Figure 2: Shrubbiness development (multiple stems directly from the same radicle) of three Quercus species after a month-long soaking of the bulk acorns in an amount of water just adequate water to cover all acorns for about a month.
From: Endocidal Regulation of Secondary Metabolites in the Producing Organisms
(a) 7.3% of the seedlings germinated from the treated acorns of Quercus shumardii developed shrubbiness. (b) 8.6% of the seedlings germinated from the treated acorns of Q. texana developed shrubbiness. (c) 19.3% of the seedlings germinated from the treated acorns of Q. michauxii developed shrubbiness.
