Other claims from this paper (6)

Observation Norway spruce embryogenic lines are initiated from zygotic embryos.
Intervention effect Norway spruce cell lines proliferate as PEMs with auxin and cytokinin.
Intervention effect Early somatic embryos develop from PEMs after auxin and cytokinin withdrawal.
Mechanism The PEM-to-embryo transition determines mature embryo yield and quality.
Intervention effect Embryos develop to late embryogeny in the presence of abscisic acid.
Observation Some spruce cell lines have developmental arrest at certain stages.

Control of Wild Carrot Somatic Embryo Development by Antioxidants

Brent A. Earnshaw; Morris A. Johnson PLANT PHYSIOLOGY 1987. doi:10.1104/pp.85.1.273

Other claims from this paper (7)

Intervention effect Ascorbic acid suppressed wild carrot somatic embryogenesis with little biomass effect.
Intervention effect Vitamin E suppressed wild carrot somatic embryogenesis with little biomass effect.
Observation GSSG reductase activity was higher in proliferating than developing cultures.
Observation Dehydroascorbate reductase activity did not differ between cultures.
Association GSH and AA concentrations were governed by 2,4-D.
Mechanism Redox status was interpreted as a determinant of proliferative versus developmental growth.
Mechanism The authors propose that 2,4-D may act partly through endogenous antioxidant levels.
