In order to study the stem anatomy of Tahitian lime (
Citrus latifolia Tanaka), grafted on Volkameriano lemon (
Citrus volcameriano
Pasq.), samples were collected with primary, intermediate and secondary growth, at the Yaracuy state, Venezuela. These structures were sectioned and fixed in FAA for 12 hours, they were dehidrated and demersed in paraffin and mounted on block to make the cuts. These sections were dyed with saffranin and mounted in permount for their description. The stem of Tahitian lime presents unistrata epidermis, bald, with cells of thin walls. In the primary growth, the conductive tissues: xylema and primary floemas are arranged in collateral sheafs. In the intermediate growth, the conductive tissues form continuous rings. The felogen begins to produce cork (suber) towards the periphery of the stem and felodermis towards the bark, with this activity, the formation of lenticels begins in the epidermis of the stem. In the secondary growth, xilema and secondary floema are arranged in continuous rings.
