Abstract The influences of high temperature and fertilization with biochar and phosphorus (P) on the pollen characteristics of two rice cultivars (IR-64 and Huanghuazhan) were examined in controlled growth chambers. Temperature treatments included high daytime temperature (HDT), high nighttime temperature (HNT) and ambient temperature (AT). The fertilization treatments were control, biochar alone, P alone and biochar + P. High temperature severely reduced pollen fertility, anther dehiscence, pollen retention and pollen germination of both rice cultivars, with HNT more destructive than HDT. The Huanghuazhan cultivar performed better than IR-64 under high temperature, with higher pollen fertility, better anther dehiscence and greater pollen retention and germination rates. In both cultivars, the pollen of plants treated with biochar + P were more resistant to heat induced stress. Further studies are needed to test the ability of biochar to ameliorate the effects of different abiotic stresses in rice and other crops.
