Level of disease incidence on
trifoliolate leaves of beans (Phaseolus vulgaris) in relation to primary
infection on simple leaves infected with the same fungus, by J.N.
Zulu and B.E.J. Wheeler, Vol.6, no.1, Zambia Journal of Science and Technology,
March 1981, Pg. 14-19.
Experiments with plants of Phaseolus vulgaris L (cultivar 'Prince') showed that
first trifolialate leaves inoculated with rust (Uromyces Phaseoli Arth.)
developed significantly fewer pustule numbers, if the same plants' simple leaves
were infected with the same rust disease. However, experiments with cultivar
'Pinto', a more susceptible cultivar did not show this association. Inoculating
the simple leaves of cv. 'Prince' with a higher concentration of the inoculum
did not increase the resistance of the first trifoliolate leaves. Similarly,
inoculating the simple leaves of 'Prince' with a non-compatible rust (Uromyces
viciae-fabae (Pers.) De Bary) did not induce resistance to U. phaseoli in the
first trifoliolate leaves.
