Abstract

Polyploidy is a common phenomenon in plants, especially on the species of ferns. The objectives of this research are to find out the variation of the ploidy levels, to know the effects on the stomata index and size of stomata and spore in Adiantum raddianum. The materials used to conduct this observation of chromosomes number were made from root tips or young leaf tips (croziers). The modified squash method was used in microscopic preparation. The result of the observation showed that there was a variation in ploidy levels from 2n = 2x (diploid) to 2n = 7x (septaploid). It appeared to be general trend that the higher level the ploidy causes the lower the index stomata but the bigger the stomata and the spore size.
