First Report of Zucchini yellow mosaic virus on Hollyhock (Althaea rosea)

Study of resistance to cucumber mosaic virus watermelon mosaic virus and zucchini yellow mosaic virus in melon cultivars

Copper Effects on Growth Parameters of Hollyhock (Althaea rosea L.)

Copper is an essential micronutrient for plant growth which is involved in many metabolic processes. However excessive amounts of copper may cause environmental pollution. With an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. The effects of heavy metals on the growth parameter...

Inheritance of resistance to zucchini yellow mosaic virus and watermelon mosaic virus in watermelon.

High resistance to zucchini yellow mosaic virus-China strain (ZYMV-CH) and moderate resistance to watermelon mosaic virus (WMV) were found in a selection of PI 595203 (Citrullus lanatus var. lanatus), an Egusi type originally collected in Nigeria. Mixed inoculations showed primarily that these two viruses have no cross-protection. This fact may explain the high frequency of mixed infection ofte...
