Abstract

The experiments were conducted to determine the factors such as light and darkness, phytohormone and seed coat, influencing on seed germination of Bidens tripartita L. and B. frondosa. The seeds of both species were germinated when seed coat was damaged and weakened. $GA_3$ and BA stimulated germination of both species but ABA and IAA had no effect on germination of them, which ranged 50.0% to 80.0%. In B. forndosa, when inner layer of seed coat was removed, germination was highly promoted up to 96.7% compared with 10.0% germination rate in another treatments.

가막사리와 미국가막사리 종자의 발아에 명 암조건과 식물생장조절제(ABA, BA, $GA_3$, IAA) 및 종피가 미치는 영향을 조사하였다. 1. 종피를 파상시킨 종자는 명상태에서는 발아하였으나, 암조건에서는 발아하지 않거나 저조하였다. 2. 종피를 파상시킨 가막사리와 미국 가막사리 종자는 암조건에서는 발아하지 않았으나 $GA_3$와 BA의 처리에 의해 발아가 가능하였다. 3. 미국가막사리 종자의 외피만 제거할 경우 발아되지 않았으나 내피를 제거할 경우에는 높은 발아율을 나타내었다.
