Gibberellins are a group of diterpenoids that are defined more by their structure than by their biological activity, contrary to what happens with Auxins and Cytokinins. Active gibberellins act as essential regulators of plant development and cover all aspects of plant life such as: seed germination, stem growth, parthenocarpy, leaf expansion, root elongation, flowering and …

Nematodes are tiny worm-like critters that live in the soil. Most of these organisms do not represent any threat to agriculture, since they feed on fungi, bacteria and other organisms. However, there are some that do represent a risk for vegetable production because they feed on their roots. Problems caused by nematodes. Nematodes manage to …
Calcium is an element that is absorbed in the form of divalent Calcium cation (Ca2+) and is abundant in the soil, however, at certain stages of crop development, plants may express symptoms of deficiency of said element. Calcium is absorbed through the tissue of “tender” roots. This is one of the main reasons for calcium …
Chlorine (Cl) is an essential element for plants, but it is required in very small quantities. Depending on the culture and its phonological stage, the Chlorine content in the tissue will be variable. Chlorine (Cl) toxicity manifests itself with burns on the margins of the leaves, premature yellowing, bronzing, even leaf drop. Among the most …
