Abstract: The present invention relates to methods and systems for obtaining a plantlet from a plurality of somatic plant embryos, and to the use of a compressible and resilient solid substrate comprising a plurality of hydrophilic and biodegradable polymer fibres, as a germination substrate in a method for germination of a somatic plant embryo.

Abstract: An improved baby bottle nipple with a vent comprising a microporous membrane sealed within a membrane holder, which is then inserted into a wall of the nipple. The microporous membrane permits air to pass through to the baby bottle to relieve negative pressure within the bottle but does not permit the liquid within the bottle to leak out of the bottle. The hard material of the membrane holder allows for ease in removing, cleaning, and replacing the vent.
