Sporulation Capacity and Longevity of <i>Puccinia horiana</i> Teliospores in Infected Chrysanthemum Leaves

Fig. 1. (A-E) Development of symptoms and pustules of the rust pathogen Puccinia horiana on the surface of an infected chrysanthemum leaf: (A) 14 DAI (days after inoculation); (B) 21 DAI; (C) 28 DAI; (D) 35 DAI; and (E) 42 DAI. Note that at 14 DAI, whitish areas have developed where pustules will later develop. By 42 DAI necrosis is apparent in the vicinity of the pustules. Pustules appear brown and not white because they have not sporulated. (F) Petri dishes set up as moist chambers for leaf assay. Note the basidiospores floating on the surface of the agar solution.
