A high frequency plant regeneration system was established using root segments of Albizziu corenna via tissue culture. Cotyledon, hypocotyl, leaf and root explants were cultured on B5 basal medium supplemented either with TDZ(0, 0.04, 0.5, 2.3 and 4.5μM) alone or with TDZ in combination with NAA (2.7 and 5.4μM) or 2,4-D(2.3 and 4.5μM). Shoot primordia were formed when the explants were transferred to B5 medium with 0.04-4.5μM TDZ. Among the explant types tested, only root explants showed high frequency shoot regeneration. Other tissues tested did not respond well to the same culture conditions. Histological observation of the responding explants showed direct development of shoots from endodermal tissues of root segments. The shoots formed could be elongated and further grown by transferring to the medium with 1.44μM GA₃. The shoots rooted either on B5 basal medium or on B5 medium supplemented with 1.44μM GAS. Shoot regeneration potential varied among the explant types. Root explants appeared to possess the highest potentiality for in vitro shoot regeneration.

The contents of methyl trans-cinnamate, a significant and major aromatic compound in Tricholoma matsutake (pine mushroom), were determined by HPLC (High Performance Liquid Chromatography.). Mushroom sample collected from five sites in Korea were extracted with methanol by ultrasonication. The contents of methyl trans-cinnamate in the pileus and stalk of pine mushroom ranged from 84.8 to 995.7 μg/g and from 4.5 to 45.2 μg/g, respectively. The average contents of methyl trans-cinnamate in the pileus and stalk of pine mushroom from the five sites were 559.1 μg/g and 35.7 μg/g, respectively. From the results of this study, we could conclude that the contents of methly trans-cinnamate varied by different parts (pileus and stalk) and collecting sites. The amounts of methyl trans-cinnamate from tresh T. matsutake were higher than those of dried T. matsutake, Pileus of pine mushroom appeared to contain more methyl trans-cinnamate than did stalk. Additionally, as pileus of pine mushroom developed, the aroma content increased as well.
