Chlorophylls (a and b) and carotenoid were recorded at 663, 645,
and 470 nm, respectively. As tomato seedlings were treated with
bacterial suspension and chlorophyll contents were recorded after
three weeks of the treatment. The chlorophyll contents were
significantly enhanced by the application of MPB 2.1 culture after 9th
d. By comparing the results chlorophyll a contents showed an increase
of 0.4 mg/g while 0.34 mg/g in chlorophyll b contents were recorded.
In this way, the total carotenoid presented the pragmatic results with
comparison to control (Fig. 5c).
