Chicory(Cichorium intybus L.)의 우량 종근 생산을 위해 파종 시기를 1개월 간격으로 하여 종근 형성 및 화아분화에 미치는 영향을 조사하였다. 화아분화 개시는 4월 파종은 6월 17일, 5월 파종은 7월 2일, 6월 파종은 7월 30일, 7월 파종은 10월 1일에 각각 화아가 분화되었으나 8월과 9월 파종은 전혀 분화되지 않았다. 파종시기별 생육특성에서 $4{\sim}7$월 파종은 종근의 무게가 150g에 도달하기 전에 화아가 분화되어 종근을 이용할 수가 없었으며, 9월 파종은 생육동안 외기온도가 낮아 겨울을 넘기면서 종근이 정상적으로 발육하지 못하는 결과를 보였고, 8월 파종은 파종 후 약 90일이 되는 시기에 Chicon을 생산할 수 있는 종근의 적절한 중량인 200g이상의 이상적인 굴취기에 도달하였으며, 생육기간동안 화아분화가 일어나지 않았다. 따라서 우리나라 기후에 따른 우량 Chicory 종근을 생산하기 위한 적정 파종기는 8월인 것으로 조사되었다.

Abstract

Characteristics of the rootstock formation and flower bud differentiation according to sowing time for production of the high quality rootstock in Chicory (Cichorium intybus L.) was investigated. The flower bud initiation was on the 17th of July after sowing in April, the 2nd of July after sowing in May, the 30th of July after sowing in June and the 1st of October after sowing in July. But they didn't differentiate after sowing in August and September. The days required from germination to flower bud initiation and accumulated temperature depended on the weather. If the outside air temperature was high, the days required were less, If the outside air temperature was low, the days required were greater, the accumulated temperature was similar to the days required in this experement, too. The rootstock sown from April to July wasn't good enough to be use because the flower bud differentiation was generated before harvestable weight. the weight of rootstock was sown in September wasn't heavy enough in weight because the outside air temperature was too low for it to grow well. The plant grows slow and steady through out winter. The rootstock sown in August was havestable 200g in 90 days after sowing before the flower bud differentiated. The best sowing time for the production of high quality rootstock of Chico in the climate of Korea is researched to be August.
