Notes: Solute Absorption by Seeds of Sugar Maple
Abstract:Sugar maple seeds were soaked in 0.5 percent (w/v) aqueous solutions of acidic and basic compounds varying in molecular weight from 100 to 880. In general, only basic compounds penetrated the seeds. The effects of growth regulators on germination was also tested by soaking seeds and fruits in 2 and 10 g/ml solutions of abscisic acid, gibberellic acid, and indole acetic acid prior to germinating them. Results of this study suggest that solute absorption by these seeds is not related to molecular weight but rather to the acid-base properties of the solute. Forest Sci. 24:509-512.
