Jerusalem artichoke, effect

Tables IV and VII give the percentage of the final frond number noted compared to the control for the same fractions as given in Tables I and II. The magnitude of the response in all cases is proportional to that noted on the basis of dried weight of fronds. The difference, where present, may be due to the size of the fronds since the effect of the phytochemical may be to limit frond size but not necessarily the number of fronds. Tables V, VI, and VIII give a description of the visual appearance of the fronds treated. Tables V and VI give the observations after 5 and 7 days, respectively, for the fraction from the sunflower, and Table VIII, for those from Jerusalem artichoke after 7 days.

Relating the effects caused by specific allelochemicals to those caused by an allelopathic plant is complicated because the inhibitory substances released from a plant are often unknown, and generally several different compounds are involved. However, the actions of the weeds studied in our investigations have certain parallels to those found from pCA and FA. The allelopathic nature of Kochi a, Jerusalem artichoke, and cocklebur was established, since both aque-ous extracts and weed residues reduced sorghum growth. The data show a concentration dependency characteristic of allelopathy, and some difference in toxicity among the three weeds was observed with cockle-bur the most toxic.

Jerusalem artichoke has beneficial effects on digestion. It is a good source of dietary fiber, for instance, which helps to bulk food and reduce constipation. However, there can be digestive downsides too. 

Harold McGee (1992) has outlined culinary procedures to tone down the undesirable side effects of Jerusalem artichoke. These procedures either remove some of the inulin from the tubers...
