Naturevolume 180page816 (1957) | Download Citation



THERE is a difference of opinion regarding the presence or absence of florigenic properties of the plant-growth substances. The flowering behaviour of various crop plants as influenced by these substances has been studied by many workers in the field1–5. The present investigation aims at studying the effect of various plant-growth substances such as β-indolylacetie acid, α-naphthylacetic acid and 2,3,5-triiodobenzoic asid on the flowering of four different varieties6 of rice.
