title: Effect of sudden fluctuations of temperature on sporulation of Puccinia graminis f.sp. tritici.
abstract: Six races of Puccinia graminis f.sp. tritici were grown on detached leaves of Agra Local wheat and RS 6 barley. On both hosts each race grew and sporulated better when kept at one set of temperature conditions (25 degrees C for 24 hrs + 15 degrees C for 48 hrs + 20 degrees C for 20 days) than at another (25 degrees C for 24 hrs + 15 degrees C for 20 days).
