사과의 접합자배 encapsulation에 의한 인공종자 개발 = Development of Artificial Seeds by Encapsulation Zygotic Embryo of Apple (Malus pumila var. domestica)

다국어 초록 (Multilingual Abstract)

To study for germination rate of apple artificial seeds encapsulated with 2% alginic acids, the rates of germination for artificial seeds of various embryos with partial elimination of cotyledon measured by adding 80 ㎎/L gibberellic acid or/and nutritional media. The germination rate of artificial seeds produced embryo with 3/4 cotyledon (3/4 CE), embryo with 1/2 cotyledon (1/2 CE), embryo with 1/4 cotyledon (1/4 CE), and embryo without cotyledon (NCE) were gradually decreased with compare to normal embryo, but it’s considerably recovered on the alginic acid containing MS solution or/and 80 ㎎/L GA3. In special, the low frequency (55.81%) of germination for artificial seeds of 1/2 cotyledon embryo with alginic acid was increased by treatment with combination of alginic acid, 3% sucrose, and 80 ㎎/L gibberellic acid (98.74%). In case of embryo without cotyledon, the low frequency of embryo without cotyledon (24.44%) in alginic acid almost recovered to 82.45% in alginic acid with MS solution and 80 ㎎/L gibberellic acid. The results shown that the germination of embryo was decreased by the removal of cotyledon, and demonstrated that the low rate of germination could be considerably increased by adding GA3 (80 ㎎/L) or/and nutrition.
