Kohlrabi (Brassica oleracea var. gongylodes), with its edible stem tuber formed at the base of the plant stem, presents a valuable source of nutrients. The potential effects of plant growth regulators (PGRs), as well as various concentrations of different sugars on the in vitro development of kohlrabi were studied. Ten-day-old kohlrabi seedlings were cultivated in vitro for 5 weeks at 18?2?C on half-strength MS media containing different concentrations of carbon source such as sucrose, fructose, glucose, xylose and mannitol, combined with or without specific plant growth regulators (N6-benzyladenine (BA), gibberellic acid (GA3), 2,3,5-triiodobenzoic acid (TIBA)). Results showed no tuber formation in all treatments, but growth and development of treated kohlrabi seedlings was significantly affected in a distinctive manner, with a variety of morphological traits being altered in comparison to matching controls.

The Media

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 present study was conducted to improve upon the micropropagation protocol of Rose cultivars by modification of the MS medium through variations in sucrose and agar concentrations thereby enhancing the shoot multiplication and rooting efficiency of the nodal explants. High sucrose concentrations and low agar concentrations favoured shoot mutiplication during the in vitro stages. Enhanced multiplcation and growth was observed on sub culturing the mother explants with regenerated shoots on fresh MS medium containing sucrose (3.5%, w/v) and agar (0.6%, w/v), supplemented with lower concentrations cytokinin combination of BAP and KN (2.5 mgl-1+1.5 mgl-1) respectively. Half strength MS medium containing sucrose (2.0%, w/v) and agar (0.3%, w/v) with NAA and BAP (2.0 mgl-1+0.5 mgl-1) in combination was most effective for rooting.

Caesalpinia pyramidalis is a species endemic to the Caatinga and known popularly as catingueira, which is widely used by local people, mainly for its timber and medicinal and fodder properties. This study investigated the effects of different types and concentrations of plant growth regulators on the in vitro multiplication of C. pyramidalis. In the first experiment, nodal segments were inoculated in media containing different combinations (0.0–8.0 µM) of BAP and NAA. In the second experiment, nodal segments wereinoculated in media containing different types (KIN, BAP and TDZ) and concentrations (0.0–16μM) of cytokinins. We used a WPM medium supplemented with 87.64 mM sucrose and solidified with 7.0 g L-1 agar. After 45 days, the highest number of shoots, leaf number, shoot length and dry mass of shoots were obtained when nodal segments were inoculated into a culture medium without plant growth regulators.
