초록
Priming 처리를 통하여 목본종자의 발아반응을 조사하고, 그에 알맞은 priming 유도 물질과 농도를구명하고자 하였다. 35종의 목본종자에 6.7% PEG, 0.1mM GA3, 100mM KNO3, 100mM NaCl를 처리한 결과 모든 처리구에서 발아율이 증가하였고, 그 중 GA3의 처리가 가장 좋았다. 각 처리구에서 공통적으로 발아한 6수종에 대한 발아반응 조사를 시행하였다. 평균발아일수는 KNO3와 GA3 처리구에서 가장 많은 수종이 단축되었다. 발아속도는 GA3에서 가장 빨랐다. 발아치는 GA3가 가장 큰 폭으로 증가하였다. 발아율이 가장 높았던 GA3의 최적농도를 구명하였다. 수종은 발아율이 높았던 3수종과 발아율이낮았던 2수종을 이용하였으며, GA3 농도의 경우 0, 0.01, 0.05, 0.1, 0.5, 1.0mM 농도로 각각 처리하였다. 그 결과 대조구에 비하여 모든 처리구에서 발아율, 발아속도, 평균발아일수, 발아치가 향상되었다. 특히 주요목본 수종종자의 발아에 가장 좋은 GA3 농도는 0.1mM로 나타났다. 본 연구결과는 발아율이 저조한 목본식물종자의 발아율 향상에 기여할 것으로 판단된다.
Abstract
In this study was experiment a germination of woody plants through the priming andinvestigated the optimal priming concentration. 35 kinds of woody seeds treat 6.7% PEG,0.1mM GA3, 100mM KNO3, 100mM NaCl. As a result, all plot has increased germinationpercentage(GP). GA3 was higher than anything else in GP. It investigated for the germinationresponse to six common species to germinate in each treatment. Mean germination time hasshortened in treatments of KNO3 and GA3. GA3 was faster than other in germination rate. TheGA3 increased most significantly in germination value. GA3 that has the best results fromprevious experiments has experiments to an optimal concentration. The species were using threespecies of high germination and two species of low germination. Concentration of GA3 wastested by treatment with 0, 0.01, 0.05, 0.1, 0.5, 1.0 mM. In the Result, all treatment increasedin germination responses better than control, it was most effective using GA3 0.1mM priming. The results of this study are expected to contribute to improved germination poorly woody plantseed germination.
