Melia azedarach L. is one of the important plants because it’s a good source of natural compounds thathave insecticide and antimicrobial effect. The main aim of this research is to investigate the effect of explants source and plant growth regulators on in vitro callus induction and regeneration of organs from it. Callus was induced from nodes, internodes from one-year-old seedlings and seeds of Melia plant by culturing them on MS medium supplemented with α-naphthalene acetic acid (NAA) 0.0, 0.1, 0.2, 0.3, or 0.4 mg/L and 6- benzyl adenine (BA) 0.0, 1.0, 2.0, 3.0, or 4.0 mg/L, then shoot regeneration from callus was occurred. Results showed that there was a different response from explants towards callus induction and adventitious shoots formation according to plant growth regulators combination. Seeds gave superior percentage for callus induction 24.4% compared with node and internode 15.6, 12.8% respectively. Combination of 0.3 mg/L NAA + 3.0 mg/L BA was the best for callus induction in all explants 86.6% . Shoot regeneration was achieved in 0.3 mg/L NAA + 4.0 mg/L BA and 0.4 mg/L NAA + 4.0 mg/L BA for callus from seeds and internodes respectively, while the combination 0.3 mg/L NAA + 3.0 mg/L BA or 0.4 mg/L NAA + 3.0 mg/L BA was the best for node callus. The shoots were rooted well in MS + 0.25 mg/L NAA . Rooted plantlets were acclimatized in small plastic pots filled with peat moss: river soil (1 :1 v/v ), then transferred to the soil.

MR 219, an indica rice from a cross between MR 137 and MR 151 is a long-grain rice variety of high-yielding, good quality of shape and taste, short maturation as well as resistance to blast and bacterial leaf blight. However, it is regarded as a recalcitrant variety due to its low ratio of callogenesis and regeneration in in vitro culturing. This would be a hindrance to crop improvements such as genetic transformation and other crop improvement methods. The objective of this study was to optimize the concentrations and combinations of plant growth regulators (PGRs) which were 2,4-Dichlorophenoxyacetic acid (2,4-D), Kinetin (KIN) and Naphthalene acetic acid (NAA) on its callus induction that ranging from 0.5 to 15.0 mg/L. The callus was induced from the mature seeds of MR 219 on the Murashige and Skoog (MS) media supplemented with 4.4 g/L of MS powder with vitamins, 30.0 g/L of sucrose and 3.5 g/L of gelrite with the addition of 2,4-D, KIN and NAA in different concentrations and combinations. All media supplemented with 2,4- D had successfully induced the callus and 2.0 mg/L of 2,4-D was the best concentration for the callus induction with a 100% success rate. The addition of 15.0 mg/L of NAA, provided less time taken for callus induction with better callus morphology which resulted in fewer browning problems.

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.

In vitro: regeneration of Chenopodium quinoa Willd. was achieved from cotyledonary nodes explants. In this study, used 6-Benzylaminopurine (BAP) and α-Naphthalene Acetic Acid (NAA) of plant growth regulators with different concentrations individually as well as in combination and used different concentrations of sugar (sucrose) with different concentrations. For was rooting, used half strength (½MS), full-strength MS and ½ MS supplemented with 0.2 mg/l of NAA. The results mentioned, explant responding (%) to multiplication was about 73% for all BAP treatments compared with control and average numbers of shoot increased with increased BAP concentration except 5 mg/l of BAP. The highest explant responding (%) was in media supplemented BAP without NAA compared other treatments noted that the media with combination of BAP and NAA gives formation of callus in bases of the plantlets. Also, the result inducted the combinations between (BAP–NAA) was highly significantly (P≤ 0.001) and less effective on number of shoots where the highest number of shoot was 3.40 in media with 3 mg/l BAP compared other treatments. The highest of explant responding 93.33% was in media supplement with 10 g/l sucrose and (10 g/l sucrose + 3 mg/l BAP), but sucrose level for good greening and developed shoots (4 shoots) was in medium supplement with 10 g/l sucrose. The shoots rooted well on half-strength MS medium with 60% percentage of root. The rooted shoots were acclimatized and transferred to green house to follow their development.

The aim of this work was to assess the regeneration capacity of Amelanchier alnifolia var. cusickii and Lonicera kamtschatica cv. ‘Jugana’ from different types of explants under various hormonal treatments. The whole leaves, petioles, and internodal segments of in vitro plants were examined as explants. Several plant growth regulators (cytokinins and auxins) were evaluated for their ability to induce adventitious regeneration. Direct and indirect organogenesis was achieved under certain culture conditions in both species. The frequency of shoot regeneration was strongly dependent on concentrations of plant growth regulators in the induction media (L.kamtschatica ‘Jugana’) or concentrations of plant growth regulators in the induction media and type of explant (A. alnifolia var. cusickii). Results showed that leaves were not suitable explants for A. alnifolia var. cusickii. Both species were able to regenerate shoots from internodal segments and petioles. The highest induction of shoots was obtained on Murashige and Skoog (MS) medium enriched with 2 mg/L thidiazuron (TDZ) and 0.5 mg/L indole-3-butyric acid (IBA) for Amelanchier alnifolia and with 1 mg/L TDZ and 0.2 mg/L indole-3-acetic acid (IAA) for L. kamtschatica ‘Jugana’. Obtained adventitious shoots were further proliferated in order to investigate their multiplication capacity. The multiplication of shoots was successful in all cultivars, with the best results reported in A. alnifolia var. cusickii (7.07 shoots/explant on average).

Jatropha (Jatropha curcas L.) is an oil bearing crop growing in tropical and subtropical parts of the world. The present study was undertaken to investigate the effects of different plant growth regulators on in vitro callus induction in physic nut (J. curcus). In the present study, it was observed that all the explants viz., leaf lamina, petioles, nodal segments and cotyledonary nodes showed good callus induction responses on various culture media thus tried. Leaf lamina and petioles showed 100.0% callus induction responses on different MS media supplemented with auxins and cytokinins alone or in combinations whereas, nodal segments and cotyledonary nodes showed maximum 89.6% and 83.9% callus induction respectively. The presence of 2, 4-D in culture media with auxins or cytokinins was essential for good callus growth. Among different explants tried, leaf lamina was the best responding explants and MS-13 media supplemented with 5×10-6 M NAA and 10-5 M 2, 4-D is the best callusing and growth supporting medium. However, the regenerative competence of the callus tissues can differ depending on the type of explants used because certain types of plant tissues have more favorable regeneration responses than others. Callus induction rate from all explant types was highest than other reports. The results obtained in the present study would facilitate the high callus induction and regeneration responses in J. curcus for its improvement using biotechnological tools.
