Table 2: Pigment concentration of chlorophyll a, chlorophyll b, carotenoids and anthocyanins measured at four developmental stages in inflorescence bract of 'Red' and 'Yellow' cultivars of C.
The maximum SY of cultivar pa was due to high chlorophyll a, chlorophyll b, and chlorophyll ab and stomatal Conductance.
Previous studies using portable equipment with such plants as cotton and coffee demonstrated the possibility of indirectly determining the chlorophyll b content (NEVES et al.
The content ratio of chlorophyll a to chlorophyll b (Ca/Cb) at the same growth period maintained at about 3 both in Burley21 and Maryland609 from transplanting period to mature period; the content ratio of total chlorophyll to carotenoid (Ca + b/Cx) in Maryland609 also maintained at about 5, but in Burley21, it showed a downward trend (Table 2).
Most plants possess chlorophyll a and chlorophyll b which are the main photosynthetic pigments (Campbell and Reece,2005).
The relationship between the chlorophyll readings from both portable meters and the contents of chlorophyll a and chlorophyll b was more readily expressed with a quadratic model.
Changes in chlorophyll a/b ratios were always caused by changes in chlorophyll b.
As one explanation for the pigment similarity, the researchers suggest that both chloroplasts and Prochlorothrix could have separately evolved chlorophyll b.
spurca significantly increased leaf chlorophyll a, chlorophyll b, carotenoid, and total chlorophyll contents irrespectively of citrus genotype, whereas the increases of chlorophyll contents induced by D.
