Environmental control of flowering in tropical ‐ subtropical grasses

Abstract

Tropical‐subtropical grasses have shown a wide range of response to photoperiod. Some of the response patterns which they exhibit are extremely complex and often seem unrelated to the conditions to which the plants are adapted. However, there is an increasing realization of the possible role of factors of the environment other than photoperiod in controlling the flowering process.

UITTREKSEL

Tropiese en sub‐tropiese grassoorte het wyd uiteenlopende reaksies t.o.v. fotoperiode getoon. Sommige reaksie‐patrone is utters ingewikkeld en skynbaar dikwels uit verband met die omgewingstoestande waarby hulle aange‐pas is. Daar is egter ‘n toenemende besef van die moontlike rol wat omgewingsfaktore, anders as fotoperiode, in die beheer van die blomproses speel.
