Abstract
본 연구는 국내 육성 품종 ‘선플’과 ‘감황’ 과실 생산에 적합한 수분수를 선발하기 위해 ‘SKK2’, ‘델리웅’, ‘보화’, ‘Chieftain’ 각각의 꽃가루로 인공수분하여 과실 품질과 종자의 발육을 조사하였다. 착과율은 두 품종이 모든 처리구에서 96% 이상이었다. ‘선플’은 ‘델리웅’ 처리에서 과중이 가장 높았고 2021년은 ‘보화’ 처리에서 2022년은 ‘Chieftain’ 처리에서 가장 낮았다. ‘감황’은 2021년에 ‘델리웅’ 처리에서 2022년은 ‘Chieftain’ 처리에서 과중이 가장 높아 연차 간 차이를 보였다. ‘선플’의과실 품질 조사 결과, 2022년에 건물률은 ‘SKK2’처리에서가장 높고 가용성 고형물 함량은 ‘Chieftain’에서 가장 높았으며 2021년에는 처리 간 유의차가 없었다. ‘선플’의 총 종자 수와 미숙 종자 수는 6배체 수분수 처리구에서 가장 많았고 천립중은 4배체 수분수 처리구에서 무거웠다. ‘감황’의 과실 품질조사 결과, 건물률과 산 함량은 2년 모두 ‘SKK2’ 처리에서 가장 높았고 가용성 고형물 함량은 연차 간 차이를 나타냈다. ‘감황’의 총 종자 수와 성숙 종자 수는 ‘델리웅’과 ‘Chieftain’ 처리에서 가장 많았고 미숙 종자 수는 ‘SKK2’ 처리에서 가장 적었다.
This study aimed to assess the characteristics of fruit quality and seed formation resulting from pollination by four different pollen donors: ‘SKK2’, ‘Deliwoong’, ‘Pohwa’, and ‘Chieftain’. The objective was to identify the most effective pollen donor for yielding commercially viable fruits in two cultivars of kiwifruit (Actinidia chinensis var. chinensis): ‘Sunfl’ and ‘Garmhwang’. Over a two-year period, the fruit setting rate for ‘Sunfl’ and ‘Garmhwang’ kiwifruit, pollinated by the four donors, consistently exceeded 96%. For ‘Sunfl’, the heaviest fruit weight was observed when pollinated with ‘Deliwoong’ for both years, while the lightest fruit was associated with ‘Pohwa’ in 2021 and ‘Chieftain’ in 2022. For ‘Garmhwang’, there was a yearly variation with the heaviest fruit weight linked to ‘Deliwoong’ in 2021 and ‘Chieftain’ in 2022. When examining the fruit characteristics of ‘Sunfl’, the dry matter content was highest when pollinated by ‘SKK2’, and the soluble solids content peaked with ‘Chieftain’ in 2021, although no significant differences were observed in 2022. Total and immature seed numbers in ‘Sunfl’ were highest with hexaploid pollen donors, while the 1000-seed weight was highest with tetraploid pollen donors. For the fruit characteristics of ‘Garmhwang’, the dry matter content and titratable acidity were highest when pollinated by ‘SKK2’. Soluble solids content showed annual variation. Mature and total seed number in ‘Garmhwang’ were highest with ‘Deliwoong’ and ‘Chieftain’, while the immature seed number was lowest with ‘SKK2’.
