종자의 휴면타파 및 발아율 향상을 위해, 인위적으로 사용하는 전처리 기술은? | 파종하기 전에 빠르게 그리고 균일하게 발아를 촉진시키고 휴면을 타파하기 위해 종자에 물리적 및 생리적으로 자극을 가하는데 이를 종자 전처리라 한다. 종자의 휴면타파 및 발아율 향상을 위하여 인위적으로 사용될 수 있는 전처리 기술로는 저온처리, 열처리, 화학적 파상처리, 호르몬처리, priming 처리 등이 보고되었다(Khan et al., 1973; Hemmat et al. | |
임목종자의 발아에 필요한 조건은? | 임목종자의 발아는 유전적·환경적 지배를 받는데, 종자가 발아하기 위해서는 알맞은 환경요건이 필수적이다. 발아에 필요한 조건들은 적정 수분, 온도, 공기의 조성, 그리고 광(光)이다. 그 중 온도는 고등식물의 종(種) 또는 개체군(個體群)의 생태적 반응을 지배하며, 특히 종자발아를 제어하는 중요한 환경인자이다(Washitani and Takenata, 1984). | |
갈매보리수나무의 생육이 가능한 조건은? | 열매는 9~10월경에 수확하며 현재 알려진 갈매보리수나무는 6종 12아종으로 분류되고 있다(Rousi, 1971; Li and Schroeder, 1996). 갈매보리수나무는 내한성이 매우 강한 수종으로서 가뭄과 한발에서도 잘 견디며, -43~40℃의 온도분포와 다양한 기후조건, 토양조건에서 생육이 가능할 뿐 아니라, 질소고정능력이 뛰어나 뿌리의 생육이 매우 양호하여 토양침식 예방, 토양개간, 간척 등의 목적에 적합한 식물로 알려져 있다(Baiey and Baiey, 1978). 또한 잎, 열매, 수피 등에서 vitamin, flavonoid, amino acid, 미량원소 등 100여종 이상의 풍부한 유효성분을 포함하고 있어 영양학적 및 생리활성을 활용한 기능성 측면에서도 뛰어난 가치를 인정받고 있다(Geetha et al. |
