| Abstract |
Seasonal variations in photosynthesis of cassava cv. Rayong 9 (RY9) under irrigated and rain-fed conditions were
evaluated at the age of three and six months after planting (MAP). Photosynthetic light-response (PN/I) curves revealed
that cassava leaves attained the highest maximum net photosynthetic rates (PNmax) in the rainy season, followed by the hot
one, while the lowest PNmax was found in the cool season. Photosynthetic potential of the 3-month-old plants was mostly
higher than that of the 6-month-old plants, and the seasonal variation in photosynthetic capacity was also more apparent
in the younger plants. PN/I curves were used to predict daily net photosynthetic rate (PN) for each season based on daily
average solar radiation data. The predicted PN were considerably lower than the PNmax values. This indicated that solar
radiation is a limiting factor for photosynthesis, particularly in the rainy season. The data provided basic information for
breeding cassava genotypes with enhanced photosynthesis during the period of unfavorable environment. Furthermore,
the data are potentially useful in modeling photosynthesis and crop growth as affected by environmental factors. |
