2. ESTIMATION OF CHLOROPHYLL “A” AND “B” OF SOME AQUATIC PLANTS by J.N. PATEL AND N.K. PATEL
Chlorophyll a, b, c, d, carotene, xanthophylls are present in all higher plants. Then chlorophyll a and b are most important for plants. Make extract of chlorophyll in 80% acetone and estimate by spectrophotometer in Optical Density. Chlorophyll a and b are measured in amount of gm/lt. Chlorophyll was estimate of hydrophytes plants in Eichornia crassipes (mart) Solms, Hydrilla verticilata (L.F.) Royal, Nelumbo nucifera Gaerm and Trapa bispinosa Robe. The range of chlorophyll contains are 0.0003571 to 0.009084 gm/lt for chlorophyll a and 0.001191 to 0.007670 gm/lt for chlorophyll b.
