삽목용 토양과 삽수 길이 및 굵기에 따른 몇 가지 하이부시 블루베리 품종의 녹지삽 생육 및 생존율 차이 Growth and Survival Rate of Softwood Cuttings Influenced by Bed Media, Cutting Length and Thickness on Several Cultivars of Highbush Blueberry
본 실험은 blueberry 주요 품종을 대상으로 여름철에 효과적인 반숙지 삽목법을 확립하고자 수행하였다. ‘Bluegold’(71.5%)와 ‘Bluejay’(52.8%)는 peatmoss와 sand의 혼용구(4:1)에서 Sharpblue(85.5%)는 peatmoss 단용구에서 삽수의 생존율이 높았고, 일반상토, perlite, 그리고 vermiculite를 혼합한 배양토에서는 생존율이 낮았다. 삽수의 길이와 굵기가 blueberry 발근에 미치는 영향을 알아보는 실험에서는 ‘Sharpblue’는 삽수의 장단에 관계없이 71.3% 이상의 높은 발근율을 보였다. ‘Bluegold’는 8-12㎝구가 66.7%의 발근율을 보여 14-18㎝ 구보다 발근율이 현저하게 높았으며, ‘Bluejay’도 이와 유사한 결과를 보였다. ‘Sharpblue’는 4.5-6.0㎜의 삽수구에서 2.5-3.4㎜ 삽수구에 비해 우수한 생존율 및 발근을 나타냈다. 이 같은 현상은 ‘Bluegold’에서도 유사하였으나 ‘Bluejay’에서는 반대의 경향을 보였다. 2007년에는 가는 삽수의 생존율이 높았는데 이는 삽수용 신초가 자라는 시기와 장마가 겹쳤기 때문으로 판단된다. Blueberry의 녹지삽용 삽수는 6월말 경화가 진행되고 굵기가 확보된 줄기에서 기부와 정부를 제외하고 가지를 짧게 잘라 이용하는 것이 발근과 생존율에 유리한 것으로 생각된다.

Softwood cuttings were conducted to establish an efficient propagation method of highbush blueberry grown in shaded glasshouses during summer from year 2005 to 2007. When the cuttings were planted in peatmoss:sand (4:1) media survival rates of ‘Bluejay’ and ‘Bluegold’ were 52.8 and 71.5%, respectively. ‘Sharpblue’ was 85.5% when the cuttings were planted in peatmoss media. Growth and rooting were significantly improved when peatmoss was used as a major component of media comparing to combination of common bed soil, perlite, and vermiculite. Length of cuttings affected the survival rate, too and those for short cuttings (8-12 ㎝) and long cuttings (14-16 ㎝) of ‘Bluegold’ were 66.7 and 49.3%, respectively. ‘Bluejay’ cuttings showed the similar tendency, while the length of cuttings did not affect the survival rate of ‘Sharpblue’. Improved rooting and consecutive growth was found when thick cuttings were used for ‘Sharpblue’ and ‘Bluegold’ and thin cuttings were used for ‘Bluejay’. Results indicate that the survival rate, rooting and consecutive growth for softwood cutting were improved when shoot and thick cuttings were used the conditions of the present study.
