To initiate somatic embryogenesis in Pinus sylvestris and Pinus pinaster, immature seeds
were collected from June to August and the developmental stage of the zygotic embryos was …

Embryogenic tissue was induced from embryonic explants of Pinus patula, using intact
female gametophytes containing immature embryos. Cone collections were carried out …

Embryogenic calli were initiated from embryonic explants of Pinus roxburghii using female
gametophytes containing immature pre-cotyledonary embryos. Zygotic embryos were …

The effect of plant growth regulators (PGR), 6-benzyladenine (BA), 2, 4-
dichlorophenoxyacetic acid (2, 4-D), α-naphthaleneacetic acid (NAA) and sugars (sucrose …

Low initiation frequency is one of the main barriers in applying somatic embryogenesis to
the clonal production of Pinus species. Factors affecting initiation, including basal medium …

Embryogenic tissue from six genotypes of Pinus patula (Schiede et Deppe) was subjected to
a number of treatments to improve both somatic embryo maturation and germination …

Embryogenic cultures were derived from immature zygotic embryos of Pinus nigra Arn. The
zygotic embryos at the time of collection were at the precotyledonary stage of development …

Several factors affecting somatic embryogenesis (SE) in Pinus sylvestris from self-and cross-
pollinated seed families were studied with the aim of producing large quantities of clonal …

Embryogenic callus was initiated from cultured Pinus patula Scheide. et Deppe.
megagametophyte explants containing immature zygotic embryos. A average of 2.6% of the …

Somatic embryogenesis (SE) initiation in Pinus strobus was optimized by the manipulation
of plant growth regulator (PGR) concentrations in the culture medium. Modified Litvay …
