냉장침산잠종(冷藏浸酸蠶種)의 재냉장(再冷藏)이 잠난(蠶卵) 부화(孵化)에 미치는 영향(影響) = Studies on the ability of hatching to the artificial hatching silkworm eggs which restoraged for 20 days (5℃) after treatment

국문 초록 (Abstract)

1. 교잡종의 냉장침산잠종 재냉장적기는 침산 후 48∼72시간 즉 2∼3일이다. 2. 원종의 냉장침산잠종 재냉장적기는 침산 후 72시간 즉 3일이다. 3. 교잡종이나 원종을 막론하고 냉장침산잠종의 재냉장적기는 일언으로써 침산 후 72시간이라고 판단되며 입고방법은 중간온도 보호의 영향력이 있다고 판단된다.

There are many reports concerning to the restoring times, and the range of times are very wide. Author restored the artificial hatching silkworm eggs in ice pit (5℃) two different method; one restored in directly after protected following different times 24 hours, 48 hours and 72 hours of room temperature (24℃), another protected above suggested times and room temperature then indirectly keeping medium temperature (10℃)6 hours. It was incubated in 25℃ temperature after about 20 days of restoring. Pure line and hybrid silk warm eggs are no difference hatching ratio in 72 hours blocks by restoring. Especially good hatching ratio obtained by the medium temperature treatment rather than directly restoring.
