Abstract
Leaf samples of five green coconut varieties and their F1 hybrids were collected to determine stomatal density and size. The same parameters were determined in two color forms of San Ramon. Impressions were taken on the abaxial leaf surface of the leaflets from the leaf carrying the one-year-old bunch of seednuts and were mounted for microscopic examination.
The mean number of stomates per mm2 of leaf surface ranged from 2549.0 to 4808.0. The mean length of the guard cells varied from 84.6u to 102.0u. Stomatal density and length of the green and purple San Ramon did not vary significantly. These parameters were significantly different among the green coconut varieties and their F1 hybrids. However, no distinct relationship between stomatal density or length and hybridity could be discerned.
