Abstract
The cytological effects of water extracts prepared from Arisaema japonicum and Chelidonium majus have been studied with root tip cells of Trillium kamtschaticum and ovular tissue cells of Paris tetraphylla.
Arisaema extracts were prepared by immersing 25 grams of roots and bulbs into 100cc of tap water. Remarkable effects of extracts after treatments for 4.5 and 7.5 hours are stickiness of chromosomes at metaphase and sticky bridges at anaphase or telophase. In addition to these anormalies, the occurrences of pseudochiasmata at anaphase and of lanky chromosomes at metaphase were recorded. Chelidonium extracts were prepared by immersing 25 grams of the whole plant into 100cc of tap water. Cells treated with extracts for 4.5 and 7.5 hours showed the stickiness and clotting of chromosomes.
