The genus Prunus, belonging to the family Rosaceae, includes a large number of fruit tree species known as “stone fruits” because the seed is encased in a hard, lignified stone-like endocarp.The edible portion of the fruit is the fleshy mesocarp, although the genus also includes nut crop species such as almond (Prunus dulcis Miller) … Webb29 nov. 2024 · Gynogenic haploid regeneration may happen by direct and indirect embryogenesis. During direct embryogenesis, the ovule directly develops into an embryo under in vitro conditions to grow plantlets. When the ovule is induced to form callus that later will differentiate into a whole plant, this is called indirect embryogenesis. css dream jobWebb20 maj 2024 · The Roads to Haploid Embryogenesis Article Full-text available Jan 2024 Kun Shen Mengxue Qu Peng Zhao View Show abstract ...
