The "Research Paper" Debate
    #20904159 - 11/29/14 11:44 AM (9 years, 3 months ago)

Many people here enjoy the science behind mushrooms and being/doing the best at everything. So, I have started the "Research Paper" Debate to help entertain the science culture in the community. This thread is here to post research papers on mushrooms and why we think this info is valuable.


---------

I will start. I believe that slower growing spawn and fruits will lead to bigger/dense mushrooms in both oysters and cubes. (note, look at the tables in the research paper link. You will enjoy it if you like numbers and detailed statistics)


Quote:

Generally speaking, increasing the amount of cotton seed hull in the substrate mixture slowed spawn running, primordial development and fruit body formation. However, increasing amount of cotton seed hull increased the uniformity and white of mycelium, yield and BE, and increase mushroom weight, enlarged cap diameter and shorten stipe length of oyster mushroom (Tables 2–4).

Here is the link to the research paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3824138/

Lower temps are already linked with denser fruit bu this is a good thread :thumbup:

Also read somewhere you can electrocute your sub but RR said it only gets you a 7-9% BE increase. Not worth the trouble.

I'll be watching though,

I like the research papers because the amount of statistical data that can be applied to future exploration of growing mushrooms.


----
Look at the data on this research paper. The data shows that the media used for the spawn has a HUGE impact on the final BE.

Quote:

White maize (Bende Local) was found to be most favourable to mycelial extension and mycelial fresh weight of P. tuber regium and P. pulmonarius. The result of the analysis of variance (Table 1 and 2) showed that the mean mycelial fresh weight were 3.767±0.030 cm and 1.583±0.0099, respectively for P. tuber-regium on the 6th day of incubation. In the case of P. pulmonarius, the mean mycelial extension and mean myucelial fresh weight were 3.622±0.032 cm and 1.137±0.008 g. Red sorghum was next to white maize with mean value for mycelial extension and mycelial fresh weight were 2.311±0.032 cm and 0.922±0.008 g. All the substrates supported the growth of mycelia of the two pleurotus species studied but in varying degrees. The least support for both species studied was shown by wheat (Table 1 and 2).

In all substrates P. tuber-regium did better than P. pulmonarius in terms of mean mycelial extension and mean mycelial fresh weight except on red sorghum whee P. pulmonarius was better.

Tinoco et al. (2001) found that larger surface are a and pore of substrates support more mycelium growth rate. This could account for the result recorded by white maize (bende Local). It is a floury maize grain whose grains were larger than other substrates used in this study.

RR was talking about logs vs bags. bags can give you >100% BE but fruting off of logs inoculated with plugs gives you 7-9%BE which is why they were testing the effects of electrocution/lightning. but the results are largely inconclusive

Bags can give me over 100 percent BE?

200-300% or so.

look up what BE is, it will make more sense.

dry weight of substrate to wet weight of mushrooms.

Biological Efficiency,
I get it, just didn't know it was that big of a boom.

i never heard of 200-300% that often, thats crazy!!  gimme that strain!

maybe that's a little high I just wrote from memory. 150% is easily achievable though

Guys, show me the research or at least a thread when making statements.
