The study of the conditions for the fertilizationin vitro in maize

  • Published:

Abstract

Suitable conditions for the fertilizationin vitro in maize have been studied. The germinating capacity of pollen in synthetic media was low; it was confirmed that it might be stimulated by supplementing agar with egg yolk. Application of pollen onto styles overhanging from the culture medium of excised ovaries was examined. After 5 days the styles could be cut off the ovaries, for the pollen tubes had already penetrated the embryo sacs. However, better results were obtained when cultivating ovaries along with segments of the maize cob. Solid media were more suitable for the development of kernels. Some of them germinatedin situ and gave rise to normal plants. From nucellar meristems of young kernels a callus could be derived which, on further cultivation, became green and regenerated shoots and roots. The cells of meristems exhibited a varying number of chromosomes.
