At the dose rate of 1 ~ 3 gy / min , their tolerant capacity were ranked from high to low as : one year dormant plant > dry dormant seed > one year shoot > wet cold - stratified seed , their irradiation dose were suggested as 75 - 100gy , 50 ~ 100gy , 30 ~ 50gy , 30 ~ 40gy , respectively 在劑量率為1 3gy min時,按照耐受性由高到低依次是:一年生休眠植株休眠干種子一年生枝條解除休眠濕種子。它們的適宜輻射劑量分別是:一年生休眠植株, 75 100gy ;休眠干種子, 50 100gy ;一年生枝條, 30 50gy ;解除休眠濕種子, 30 40gy 。
