Water deficit causes interferences in the biochemical activities, production of photosynthetic materials, and shortage of seed capacity, chlorophyll a, chlorophyll b, total chlorophyll and stomatal conductance causes a decrease in seed yield.

The relationship between the chlorophyll a and the chlorophyll b is described in Figure 5.
Based on our mathematical models, with the exception of chlorophyll b, the ClorofiLOG[R] 1030 portable chlorophyll meter estimated the concentration of photosynthetic pigments with high precision, thus saving time and the chemical reagents that are typically used in conventional procedures.
The normal content ratio of chlorophyll a to chlorophyll b is about 3: 1 (Jeffrey, 1961; He et al.
These results indicated that the yellow-green leaf color of burley tobacco was not the result of imbalance in content ratio between chlorophyll a and chlorophyll b, but the abnormal lower content of total chlorophyll in its leaves.
The chlorophyll concentration was calculated using specific absorption coefficients for total chlorophyll, chlorophyll a and chlorophyll b provided by the following:Total chlorophyll = 20.
Total chlorophyll, chlorophyll a, chlorophyll b and chlorophyll a/b ratios of both legumes were significantly affected by fertilizer application over time.
Chlorophyll a is more strongly degraded than chlorophyll b
(WOLF, 1956), which may explain the reduction of the chlorophyll a/b ratio when the chlorophyll meter readings were below 40 (Figure 2b).
