MENCHACA-CEJA, Felipe et al. Relationship of naphthaleneacetic acid in quality components of Muskmelon Cantaloupe melon (Cucumis melo L.). Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.14, pp.171-179. ISSN 2007-901X.  https://doi.org/10.19136/era.a5n14.1397.

The aim was to determine the influence of naphthaleneacetic acid on the quality and yield components of 'Navigator' and 'Thunderbird' muskmelons. The experiment was carried out in the experimental field of the Institute of Agricultural Sciences of the Autonomous University of Baja California. Three treatments of naphthaleneacetic acid (0.1, 0.2 and 0.4 mg L-1) plus a control (0.0 mg L-1) were evaluated in a completely randomized design with four repetitions; the study variables were weight, equatorial length, polar length, concentration of total soluble solids (TSS), pulp firmness, pulp color and aromatic compounds. The results show that the three naphthaleneacetic acid treatments induced greater firmness and TSS content in 'Navigator' muskmelon fruits, while for 'Thunderbird' these treatments induced less firmness and TSS content. The naphthaleneacetic acid treatments increased the concentration of ethyl propionate and butyl acetate in 'Navigator'; for 'Thunderbird', the treatments were associated with a higher concentration of ethyl isobutyrate and ethyl acetate. The three naphthaleneacetic acid treatments had no significant effect on weight and equatorial and polar length compared to the control. Naphthaleneacetic acid influenced the quality parameters of the fruits but did have significant effects on the yield components.
