Abstract
This study was conducted to determine the effects of temperature (T) and light intensity (L) on spawn run period
(SRP), days to first harvest (DFH) and mushroom yield (MY) of different Pleurotus species grown under an
unheated high plastic tunnel in the Black Sea region of Turkey during the period of autumn and winter seasons. In
this study, three disinfection methods (D) (autoclave, formaldehyde 1% and 3%), three substrate weights (1, 2 and
3 kg) and three Pleurotus species (P. ostreatus, P. sajor-caju, P. sapidus) were used. In this study, regression
models were developed to estimate of spawn run period (SRP = 466.14 – 40.56 × T + 0.93 × T^2), days to first
harvest(DFH = 286 610.7 – 46 643.4 × T – 40 868.5 × D + 1 897.835 × T^2 + 6657.039 × T × D – 270.99 × T^2 ×D)
and mushroom yield (MY = 137.223 – 23.221 × D – 0.425 × T^2 + 0.0424 × L × D – 0.0608 × L × S + 0.048 × T^2 ×
D + 11.854 × S). Spawn run period, days to first harvest and mushroom yield were able to estimate with probability
of 98%, 81% and 82%, respectively, using developed regression models.
