큰느타리버섯의 자실체 생육특성

Abstract

In this study, we investigated the properties of incubation and growing of Pleurotus eryngii in addition to the mycological properties to use them as basic data for breeding. The speed of mycelial growth on the MCM was faster than on the PDA. The biomass in the PDB broth culture was higher than in the MCM and YMG broth culture. KNR2515 and KNR2516 required 19 days for growth of mycelia on commercial sawdust media. KNR2503 required 6.5 days and 15.3 days for pin-heading and harvesting, respectively. In morphological properties by the mushroom, the heights of KNR2312 and KNR2322 were 122.7 and 121.0 mm, respectively. The thickness of KNR2322 and KNR2513 were 39.8 mm and 31.3 mm, respectively. The weight of KNR2524`s fruiting body was 36.3 g, which is good as wild strain. The quality of fruiting body of KNR2503 was 4.0 in comparison to the score 7 of commercially cultivated strains. KNR2512 had the darkest color of pileus with L value 43.6. The slow growing strains, KNR2511, KNR2513, and KNR2512 had the bright pileus with L value 80. In morphological characteristics, KNR2511, KNR2513, and KNR2515 had white lamellar and plane pileus. The three strains are supposed to be the same group and KNR2516 and KNR2518 appeared to be related to the group. The commercially cultivated strains had convex pileus, KNR2502, KNR2503, KNR2504, KNR2521, and KNR2525 had infundibuliform, and the other strains had plane pileus. Several strains were valuable for breeding, JNR2503 for growth rate, KNR2512 for pileus color, and KNR2312, KNR2322, KNR2503, and KNR2513 for the quality.
