본 연구는 키위 ‘Halla Gold’, ‘Sweet Gold’ 및 ‘Enza Gold’ 품종에서 꽃가루 품종 및 희석 비율이 과실 품질 및 종자 형성에 미치는 영향을 분석하고자 수행되었다.
1. 화분관은 인공수분 2일 또는 3일 후에 밑씨에 도달하였는데, 그 양상은 꽃가루 품종과 희석 비율에 따라 차이가 있 었다. 화분관 신장은 ‘Halla Gold’와 ‘Sweet Gold’에는 ‘Bohwa’가 ‘Enza Gold’에는 ‘Chieftian’이 좋았으나 ‘Enza Gold’에서는 반대의 경향이었다. 중국산 꽃가루 희석 비율에 따른 화분관 신장은 20배 희석에서 다소 낮은 경향이었다. 2. ‘Hall Gold’, ‘Sweet Gold’ 및 ‘Enza Gold’에서 과중과 건물 률은 ‘Bohwa’로 수분했을 때 높은 경향을 보였다. 종자 수에 있어서 ‘Halla Gold’와 ‘Sweet Gold’에서는 과중과 건물률과 유사한 경향이었으나, ‘Enaza Gold’에서는 반대의 경향을 나타냈다. 3. ‘Enza Gold’에서 중국산 수입 꽃가루 희석비율에 따른 과중 및 건물률은 1~10배에서는 큰 차이가 없이 높은 편이나 20배에서는 가장 낮은 경향이었다. 종자 수 및 100립 중도 유사한 경향이었다.

The study was carried out to evaluate the effect of pollen donor genotype and pollen dilution ratio on fruit quality and seed formation in three yellow-fleshed kiwifruits including ‘Halla Gold’, ‘Sweet Gold’, and 'Enza Gold'. Analysis of pollen tube growth indicated that pollen tubes penetrated into ovules through style 2 or 3 days after artificial pollination, but there was a little bit of difference in the number of pollen tubes penetrating into ovules depending on pollen donor genotypes and dilution ratio. Pollen tube growth of ‘Bohwa’ was better than ‘Chieftain’ in ‘Halla Gold’ and ‘Sweet Gold’, whereas opposite tendency was observed in ‘Enza Gold’. The number of pollen tubes penetrating into ovules was the lowest in 20X pollen dilution. Pollination with ‘Bohwa’ increased the fresh weight and dry matter of fruits than that with ‘Chieftain’ in all three cultivars. Seed number showed a similar tendency to fruit weight and dry matter in ‘Halla Gold’ and ‘Sweet Gold’, but opposite tendency was shown in 'Enza Gold'. The fresh weight and dry matter of fruits was higher in 1-10X compared to that of fruits from 20X dilution and was little affected by dilution ratio. Seed number and 100-seeds weight showed similar tendency to fresh weight and dry matter.
