A sorbent container includes a permeable plastic container, a permeable membrane, and a sorbent. The permeable plastic container includes a sidewall and an endwall, the sidewall defining an opening opposite the endwall. The permeable membrane is fused to the sidewall to cover the opening. A fused junction is formed between the sidewall and the permeable membrane. The sorbent is disposed within the plastic container. This invention provides Methods of conveniently controlling seed germination in genetically modified plants by the administration of a chemical modulator. The plant comprises a hormone-regulating gene placed under the control of a gene switch. A sorbent container includes a permeable plastic container, a permeable membrane, and a sorbent.

El recipiente de plástico permeable incluye una pared lateral y una pared de extremo, definiendo la pared lateral una abertura opuesta a la pared de extremo. La membrana permeable se fusiona con la pared lateral para cubrir la abertura. Una unión fusionada se forma entre la pared lateral y la membrana permeable. El material sorbente está dispuesto dentro del recipiente de plástico.
