Re-supplementing and re-casing mushroom (Agaricus bisporus) compost for a second crop

 Rodriguez Estrada AE, Jimenez-Gasco Mdel M, Royse DJ.

Experiments were performed to determine the effect of adding nutrient supplements to colonized mushroom compost (MC) for the production of a second crop of mushrooms. Mushrooms were harvested for 1, 2 or 3 flushes, the casing removed and the MC then was fragmented and re-supplemented with delayed release supplements treated or non-treated with fungicide (thiophanate-methyl; Topsin M 70WP) and re-cased. Overall double-crop yields were higher when MC was re-supplemented after 1st flush (1st flush MC) as compared to re-supplementation after the 2nd or 3rd flushes. Mean double-crop BEs were 128, 119 and 109% when 1st-, 2nd- and 3rd-flush MCs were used, respectively. Treatment of delayed release supplement with thiophanate-methyl fungicide did not affect mushroom yields. Soluble salts and potassium concentrations increased 350 and 900%, respectively, in the casing overlay through three flushes suggesting that removal of the casing would help to alleviate the build up of these potential growth-limiting materials. Re-supplementing and re-casing of MC represents a potential opportunity for growers to increase revenues and reduce costs associated with preparation and disposal of compost. The ability to double-crop mushroom compost would provide growers a chance to increase yields by 40% or more, depending on whether they re-supplement and re-case after 1st, 2nd or 3rd flush.

Genetic Diversity of the Edible Mushroom Pleurotus sp. by Amplified Fragment Length Polymorphism

Abstract

Pleurotus strains are the most important fungi used in the agricultural industry. The exact characterization and identification of Pleurotus species is fundamental for correct identification of the individuals and exploiting their full potential in food industry. The amplified fragment length polymorphism (AFLP) method was applied for genomic fingerprinting of 21 Pleurotus isolates of Asian and European origin. Using one PstI restriction endonuclease and four selective primers in an AFLP assay, 371 DNA fragments were generated, including 308 polymorphic bands. The AFLP profiles were found to be highly specific for each strain and they unambiguously distinguished 21 Pleurotus sp. fungi. The coefficient of Jaccard’s genome profile similarity between the analyzed strains ranged from 0.0 (Pleurotus sp. I vs. P. sajor-caju 237 and P. eryngii 238) to 0.750 (P. ostreatus 246 vs. P. ostreatus 248), and the average was 0.378. The AFLP-based dendrogram generated by the UPGMA method grouped all the Pleurotus fungi studied into two major clusters and one independent lineage located on the outskirt of the tree occupied by naturally growing Pleurotus species strain I. The results of the present study suggest the possible applicability of the AFLP-PstI method in effective identification and molecular characterization of Pleurotus sp. strains.

سلام آقای دکتر وقتتون بخیر در تابلو اعلاناتتون نوشتید کنترل مگس سفید در سالنهای قارچ صدفی؟میخواستم روش کنترلتون رو بدونم چون منطقه ما این مشکل رو در گلخانه ها دارد  و کنترل صدردصدی تا حالا نداشتیم. اگر شما روشی دارین کاملا افت رو ریشه کن می کنید ممنون میشم اگر به ما هم ارایه کنید.
