Abstract

|
|
Studies were made to investigate the difference of the shiitake productivity according to the use of sawdust and liquid spawn on middle-temperature type strain. Treatments inoculated with sawdust spawn have shown that yields were dispersed according to flushing periods and fruit-bodies occurred sporadically on medium. However, treatments inoculated with liquid spawn have shown that yield was relatively concentrated at 1st flushing period and fruit-bodies were densely occurred on medium. At total yield and the number of fresh fruit-bodies until seventh flushing, treatments inoculated with liquid spawn were more than those inoculated with sawdust spawn. Also, biological efficiency (B.E.) of inoculation with 20 ml liquid spawn which produced 30% of the medium weight was highest as 69%, but biological efficiency of inoculation with 10 g sawdust spawn was lowest as 42%. And, although rate of fruit-bodies over 10 g in total yield was high on treatments inoculated with sawdust spawn, amounts of fruit-bodies over 10 g were not different among treatments.
