Abstract: According to the invention an embryogenic cell mass is cultured with a culture medium comprising an anti-auxin resulting in an unexpected shift in physiology from proliferation to maturation. Proliferation is reduced so that the formation of new immature embryos ceases. Reduction of proliferation facilitates the transition from proliferation to maturation and maturation frequency is increased to a much larger extend than expected. Surprisingly, it has been discovered that the quality of the somatic embryos is not reduced, although the activity of the important endogenous plant growth regulator, auxin, is reduced. As a mater of fact, the overall quality of the mature embryos harvested at the end of maturation is actually increased over the prior art.

Abstract: A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘White Robe’ originated as a cutting taken from the cultivar ‘Buffie’. The cultivar ‘White Robe’ has white sepals at maturity and is distinguished from other similar cultivars of which the inventor is aware by the unique manner in which the inflorescence ages. As the mature sepals age and turn green they are highly resistant to burning and turning brown The new variety ‘White Robe’ further possesses the favorable characteristics of a compact growth habit and long lasting large inflorescences.
