Abstract

This study was carried out to find out the best methods of raising transplants and to evaluate the possibility of reducing incidence of basal stem rot caused by Pythium myriotylum and of easiness for seed tuber production of potatoes (Solanum tubersum L.) grown in aeroponics system. Incidence of basal stem rot, growth and yield of transplants raised from stem cutting, non-rooted cutting, non-rooted cutting with a wick, deep flow rooted cutting, and rooted mini tuber were evaluated in a spring season of 2002. Potato basal stem rot occurred 11% in transplants raised from stem cutting but did not occur in the other transplants. Stem length averaged about 60.0 cm except for transplants raised from stem cutting with 48.3 cm. Transplants raised from deep flow rooted cutting had the heaviest root dry weight, 33.2 g per plant, followed by those from rooted mini tuber. The number of first stolons per plant was greatest as twelve stolons for transplants raised from deep flow stem cutting and rooted mini tuber. Transplants raised from deep flow stem cutting had 773 total tubers and 491 tubers over 5 g per m2, which is the greatest among the treatments. Transplants raised from rooted mini tuber was ranked second for the number of total tubers and tubers over 5 g. Transplants raised from stem cutting produced fewest tubers over 5 g, that is 255 tubers per m2, but the highest number of tubers weighing 5 g or less, that is 365 tubers per m2. These results indicate that raising transplants from deep flow stem cutting could be best considering basal stem rot incidence and tuber yield of potatoes grown in aeroponics system.

상위단계 씨감자의 안정적인 공급을 위해 분무경 양액재배 경삽묘에서 발생되는 줄기기부썪음병의 발생을 줄이고, 묘 생산단계를 간소화하면서 급속증식묘를 찾고자 봄재배에서 줄기꺾꽂이묘(경삽묘), 무발근묘, 심지 무발근묘, 경삽담액묘, 소서발근묘 등을 이용하여 줄기기부썩음병 발생률, 생육특성, 수량 등을 조사하였다. 줄기기부썩음병은 경삽묘정식구에서 11%였으나 다른 처리구에서는 전혀 발생하지 않았다. 경장은 48.3cm이었던 경삽묘정식구를 제외한 다른 처리구에서는 60.0cm 내외로 유의한 차이가 없었으며 건근중은 경삽담액묘정식구에서 33.2g으로 가장 무거웠고 그 다음이 소서발근묘정식구였다. 주당 1차복지수는 경삽담액묘와 소서발근묘정식구에서 12개 이상으로 많았고 최장 복지 길이는 경삽담액묘정식구에서 78.5cm으로 가장 길었다. 총괴경수와 5g 이상 괴경수는 경삽담액묘정식구에서 각각 m2당 773개와 491개로 가장 많았고 다음은 소서발근묘였으며, 경삽묘정식구에서는 5g 이상 괴경수가 m2당 255개로 가장 적었으나 5g 이하 괴경수는 m2당 365개로 가장 많았다. 따라서 분무경 양액재배에서 일시수확 시에는 경삽담액묘를 이용하는 것이 활착률을 향상시키고 괴경수량도 높일 수 있을 것으로 보인다.
