Ultrastructural Studies On The Cultivation Processes And Growth And Development Of The Cultivated Mushroom Agaricus Bisporus, D. A. Wood, G. D. Craig, P. T. Atkey, R. J. Newsam, K. Gull

Food Structure

Scanning electron microscopy (SEM) , transmission electron microscopy and light microscopy have been used to study various processes in the cultivation of the edible mushroom Agaricus bisporus . Mushrooms are cultured on composted wheat straw. The microbial degradation processes during composting have been visualised by TEM and SEM and correlated with microbiological studies . Various modes of attack by the microorganisms on the plant cell walls can be seen. Most rapid degradation occurred on the cuticle and phloem and spread to other cell types. Microbial attack was found to be nonuniform between tissue types and individual cells. The mycelium of …

Soil Hardpans And Plant Growth, J W. Bowden, R. J. Jarvis

Journal of the Department of Agriculture, Western Australia, Series 4

When farm vehicles travel over moist soils they can create hardpans which can marledly reduce crop and pasture yields.

Research at Wongan Hills Research Station has shown that plant growth and nutrient uptake were affected for at least eight years after the original workings caused the hardpan.
