Abstract

The green pigments and their absorption of king grass (Pennisetum purpureum) mutants obtained by the application of nuclear techniques (CUBA MF 1000, 12, 18, 24, 30, 40 and 50) and chemical mutagens (CUBA MQ 1and 2) were studied in a random block design with 4 replications. There were no differences between mutants for the chlorophyll a contents in the dry period but the rainy period the CUBA MF 12, 18,30 and 50 (3.77, 3.56, 3.44 and 3.66 mg/dm(2), respectively) surpassed (P < 0.01) the king grass (2.72 mg/dm(2)). Then were no differences between mutants for the chlorophyll b contents in the dry period and in the rainy period, with the exception of the CUBA MF 24, 40, CUBA MQ 1 and 2, the rest surpassed (P < 0.01) the king grass (1.08 mg/dm(2). The carotenoid contents showed differences between mutants and values ranged between 1.69 and 2.13 mg/dm(2) in the dry period, and from 0.43 to 0.68 in the rainy period. All plants showed the highest light absorption at 420and 660 nm varying with the amplitude and intensity. The variation and the importance of the indicators studied as well as their usefulnessto determine variability between mutants is discussed.
