Several antibiotic compounds have been isolated from green plants. Those which have been structurally identified, are citrinin (l-4), dicumarol (5-7), and protoanemonin (8, 9). Other less well defined factors are an oil from AZZium sativum (lo-12), a colorless crystalline compound from Arci&rz minus (13), Products A and B from Asarum cunadense (14), cassic acid from the leaves of Custiu reticdu...

Since its emergence in Northwest Europe as a pathogen that infects trunks and branches of Aesculus spp. (the horse chestnuts) approximately one decade ago, Pseudomonas syringae pv. aesculi has rapidly established itself as major threat to these trees. Infected trees exhibit extensive necrosis of phloem and cambium, which can ultimately lead to dieback. The events after host entry leading to ext...

The native peels of two cheap, locally available adsorbents, watermelon (PWM) and water chestnuts (PWC), were chemically processed with different chemicals as modifying agents for the determination assessment their adsorption ability removal clearance harmful, venomous, pernicious Congo red (CGR), an acidic nature anionic dye, from aqueous system. In successive batch experiments, citric acid-tr...

Sprouts and stumps of American chestnut, Castanea dentata [Marsh.] Borkh., were mapped from data collected at three forested sites of varying size and historical background in Cuyahoga County of northeast Ohio to compare the species' present distribution with that of its historical distribution in the mentioned areas. Sprouts were absent from one site despite a dense population of remnant chest...
