Induction of embryogenesis from isolated apple microspores
Plant Cell Reports, 1999We report, for the first time, the induction of embryogenesis and plant formation from isolated apple (Malus domestica Borkh.) microspores in vitro. Different isolation techniques were tested and an optimized protocol was elaborated. Furthermore, the influence of the induction medium and starvation treatment, using different starvation material ...

Influence of ethylene in microspore embryogenesis
1996Ethylene (C2H4) is the simplest olefin and exists in the gaseous state under normal physiological conditions; it regulates many aspects of plant growth, development and senescence and its effects are commercially important (Yang and Hoffman, 1984). Some of the physiological processes influenced by ethylene are release of seed, bud dormancy, seedling ...

Evidence for microspore embryogenesis in wheat anther culture
In Vitro Cellular & Developmental Biology - Plant, 1991In wheat, plants may be regenerated from microspores via direct embryogenesis or organogenesis or embryogenesis from callus. Light and scanning electron microscopy were used to carefully study morphogenesis of microspore-derived plants from anther culture on modified 85D12 starch medium and to determine whether the plants were formed via organogenesis ...

Microspore Embryogenesis Induced by Low Gamma Dose Irradiation in Apple
Plant Breeding, 1992AbstractFlower buds and extracted anthers of two apple genotypes, ‘Golden Delicious’— a previously known non‐androgenic genotype — and ‘Topred’— a known androgenic genotype —, were irradiated by gamma‐rays at doses ranging from 5 to 20 Gy, after 0 to 5 weeks of cold pre‐treatment (3 °C).

Microspore embryogenesis inCitrusand other fruit crops
Acta Horticulturae, 2017Conventional methods, involving several generations of selfing, are not applicable to produce homozygous lines in Citrus as well as in the other fruit crops, due to the high heterozygosity of the genomes, the long duration of the generation cycle, the large size, and, often, the self-incompatibility. For this reason, there is no different way to obtain
