利用神舟号飞船搭载 4个灵芝菌株 ,研究了搭载组与地面对照组不同生长时期的酯酶同工酶及菌丝体的生长速度 ,发现空间条件处理后灵芝菌丝体的酯酶同工酶及生长速度均有不同的变化。其中SX、S3分别与对照组CX、C3的酯酶同工酶在不同生长时期差异明显 ,而搭载株SH、S4与地面对照株CH、C4的酯酶同工酶差异不明显。搭载株S4比地面对照株生长快 ,而搭载株SX比地面对照株生长较慢。S3、SH与地面对照的生长速度无明显差异 Four Ganoderma lucidum strains were carried by Shenzhou spacecraft to study the growth of esterase isozymes and mycelium at different growth stages of piggyback group and ground control group. The results showed that the esterase isoenzyme And the growth rate has different changes. Among them, the esterase isoenzyme in CX and C3 of SX and S3 were significantly different at different growth stages, while the esterase isozymes of SH and S4 and ground control CH and C4 were not significantly different. Planting S4 grew faster than that of ground control, while plant growing SX grew slower than ground control. There was no significant difference in growth rate between S3 and SH and ground control
