TL;DR: Multiple shoot formation was induced from excised leaf explants of Annona squamosa Linn on a Murashige and Skoog basal medium containing benzylaminopurine and kinetin and the process of development of adventitious buds in leaf culture was analysed histologically.
Abstract: Multiple shoot formation was induced from excised leaf explants of Annona squamosa Linn. (custard apple) seedlings on a Murashige and Skoog basal medium containing benzylaminopurine and kinetin. Various auxins in combination with the above medium produced callusing of the explants. In an investigation of environmental factors affecting shoot induction it was seen that the maximum number of shoots were obtained using the leaf base with petiole at a temperature of 27°C and a light intensity of 1000 lux. Roots were initiated erratically when individual shoots were treated with an auxin and then transferred to an auxin free medium. The process of the development of adventitious buds in leaf culture was analysed histologically.

TL;DR: In this paper, an efficient system was developed from shoot apex explants of finger millet, Eleusine coracana eight genotypes, CO 7, CO 9, CO 13, CO 14, GPU 26, GPU 28, GPU 45, and GPU 48.
Abstract: An efficient somatic embryogenesis and plant regeneration system was developed from shoot apex explants of finger millet, Eleusine coracana Eight genotypes, CO 7, CO 9, CO 13, CO 14, GPU 26, GPU 28, GPU 45, and GPU 48, were assessed in this study The maximum somatic embryogenic induction, at 986%, was obtained from explants cultured on Murashige and Skoog medium supplemented with 180 μM dichlorophenoxyacetic acid and 23 μM kinetin The highest number of shoot induction (26) was observed after transfer of embryonic callus to regeneration medium supplemented with 45 μM thidiazuran and 46 μM kinetin Significant differences were observed between genotypes for somatic embryogenesis and plant regeneration GPU 45 gave the best response, while CO 7 was the least responsive under the culture conditions tested in this study Regenerated plants were successfully rooted and grown to maturity after hardening in soil

TL;DR: In this paper, the authors obtained a fibrillar network on the surface of the somatic proembryos from floret explants of Stevia rebaudiana cultured on MS medium supplemented with 2,4-D and kinetin (0 to 9.29 μM).
Abstract: Somatic embryogenesis was obtained from floret explants of Stevia rebaudiana cultured on MS medium supplemented with 2,4-D (9.05 and 18.10 μM) and kinetin (0 to 9.29 μM). On 9.05μM 2,4-D supplemented medium maximum embryogenic callus formation occurred in medium without kinetin. On 18.10 μM 2,4-D supplemented medium the best treatment was 2.32 μM kinetin. Embryogenic callus started at the base of the corolla and ovary. Histological sections showed a fibrillar network on the surface of somatic proembryos. An unicellular origin of the somatic embryos is proposed. Additional

TL;DR: The determination of chromosome numbers in embryoids, plantlets and regenerated trees reveals that they originate from (poly)haploid pollen grains and aneuploid, triploid and tetraploid cells were encountered in increasing frequencies as the embryoids and plants developed.
Abstract: The yield of pollen embryoids from cultured Hevea anthers was increased 4 fold by optimizing the proportion of ammonium nitrate to potassium nitrate in the dedifferentiation medium. For optimal differentiation of pollen embryoids, kinetin, 2,4-D and α-naphtalene acetic acid are required. Anther culture for 50 days on the dedifferentiation medium is a prerequisite for the selective development of calli and embryoids from microspores.

TL;DR: The results indicated that the highest total dry weight value resulted from the application of IBA and Stimulate®, and that theApplication of mepiquat chloride in association with IBAand BAP reduced total dry matter production.
Abstract: Growth analysis of soybean plants treated with plant growth regulators This work aimed to verify the effect of plant growth regulators on soybean plant growth and chlorophyll content In an experiment carried out in a greenhouse, soybean plants were cultivated (Glycine max (L) Merrill cv BRS-184) in 10-liter pots containing soil from the arable layer, corrected and fertilized according to the soil analysis The treatments used were: control; GA3 100mgL-1; BAP 100mgL-1; IBA 100mgL-1; Stimulate® (IBA, GA3 and kinetin) 20mLL-1; mepiquat chloride 100mgL-1 and mepiquat chloride 100mgL-1 + BAP 100mgL-1 + IBA 100mgL-1 Treatments were applied three times at 30-day intervals Six samplings were taken at 13-day intervals The results indicated that the highest total dry weight value resulted from the application of IBA and Stimulate®, and that the application of mepiquat chloride in association with IBA and BAP reduced total dry matter production The leaf area was smaller than the control in most treatments The chlorophyll content and growth rate were slightly infl uenced by the treatments The cytokinin treatment alone or in association with other plant growth regulators retained the chlorophyll content RGR and NAR decreased from 99 days after sowing with the application of mepiquat chloride
