In this case, it has two effects on chlorophyll b
fluorescence (peaks at 640 and 667 nm).
For 'Maravilha', the correlations with high magnitude, positive and more significant (p < 0.05) occurred between the leaf contents of N and Mg and the index of chlorophyll b
(0.96 and 0.95, respectively), between S contents and total chlorophyll (0.91) and between the contents of B and Zn and the index of chlorophyll a (0.91 and 0.92, respectively) (Table 5).
Characteristics, namely, height, GBH, chlorofluorescence, chlorophyll a, chlorophyll b
, total chlorophyll, chlorophyll ratio, protein, and sugar exhibited significantly both positive and negative correlation.
There are 2 type of chlorophyll pigments being study in this analysis; chlorophyll a and chlorophyll b
. Chlorophyll a was the main pigment that assists the photosynthesis reaction while chlorophyll b
was the accessory pigments that function to passes energy absorbed through the visible wavelength to chlorophyll a for the photosynthesis process.
Both, concentration of chlorophyll a and chlorophyll b
were increased in partially coloured bracts.
Most plants possess chlorophyll a and chlorophyll b
which are the main photosynthetic pigments (Campbell and Reece,2005).
At flowering time, 20 plants were chosen randomly from each plot to determine yield attributes including chlorophyll a, chlorophyll b
(by spectrometer), chlorophyll ab, total chlorophyll (by chlorophyll measurement), and yield per hectare and stomatal Conductance.
The leaf chlorophyll a concentration appeared to be reduced to a greater proportion than chlorophyll b
concentration in these greenbug-damaged leaves (Table 1).
As one explanation for the pigment similarity, the researchers suggest that both chloroplasts and Prochlorothrix could have separately evolved chlorophyll b
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).
