Thermal and mechanical shocks affecting the first flush of production of Lentinula edodes on Eucalyptus saligna logs

Abstract

The aim of this work was to evaluate the effect of thermal and mechanical shocks on the productivity of Lentinula edodes colonized on 140 Eucalyptus saligna logs at different immersion times in water and in the first flush of production. The logs were immersed in water at low temperature (16ºC) or environmental temperature (22ºC), for 6, 10, 14, 18, 22, 26 and 38 hours. The mechanical shock treatment was accomplished by dropping the logs onto the floor three consecutive times, in a vertical position. Water temperature and immersion time affected L. edodes yield, which increased two to four times when the logs were immersed in cool water for the shortest times (6 and 10 hours). The mechanical shock treatment did not increase the sporophore yield.

Sawdust and fruit residues of Central Amazonian for Panus strigellus spawn’s production

“…and Quercus acutissima Carr., were also included because Eucalyptus sp. sawdust is commonly used to cultivate edible mushrooms such as L. edodes in Southern and Southeastern Brazil (Paula et al, 2001;Queiroz et al, 2004;Silva et al, 2005;Shiomi et al, 2007;Ishikawa, 2008) and Q. acutissima is used for mushroom cultivation in Asia (Przybylowicz & Donoghue, 1990;Quimio et al, 1990).…”

Response of shock treatment on fructification of shiitake mushroom using synthetic logs of different substrates

“…The temperature shock treatments were necessary for fructification and it was verified by Tokimoto and Komatsu (1982) who reported that prolonged freezing temperature is not suitable for emerging baby shiitake mushrooms whereas, they can tolerate low temperature treatment if given in shifts. Shiomi et al (2007) also studied the effect of thermal and mechanical shocks on the first flush of production of Lentinula edodes on Eucalyptus saligna logs. They concluded that with the increase in the immersion time in water, there is decrease in the exponential behavior of sporophore fresh mass per log, number of sporophores per log, and fresh mass per sporophore on eucalyptus logs.…”
