Figure 2.
Effects of partial desiccation treatment (PDT) on the germination of P. asperata somatic embryos. (a) The germination rates of embryos after PDT for different times. Mean ± SD, n = 5. Significant differences are indicated by different letters (P < 0.05). (b) Photograph of embryos germinating without PDT. Most of the germinants were abnormal with clear hyperhydricity and poor radicle development. (c) Photograph of embryos germinating after 14 days of PDT. The germinants were strong with well‐developed roots and shoots.
