Oak mushroom is cultivated using logs and sawdust media as substrates. In this study, fungi were isolated during a monitoring of indoor air in the oak mushroom cultivation houses located in Cheongyang-gun of Chungnam, Geoje-gun of Gyeongnam, Gumi-si of Gyeongbuk, Jangheung-gun of Jeonnam and Yeoju-si of Gyeongggi-do. Identification of the fungi based on morphology and molecular analysis of the internal transcribed spacer region and 28S rDNA, translation elongation factor translation elongation factor 1 a gene, and ${\beta}-tubulin$ gene revealed that six fungi, Cenangium acuum, Neopestalotiopsis surinamensis, Metarhizium marquandii, Periconia macrospinosa, Trichoderma petersenii, and Trichoderma paratroviride that have not been recorded previously in Korea.

As an attempt to determine the identity of the old trees of flowering cherries planted in the yard of the Catholic Archdiocese of Daegu, we conducted comparative phylogenetic analyses between wild and cultivated Prunus yedoensis Matsum. We generated the phylogeny (MP) and haplotype network (TCS) of 25 individuals, including wild P. yedoensis, from Jeju Island, cultivated P. ${\times}$yedoensis 'Somei-yoshino' from Korea and Japan, and P. spachiana f. ascendens (Makino) Kitam. from Jeju Island and Japan based on highly informative sequences of two cpDNA regions (rpl16 gene and trnS-trnG intergenic spacer). The wild and cultivated P. yedoensis were distinguished from each other in both the phylogeny and haplotype networks, and the old flowering cherry trees in Daegu had a cpDNA haplotype identical to that of the cultivated P. ${\times}$yedoensis 'Someiyoshino'. Compared to the cultivated P. ${\times}$yedoensis 'Somei-yoshino', wild P. yedoensis appears to have greater haplotype diversity, presumably originating from the genetic diversity of P. spachiana f. ascendens that functioned as a maternal parent in the hybrid origin of wild P. yedoensis. A future detailed study requires extensive sampling of P. spachiana f. ascendens from Japan and Korea to determine their precise phylogenetic relationships relative to wild and cultivated P. yedoensis. We concluded that the old flowering cherry trees planted in the yard of the Catholic Archdiocese of Daegu are highly likely to be of cultivated origin rather than wild types from Jeju Island, as previously speculated.

소득수준의 향상됨에 따라 환경과 건강에 대한 관심이 높아지면서 유기농산물에 대한 소비자 선호도가 증가하고 있음에도, 유기농산물의 품질에 대한 의구심 등으로 소비확대를 제약하는 요인들은 상존하고 있으며, 특히, 중요 식량자원인 쌀의 경우 유기농 쌀의 식품영양학적 품질 구명 연구는 미진한 실정이다 본 연구는 유기농 쌀의 품질 인증 및 식품영양학적 특성 구명에 기초자료로 활용할 목적으로 오리농법과 관행농법 및 표준시비법(대조구)으로 재배된 추청벼를 현미와 백미로 각각 도정한 후 영양성분 조성을 분석하였고, 동일조건에서 취반한 쌀밥의 관능적 특성을 조사하였다.

지금까지의 논의를 요약하면 sativa 와 glaverrima 는 독립적으로 분화되었고 sativa 중의 indica 와 japonica 도 원시야생종에서 독립적으로 진화되었는데 중국에서는 japonica와 같이 indica 도 진화되었는데 인도에서는 indica 만이 진화되었다. 벼농사의 시작은 1만년전에 불과하지만 벼 자체의 식물학적인 진화과정은 수백만년의 긴 여정이었다. 벼농사가 중국에서 시작되어 우리나라로 넘어오기까지에 5,000 년을 소요했는데 지금까지의 고고학적 증빙으로는 법금 5000-2300년 사이에 한반도 전역에 벼농사는 널리 전파되었다. 한국으로 전래되기까지의 경로와 연대를 추정하기에는 아직 자료가 많이 부족하다 특히 화분화석, 규화석, 고기후학, 고지리학 그리고 황해의 항해에 관한 자료가 아쉽다. Oka 가(1988) 인도부터 중국에 걸친 지역에서 고고학적 연구가 보다더 진전되기까지는 벼의 식물과 재배의 기원을 결정적으로 말할 수는 없을 것이라고 결논한 것은 이런 사정을 분명히 표현한 것으로 생각된다.

As consumer interest in seed sprouts is increasing throughout the world, there is a need to investigate the potential production of leafy sprouts. Three colors of light; white (WRM), blue (BRM), and red (RRM), were studied to evaluate their effects on the approximate compositions of leafy safflower sprouts and their content of vitamin C. The approximate contents of moisture, ash, and total lipids were higher in sprouts grown with RRM than with BRM or WRM; however, crude protein content was higher in sprouts grown with WRM than with BRM or RRM. Chlorophyll content was higher in sprouts grown with RRM than with WRM or BRM, and ascorbic acid content was 157.57 mg% with WRM, 164.64 mg% with BRM and 158.10 mg% with RRM. Our results indicate that cultivation of leafy safflower sprouts under different-colored lights was an effective process for enhancing their nutritional quality.

The yields and the biological efficiency of Hericium erinaceus in the case of the bottle cultivation was 356 g/850 ml, 147.8% and in pot cultivation was 810 g/2,500 ml, 114.3% respectively. On the primordial formation the case of no removing inoculation spawn was well introduced, and the mushroom's yield and biological efficiency was to be high in the case of the bottle's cap was shut. The results in the use of the logs for Hericeum erinaceus's cultural media were to be fine in oak, alder, poplar, black locust in order. And in oak, the yield of the mushrooms were $1195.5\;g/0.1\;m^3$ biological efficiency was 17.3%, the period requirements for primordium was 69 days, and the mushroom's individual weight was 143 g.
