Abstract

This paper describes the effects of the growth regulators, gibberellic acid (30 ppm) , naphtalene acetic acid (30 ppm), the biostimulants Ergostim (30 ppm) and Atonik (30 ppm) on the anatomical features of foliar and floral stalk of strawberry (Fragaria x ananassa) "Sequóia". Three weekly applications of 10 ppm were studies. They started just after plants began blooming. The leaves (lamina and petiole) and the floral stalk harvested from three plants after the last pulverization. The histological studies were carried out by preparing and observing plant material slides. Observations of the plant slides allowed us to conclude that every leaf apex and marginal serration had a terminal hydathode region. The leaf blade was amphistomatic with anomocytics stomata. There were two types of trichomes: non-glandular and glandular. On the abaxial side, there were some structures similar to a lenticel. The mesophyll was dorsiventral. The venation pattern conformed to camptodromous type. The petiole had an uniseriate epidermis with stomata and trichomes, an annular collenchyma, some parenchyma cells with druses and the collateral bundles arranged in a descontinuous cylinder. The floral stalk anatomy different to the petiole because it had a continuous perivascular fibre ring and the vascular cylinder was almost continuous. The anatomy structure of the treated plants was not affected by growth regulators.
