TL;DR: Ovules of Populus deltoides were isolated from developing capsules and cultured on woody plant medium containing a vitamin mixture supplemented with cytokinins, 6benzylaminopurine and 2eatin to investigate shoot initiation and development from immature embryos and expanded cotyledons after 1 month in vitro culture.
Abstract: Ovules of Populus deltoides were isolated from developing capsules and cultured on woody plant medium (WPM) containing a vitamin mixture supplemented with cytokinins, 6benzylaminopurine (BAP) and 2eatin. Multiple shoots were obtained with immature ovules after 20 days from pollination. Generally, zeatin was better than BAP in inducing multiple shoots. The highest average number (56.1 ± 7.4) of shoots was produced from the immature ovules of 20 days post-pollination on WPM medium supplemented with 5.0 mg/1 zeatin. The average percent of in vitro germination was over 96,6 ± 4.2 % with the immature ovules of 20,26, and 32 days post-pollination on BAP and zeatin. Roots were formed after small clumps of shoots were transferred to half strength medium containing IBA 0.02 mg/1. A survival rate of 97% was achieved during the transfer of plantlets to a greenhouse environment. Light and scanning electron microscopes were used to investigate shoot initiation and development from immature embryos and expanded cotyledons after 1 month in vitro culture.

TL;DR: The higher activity of thiozeatin than zeatin in this system may reside in the resistance of thIOzeatin to enzymatic attack, as P. vulgaris tissues contain an enzyme system capable of cleaving off unsaturated side chains of cytokinins.

TL;DR: Adventitious plants regenerated from mature hypocotyls of persimmon cv. Jiro have been got, with the rate of shoots regenerated being 33.3% when cultured on the half NH4 + of MS medium supplemented with zeatin 1.5mg/L,IAA 0.01mg/
Abstract: Adventitious plants regenerated from mature hypocotyls of persimmon cv. Jiro have been got,with the rate of shoots regenerated being 33.3% when cultured on the half NH4 + of MS medium supplemented with zeatin 1.5mg/L,IAA 0.01mg/L for 3 weeks in the dark and then exposed to light,and with rooting rate being 78% when cultured on 1/2 MS+IBA 0.3mg/L+sucrose 2%.

TL;DR: The stagheads in Brassica juncea vars showed lower levels of indole-3-acetic acid and higher levels of gibberellic acid, zeatin and abscisic acid as compared with healthy inflorescences.
Abstract: The stagheads (malformed inflorescences) in Brassica juncea vars. RL-1359, RLM-619 and Brassica campestris var. TL-15 caused by Albugo Candida (Pers. ex Lev.) Kuntze showed lower levels of indole-3-acetic acid and higher levels of gibberellic acid, zeatin and abscisic acid as compared with healthy inflorescences.
