In Vitro Propagation of Quercus shumardii Seedlings

by Lisa K. Bennett and Fred T. Davies, Jr.


Abstract:
Single node stem sections of Querus shumardii Buckl. Seedlings wee used to propagate Shumard oak in vitro. Stem sections in liquid woody plant medium (WPM) with 8.9 M (2 mg-liter-1) BA produced the greatest number of shoots 10 mm. The cytokinin 2ip did not promote axillary shoot growth. Shoots were rooted with 73% success under ex vitro conditions in Jiffy-7 peat pellets after a basal dip in 2.5 m (0.5g-liter-1) IBA. Plantlets were acclimatized successfully to greenhouse conditions. Chemical names used: N-(phenylmethyl)-1H-purin-6-amine (BA), N-(3-methyl-2-butenyl)-1H-purin-6-amine (2iP), 1H-indole-3-butanoic acid (IBA), (1,2,4a,4b,10)-2,4a,7-trihydroxy-1-methyl-8-methylenegibb-3-ene-1,10-dicarboxylic acid1,4a-lactone (GA3).
