Potato Root Diffusate Production

Potato Root Diffusate Production POTATO ROOT DIFFUSATE PRODUCTION BY ELIZABETH WIDDOWSON Rothamsted Experimental Station, Harpenden, Herts., England. Pot tests were made to assess the effects of plant age, variety, and an infestation of potato-root eelworm, Heterodera rostochiensis Woll., on the activity of root diffusate produced by potted potatoes; the dif- fusates produced by one variety of potato and one variety of tomato were also compared. Technique The same methods for growing the plants, leaching out, and assaying the diffusates, were followed in all the pot tests. Chitted tubers of the variety Arran Banner were used throughout. Each was approximately 2 oz. in weight and all the shoots but one were cut out of each tuber before they were planted in coarse horticultural sand in diame- ter pots. The plants were fed with a nutrient solution, twice weekly and grown in a cool glasshouse during the early summer. The leaching was started when the potato shoots were just showing through the sand, at "breakthrough", this was usually about two weeks after planting.
