Morphological and productivity comparison between commercial and wild isolates of Pleurotus eryngii (D.C.: Fr.) QuÃ©l
Seven commercial isolates of Pleurotus eryngii (â€˜142 Fâ€™, â€˜142 Eâ€™, â€˜D +â€™, â€˜V turboâ€™, â€˜V 142â€™, â€˜A12â€™ and â€˜V160â€™), identified on molecular basis, were compared to five wild type isolates (â€˜Albino beige chiaro 1094â€™, â€˜Altamura 1603â€™, â€˜Albino 1107â€™, â€˜Muro Lucano 139â€™ and â€˜Conversano 1250â€™) concerning their morphological, productivity and quality features. Interestingly, two wild type isolates (â€˜Albino 1107â€™ and â€˜Conversano 1250â€™) resulted more productive then all the commercial fungal isolates analysed. Besides, all wild isolates of P. eryngii showed harvest earliness and among them â€˜Altamura 1603â€™ and â€˜Conversano 1250â€™ were the best. The highest percentage of large basidioma was observed for the commercial isolates â€˜V turboâ€™ and â€˜D+â€™. Within the wild types, the isolate â€˜Conversano 1250â€™ stood out. Regarding the pileus cuticle colour, commercial isolates (â€˜V turboâ€™ and â€˜V 160â€™) showed lower lightness value than wild type isolates (â€˜Albino 1107â€™).
