ABSTRACT Objective: To analyze the effect of open field crop management on gardenia f lower development.
Design/Methodology/Approach: A randomized block design was used with a factorial arrangement of two factors conformed by field management (four levels: M1old plant in natural shade; M2 and M3old plant in full sun and M4mature plant in full sun) and the f loral stages (eight levels: tender, lemony, striped, white, star, caracolled, open and yellow). Eight morphological descriptors were measured: f lower weight, perianth length, perianth diameter, calyx length, calyx diameter, corolla width, number of sepals, and length of sepals.
Results: The analysis of variance allowed to identify highly significant differences (P0.05) in the variables weight, perianth length, calyx length and diameter, number of sepals, and length of sepals for the management-stage interaction. In handling M1 and M2, the caracolled f lower reached a weight greater than 2.940.08 g with a perianth diameter of 60.661.23 mm. The open f lower presented the largest corolla width of 37.391.07 mm. The white button cataloged from the commercial point of view in the category of buttons, according to weight, perianth diameter, and width of the corolla, presented f lower characteristics, thus classifying the f loral development in three stages for buttons and five for f lowers.
Findings/Conclusions: Crop management with natural shade increases the size of the f lowers in terms of weight, perianth diameter, and corolla width. These descriptors can be used as quality criteria when selecting the f lower. In addition, the open and caracolled f lower can contain the largest reserve of volatile components and, as they are not commercial qualities, it could be used in the extraction of compounds to produce cosmetics.
