyat areas of District Abbottabad, viz., Jahaffar, Seri, Beeran Gali, Banj, Haryala, Daryala Gali, Sarbhanna, Barriyan, Akhreela and Broangiala. Saussurea heteromalla was found common in Seri, Sarbhanna and Barriyan; endangered in Haryala, Jahaffar, Banj, Daryala Gali and Beeran Gali and absent in Akhreela and Broangiala. In vitro regeneration of Saussurea heteromalla (D. Don.) Hand-Mazz on MS media was conducted and shoots were developed on full strength MS medium supplemented with 1 mgL-1 GA3. The developed shoots were transferred for root induction to half strength MS medium fortified with various concentrations of Indole butyric acid (IBA) and α-Naphthalene acetic acid (NAA) i.e. T1 (control), T2 (2 mgL-1 IBA), T3 (3 mgL-1 IBA), T4 (4 mgL-1 IBA), T5 (1 mgL-1 NAA), T6 (2 mgL-1 NAA) and T7 (3 mgL-1 NAA). Maximum mean shoot length (6.3 cm), mean number of leaves (7), mean number of nodes (5.25); highest root emergence percentage (71%), means root length (1.5 cm), mean number of roots (3) and highest survival rate (100%) was recorded in treatment T4. However, treatments T5 and T6 also seem to be effective for in vitro rooting of Saussurea heteromalla. Treatments T2, T3 and T7 showed minimum root growth. It was concluded that IBA at higher concentration is more effective for in vitro rooting and better shoot growth of Saussurea heteromalla whereas NAA also initiate rooting but at lower concentration.

Clonal propagation by tissue culture of Afghan pine (Pinuseldarica Medw.) could be useful for improving Christmas tree production and afforestation of semiarid lands in North America. The objectives were (i) to develop organogenesis procedures for clonal propagation and (ii) to evaluate plantlet performance in the field. Shoot production from cotyledon explants was accomplished on solid Shenk and Hildebrandt medium amended with kinetin (11 μM) and benzyladenine (11 μM). Over 100 shoots per clone were obtained with this method. Spontaneous rooting was prevalent in some of the induced shoots. Shoots without root primordia were induced to form roots with naphthalene acetic acid (5 μM), indole butyric acid (10 μM), and benzyladenine (0.22 μM) in 1/2 strength Shenk and Hildebrandt medium. The rate of plantlet elongation in the field was similar to that of seedlings; however, survival of plantlets was lower than that of seedlings. The lower survival of plantlets was directly related to their smaller size at the time of planting. Organogenesis appears to be a very suitable method for mass micropropagation of this environmentally and economically useful tree.

Lilium candidum L. is one of the most fragrant plant species among Liliaceae. The indigenous and natural populations of L. candidum are significantly affected by fast increasing anthropological population pressure and increased carbon fuel pollution. There is a necessity for development of a micropropagation protocol to serve in effective manner for both commercial multiplication and protection of the plant. The study targeted to develop a strategy for effective in vitro plant propagation system using static liquid culture, seismomorphogenic treatments with mixed liquid culture and semi solid culture medium using single scale explants. The former two techniques failed to regenerate new bulblets effectively whereby the later technique induced 100% regeneration on all treatments. Maximum number of bulblets regenerated on 0.27 µM Thidiazuron + 1.08 µM Naphthalene acetic acid. The scale explant could be recultured and regenerated on the mother culture medium for six cycles. The daughter bulblets regenerated on Murashige and Skoog medium containing both 0.18 or 0.27 µM TDZ + 1.08 µM NAA were successfully rooted using 1/2 × MS medium containing 2.45 µM indole butyric acid. Regardless of rooting development, acclimatization was noted on all bulblets in the greenhouse. These plants are showing continuous flowering since last four years under hot-summer Mediterranean (CSa type) climate field conditions of Tekirdag province of Thrace region in Turkey.   ********* In press - Online First.

The experiment was carried out to study the effect of genotypes and growth regulators on root induction and shoot regeneration of brinjal (Solanum melongena) genotypes. Leaf segments of three varieties of Solanum were cultured on MS medium with different concentrations and combinations of plant growth regulators. Among the tested genotypes, Protab showed highest percentage of shoot regeneration (65.67%). Early and maximum rate of regeneration was found in MS + 1 mg/L NAA (naphthalene acetic acid) + 0.1 mg/LBAP (6-benzylamino purine) for all the genotypes. The highest number of roots per shoot was counted in Protab (73.33%) on ½MS + 2 mg/L IBA (indole butyric acid) + 0.4 mg/L BAP. Based on the overall performance, the variety Protab appeared as the best for shoot and root formation and ultimately successful regeneration of plants.Res. Agric., Livest.

Andrographis paniculatais one of the most important therapeutical herbs, widely used in traditional medical systems for the treatment of diverse diseases for thousands of years. This study was carried out to assess the effect of 1-naphthaleneacetic acid (NAA) on adventitious rooting inA. paniculatashoot cuttings. The cuttings were treated with six concentrations of NAA (0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 mM) by applying soaking method and cuttings without hormone (soaking in distilled water) were considered as control. The cuttings were then inoculated into peat moss in the planting tray and incubated under complete shade for root induction. Water was sprayed on peat moss once daily to moisten it. The results showed that different concentrations of NAA significantly (P≤0.05) affected the rooting characteristics ofA. paniculataand 2.5 mM of NAA was found to be more effective to induce rooting in young apical shoot (YAS) cuttings compared to other concentrations and old apical shoot (OAS). This study also postulates that adventitious rooting response depends on the juvenility of plant material and concentration of growth regulator. This report describes a technique for adventitious rooting inA.paniculata, which could be feasible to use for commercial scale propagation of this plant.
