Flower development in rice can be divided into two big stages:. Anthesis (Flowering) There are four big steps in anthesis. SABRAO J. Breed. Genet. 49 (2) 135-143 136 for rice, normally below 20 °C and above 30 °C, vary among the different growth stages (Yoshida, 1981), with the. White back kernel and milky white rice kernel are caused by a high temperature at the ripening stage. The recent tendency of high temperature is not only.

Anthesis is the stage when rice is most sensitive to high temperature stress, understanding genetic control of the tolerance should contribute to. Anthesis is the period during which a flower is fully open and functional. It may also refer to the onset of that period. The onset of anthesis is spectacular in some.
