Rice cultivars (Oryza sativa L.) that are adapted to high altitude areas of the sub-tropics, such as Nepal have to germinate and rapidly synthesize chlorophyll in the emerging plumule at chilling temperatures. This study was conducted to determine, at the chilling temperature or 17 degrees C the her...
