Effect Of Different Sugars On Radial Growth And Dry Matter Weight Of Milky Mushroom (Calocybe Indica)

Milky mushroom a popular mushroom was first time reported from India in 1976. It can be easily grown in temp. range of 25–350C with 75 -85% relative humidity, therefore with respect to study was undertaken to assess the beneficial effect of different sugars viz: Glucose, Maltose, Fructose and Sucrose on the radial growth (cm) of different five strains of Calocybe indica i.e. CI-5, CI-10, CI-14 CI-15, and for dry matter weight (mg/50ml) three strain APK-2, CI-14 and CI-15 was observed. The experim?ent was conducted session 2013- 2014 in Laboratory of Department of Plant Pathology, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh (250110) in completely randomized design with four treatment and control (no added sugar in medium) with three replications. The observations of radial growth (cm) were taken at each 48 hrs till the colony covered the first full plate. It is evident from the data presented in table that different sugar solutions viz. glucose(1%), fructose(1%), maltose(1%) and sucrose (1%) significantly increased the radial growth of the strains of C. indica (i.e. CI-5, CI-10, CI-14, CI-15 and APK-2) as compared to control. These results revealed that among the sugars solutions tested, at 8th days of observation in glucose solution the radial growth of strain CI-14 was found maximum (full growth) diametric growth of mycelium (9.00 cm). The minimum growth was observed of strains CI-5 (5.23 cm) in fructose as compared to control respectively. For the dry matter (mycelial) weight, maximum weight was found in fructose (1.82 mg) from strain APK-2 and in case of strain CI-14 (1.48 mg) in glucose and in CI-15 (1.63 mg) in maltose which are significantly superior control. In same way minimum dry matter growth (1.12, 1.16 & 1.23 mg) from all the three strain was found in control followed by fructose (1.24 mg & 1.30 mg) from strain CI-14 and CI-15 respectively.
