REDUCED WINTER SURVIVAL AND YIELD OF CLOVER INFECTED WITH CLOVER YELLOW MOSAIC VIRUS

Michael J. Pratt Canadian Journal of Plant Science 1967. doi:10.4141/cjps67-051

Other claims from this paper (8)

Intervention effect In the season of infection, clover hay yield declines.
Observation In late fall, infected clover plants become stunted and show strong virus symptoms.
Intervention effect In winter, infected clover plants have lower survival than healthy plants.
Association Slow growth from virus infection, with winter injury, allows weeds and grasses to establish and spread in clover stands in spring.
Observation The infected clover plants decline in vigor as the seasonal sequence repeats.
Intervention effect In the year after infection in CYMV-infected clover plots with vigorous grasses, clover hay yield was less than one-quarter of control plots.
Intervention effect Severe strains of CYMV reduced yields of alsike, Ladino and white Dutch clovers by about half.
Observation Red clover var. Lasalle was less severely affected by CYMV than the other clovers.
