    Effect of low temperature on fruiting body formation in Pleurotus sajor-caju
    (2007-02-08) Moorthy, V.K.; Chandra Mohanan, R.
    Pleurotus sajor-caju (Ft.) Singer, was grown in three different temperature ranges viz., 17.0 to 25.0°C, 20.5 to 27,0°C, and 23.5 to 28.0°C using two substrates - paddy straw and paddy straw + arecanut leaf sheath (1:1 W/W). At the end of spawn run and subsequently at the end of each harvest air temperature was suddenly reduced by 2 - 3°C and maintained at this temperature for two days and again brought back to the original temperature. The sudden fall in temperature induced budding in the mushroom bags and peak harvest was obtained within 3-4 days from the day of low temperature treatment. Peak harvest was also achieved in mushroom bags of different age almost on the same day when they were subjected to low temperature treatment.

    Seasonal variation in contamination of spawn and yield of Pleurotus sajor-caju (Fr.) Singer in a commercial farm in coastal Karnataka
    (1996) Moorthy, V.K.; Chandra Mohanan, R.
    Observation on contamination of Pleurotus sajor-caju spawn bottles in a commercial farm in Dakshina Kannada district of Karnataka in different seasons for two years revealed that contamination was the highest during monsoon season, followed by post-monsoon season. But the over-all success of spawn production was high (91.4%) in the commercial farm. The contamination of spawned bags was also highest during monsoon season. In spite of higher contamination, the yield was highest during monsoon season in all the three years of observation and lowest during pre-monsoon period. However, the yield of P. sajor-caju, obtained in the commercial farm was not very good.
