Studies on the Merclonal Protocorm of Orchild (IV) Protocorm development from seed embryo

Several days after culture, the parts around suspensor turned brown. In about 10 days the embryo started to form protocorm sending out hairs through seed coat. Around 20 days after culture, most of the protocorms emerged out of seed coat and some of them began to take green color. When observed two months after culture, the protocorn took the characteristic top-shape feature.
