抄録
Seedlings of eggplant, cv.‘Kokuyou’and sweet pepper, cv.‘Shinsakigakemidori’were grown in three different media (soil; 1 soil: 1 bark compost; bark compost) at two fertilizer application levels 40N: 80P: 40K kg/10a and 20N: 40P: 20K kg/10a) for 50 days and then these were transplanted to a vinyl house.<BR>1) Seedlings grown with the high level of fertilizer application showed vigorous growth and a higher stem weight/root weight (S/R) value than those grown with the low level.<BR>2) The higher yield was obtained on the plants from the seedlings grown in soil and those grown in 1 soil: 1 bark compost, both treated with the low level of fertilizer application, which grew faster, developed a deeper and wider root system consisting mainly in thick roots over 1 mm in diameter both in eggplant and sweet pepper. The lowest yield was obtained on the plants from the seedlings which grown in bark compost with the same low level of fertilizer application.<BR>3) The yield was closely correlated to the number of thick roots over 1 mm in diameter. The more the number of thick roots, the higher the yield.<BR>4) Plants with the lower S/R value at transplanting time developed better and showed a higher yield. There was also a correlation between the yield and S/R value.<BR>5) It may be concluded that S/R value is useful as an index for judging the quality of seedling.
