Abstract

The experiment was conducted at the growth chamber to determine germination, seedling growth and fresh weight between the untreated control and iron-coated seeds in germination test of the rice seeds. There was of 95% germination in rice seeds regardless of treatments and days for seedling emergence was relatively 13-14days. Seedling height was 4.9cm of the iron-coated seeds but 0.4cm of the untreated control and there was 6.S roots of seedling in iron-coated seeds and 5.5 roots of seedling in the untreated control, respectively. The fresh weight of seedling was 107mg of the iron-coated seeds and 66mg of the untreated control at 35days after sowing.

Growth Chamber에서 철분코팅 벼종자와 무처리 볍씨의 발아 및 입묘 특성을 구명하기 위하여 유묘의 입모율, 경시적 입묘양상의 변화, 초장, 엽수, 근장, 근수, 생체중의 특성을 조사결과를 요약하면 다음과 같다. 1. 입모율은 철분코팅 95%, 무처리 95%로 매우 높은 결과를 보였으며, 벼 출아소요일수는 출아가 13~14일 소요되는 것으로 나타났으며, 철분코팅볍씨가 무처리 볍씨보다 전반적으로 출아가 빠르게 나타났다. 2. 벼 유묘의 초장에서는 철분코팅볍씨 4.9cm, 무처리볍씨 3.4cm로, 엽수는 철분코팅볍씨 3.8개, 무처리볍씨 3.3개로 각각 나타났다. 3. 유묘의 뿌리 철분코팅볍씨 3.8cm로 무처리볍씨 0.4cm보다 9.5배 최장 뿌리 길이가 긴 것으로 나타났으나, 뿌리수는 철분코팅볍씨 6.8개, 무처리볍씨 5.5개로 비슷한 수준으로 나타났다. 4. 유묘의 생체중은 철분코팅볍씨 107mg, 무처리 볍씨 66mg로 각각 나타났다.
