초록

본 연구는 '매향' 딸기 런너의 삽목번식시 차광 및 가습에 따른 효과를 확인하기 위하여 수행하였다. 런너 삽수를 2017년 11월 23일에 삽목한 후 대조구(무가습+무차광, C), 무가습+흰색 한랭사 차광 55%(W55), 무가습+검은색 차광막 55%(B55), 무가습+멀칭비닐 차광 100%(B100), 가습+무차광(CH), 가습+흰색 한랭사 차광 55%(W55H), 가습+검은색 차광막 55%(B55H) 및 가습+멀칭비닐 차광 100%(B100H)를 처리하였다. 대조구(무가습+무차광, Control), 무가습+멀칭비닐 100% 차광(Shading), 가습+무차광(Fogging)의 처리를 두고 육묘하였다. 지상부의 생육은 처리간 유의적인 차이가 없었다. 전반적인 지하부의 생육에 있어 가습 처리가 무가습 처리에 비해 우수하였다. 삽목 26일 후 지하부의 생체중과 건물중의 경우 가습+무차광 처리에서 가장 우수하였다. 삽목 26일 후 근장의 경우 가습+흰색 한랭사 차광 55% 처리구 및 가습+검은색 차광막 55% 처리구에서 가장 우수하였다. 이상의 결과를 종합하면 딸기 '매향'의 삽목 번식시 가습 및 차광 유무에 따라 삽목묘의 형태형성에 영향을 주는 것으로 판단된다. 또한 이러한 결과는 삽목번식 방법을 수행하는 다른 작물에도 응용될 수 있을 것으로 판단된다.

This study was conducted to examine the effect of humidification and shading during cutting propagation on growth and development of strawberry (Fragaria x ananassa Duch.) 'Maehyang' plants at a propagation stage. The runner cuttings were stuck on Nov. 23, 2017 in propagation benches set in a Venlo-type glasshouse. Four shading treatments, no shading (control, C), 55% shading with white lawn (W55), 55% black shading net (B55), or 100% black plastic film (B100) with either an intermittent fog system (H) or without fog system. The shading and fog systems were removed 2 weeks after sticking of strawberry cuttings. A nutrient solution for strawberry, which was developed by Yamazaki, was supplied once a day with electrical conductivity (EC) $1.6dS{\cdot}m^{-1}$ and pH 5.8. Growth parameters such as plant height, longest root, crown diameter, leaf chlorophyll, leaf area and fresh and dry weight were measured at 7 days and 26 days after sticking. There was no significant difference in growth of above-aerial part of strawberry. The overall growth of the strawberry roots was better grew by providing fog than that not provide fog. The root fresh weight and root dry weight after 26 days after sticking of strawberry cutting was the best in the treatment that provided fog system without shading (CH). The longest root after 26 days after sticking of strawberry cutting was the best in the treatments that provided fog system with either 55% white lawn (W55H) and 55% black shading net (B55H). These results suggest that morphogenesis of these plants were affected by humidification and shading types. In a broader perspective, these results can be used to optimize studies of other crops grown from cuttings.
