Stomatal length and frequency as a measure of ploidy level in black wattle, Acacia mearnsii (de Wild)
The length and frequency of stomata on leaf surfaces were examined as rapid techniques for future identification of ploidy level of Acacia mearnsii (de Wild). Diploid (2n = 2x = 26) and tetraploid (2n = 4x = 52) plants were germinated from chipped seed at 25°C and grown under nursery conditions. Aft...
