하이부시 블루베리 ‘블루크롭’의 결과지 세력이 신초와 과실 생장에 미치는 영향

다국어 초록 (Multilingual Abstract)

The aim of this study was to elucidate the influence of vigor of a bearing shoot in ‘Bluecrop’ Highbush Blueberry (Vaccinium corymbosum L.) on growth characteristics of shoots and fruits. Bearing shoots were classified with BS (bearing shoot) and BMB (bearing mother branch). The vigor of bearing shoots were divided into four arbitrary categories; A was thin (< 6.0 ㎜) BMB and short (< 10 ㎝) BS, B was thin BMB and long (≥ 10 ㎝) BS, C was thick (≥ 6 ㎜) BMB and short BS and D was thick BMB and long BS. Shoots from D were longer (6.5 ㎝) and thicker (1.70 ㎜) than those from the others. Shoots of D had more leaves (5.8 ea) than those of the others. Leaf area of D was larger (13.5 ㎠) than those of the others. The first harvest of D was one week faster than the others. Ratio of big berry (> 14 ㎜) from the long BSs was higher (B : 41.7, D : 46.8%) than that from the short BSs. Soluble solid content of small berrys did not show any different according to vigor of bearing shoots, but soluble solid content of big berrys of the long BSs was higher (B : 16.2, D : 15.6 o Bx) than those of the short BSs. The thickness of BMB did not affect ratio of fruit size and soluble soild content. The long BSs would be proper than the short BSs for bearing bigger fruits.
