Resumen
Descripción
Flavonoids, the pharmaco-active compounds studied in this work, in general, are located inthe shoots as natural pigments that protect the plants from damage by oxidizing agents. The experimentwas conducted in the greenhouse of the Fitotecnia Department, Federal University of Viçosa, Minas GeraisStaty. The experimental design was completely randomized with five treatments and five replications. Thetreatments were the time of harvest: zero, three, six, nine, and twelve days after anthesis (DAA). The heightof the plant (mm), stem diameter (mm), number of leaves and total flavonoid content (%, w w-1) weredetermined. We developed growth curves for calendula with growth behavior assessed through time forheight, stem diameter and number of leaves. The time of the harvest season positively influenced the totalflavonoid contents and the average productivity of flowers, and the highest content of flavonoids was foundthree DAA. The average productivity of the flowers and the accumulation of flavonoids wereheterogeneous among harvest times (0, 3, 6, 9 and 12 days after anthesis). The highest yield of flavonoidswas obtained three days after anthesis; therefore, a harvest of the inflorescences is recommended everythree days.
