남부권역 유망 밀원수종 광나무와 아왜나무의 밀원가치 평가

초록

This study evaluated the honey value by analyzing the secreted nectar volume, and sugar content in the floral nectar of Ligustrum japonicum and Viburnum odoratissimum var. awabuki, promising honey plants in the southern part of the Korea. As for the flowering period, L. japonicum bloomed for 16 days from June 2 to June 17, and the V. odoratissimum bloomed for 10 days from June 8 to June 17. Although the flowering period overlapped somewhat, each of the peak flowering period (flowering rate 30~70%) was different, so it is considered positive in extending the harvesting period. The amount of nectar per flower was secreted with 0.76±0.07 μL/flower of L. japonicum and 0.52±0.08 μL/flower of V. odoratissimum, and both species secreted nectar for two days. The free sugar content (mg/flower) per flower was 0.63±0.09 mg/ flower in L. japonicum and 0.45±0.15 mg/flower in V. odoratissimum. Considering the number of flowers and growth characteristics, the estimated honey production was about 120.4 (103~146) kg/ha in L. japonicum and 125.4 (67~247) kg/ha in V. odoratissimum, respectively. These results show that L. japonicum and V. odoratissimum can be utilized as major honey plants to increase honey production from early to mid-June in the southern part of the Korea.
