FIG. 1 shows how the HTMB application in pepper plants causes simultaneous increase in ethylene and putrescine. This effect was directly related to increases in the number of fruits and in fruit coloration (more advanced maturation state) (FIG. 2).
FIG. 1 shows the effect of HMTB according to the formulation of Example 1 on ethylene and putrescine production in pepper leaves treated on the leaves. Measurements were performed 7 days after applying the product. HMTB D1 is 100 mg/l of solution and D2 is 1 g/l of solution.
FIG. 2 shows the effect of leaf application of HMTB according to the formulation of Example 1 on the number of fruits per plant in a pepper culture. Measurements were taken 45 days after applying the product. HMTB D1 is 100 mg/l of solution and D2 is 1 g/l of solution.
Formulations containing HMTB can be applied by root and leaf route, although the most notable effect on maturation is via leaf route at fruit veraison (when the fruit starts to change color).
Recommended doses are between 1 and 5 g per liter of active ingredient, although significant effects have been recorded at lower doses such as 100 mg per liter, for example.
