This study aimed to determine an optimal temperature of root zone for the chive cultivation in a greenhouse during the winter season that may raise the possibility of chive (Allium schoenoprasum L.) harvest any time year-round by reducing energy consumption. The maximum and minimum temperatures of root zone were 26.8 and $19.8^{\circ}C$ for the R-Z20, 28.3 and $23.6^{\circ}C$ for the R-Z25 and 22.4 and $14.3^{\circ}C$ for the control. The highest fresh weights of shoot and root, plant height, root length and stem diameter were observed in the R-Z20 treatment. There was no significant difference in the growth between the R-Z25 and control treatment. These results suggest that the optimal temperature of root zone is $20^{\circ}C$ for the chive cultivation in the greenhouse during winter season.

Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa accession 'CBT-Ac77' and cultivar 'Arka Kalyan' were observed to be highly resistant. In vitro inoculation of a selected set of genotypes with A. porri, revealed that 7 days after inoculation was suitable to observe the disease severity. In vitro screening of 43 genotypes for resistance to A. porri revealed two resistant lines. An additional 14 genotypes showed consistent moderate resistance in the field as well as in vitro evaluations. Among the related Allium species, A. schoenoprasum and A. roylei showed the least disease index and can be used for interspecific hybridization with cultivated onion. Differential reaction analysis of three A. porri isolates (Apo-Chiplima, Apn-Nasik, Apg-Guntur) in 43 genotypes revealed significant variation among the evaluated Allium species (P = 0.001). All together, the present study suggest that, the newly identified resistance sources can be used as potential donors for ongoing purple blotch resistance breeding program in India.

본 연구는 향부추의 알뿌리, 잎, 꽃 등의 세 부위별 에탄올 추출물을 대상으로 항산화와 항염 효능을 평가하였다. DPPH와 ABTS 라디컬 소거능 결과, 알뿌리와 잎보다 꽃 추출물의 소거 활성이 높게 나타났으며 FRAP 분석결과 모든 추출물에서 추출물 농도 의존적으로 항산화 활성이 증가하였다. 총 폴리페놀 함량은 꽃 (11.29±0.37 mgGAE/g) > 잎 (6.61±0.14 mgGAE/g) > 알뿌리 (5.7±0.67 mgGAE/g) 추출물 순으로 높게 검출되었다. 쥐 대식세포 RAW264.7 세포와 사람 피부각질 세포주 HaCaT 세포에 대한 세 가지 추출물의 세포독성은 거의 나타나지 않았다. NO비색정량법, ELISA를 통하여 각 추출물의 항염 효능을 조사한 결과 LPS에 의한 NO 생성, TNF-α 분비가 꽃 에탄올 추출물에서 유의한 수준으로 감소하였다. 따라서 이러한 결과들은 천연식물 자원인 향부추의 에탄올 추출물이 화장품 원료로서 높은 가능성을 의미한다.
