Abstract
SummaryExperiments were conducted during 1993 and 1994 at Bangalore, India, to estimate the reductions in yield of essential oil caused by leaf blight (Colletotrichum gloeosporioides (Penz.) Sacc.) on three geranium (Pelargonium graveolens (L.) Herit) clones. Leaf blight resulted in smaller reductions in oil yield in an Algerian-type (Kd) clone than a Reunion-type (Lo) and an Egyptian-type (Eg) clone. The results indicate that even expensive disease management practices can be recommended for management of leaf blight on the Lo and Eg clones in regions where leaf blight is prevalent, because increases in severity of leaf blight may cause considerable economic loss. Such measures, however, may not be economically viable for the Kd clone.
期刊介绍：
The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
