Cambium is a thin region of actively dividing cells between the inner bark and the wood of a woody stem. During mango grafting, close alignment of living cambial regions helps the scion and rootstock form a functioning connection. Matching outer bark alone may not provide that contact when stems differ in thickness. Clean cuts, secure wrapping, and protection from movement support healing; pushing two cut surfaces together does not guarantee that their living tissues are correctly aligned.
A chelate is a compound in which a metal ion is held by an organic molecule. Certain chelated nutrient products help keep elements such as iron available under conditions where they would otherwise become less soluble. The chelating agent and soil pH matter, so products are not interchangeable simply because their labels say chelated. For a mango with suspected nutrient deficiency, consider root health and test information first; a chelate does not correct flooding, damaged roots, or every cause of yellow foliage.
Chlorosis is yellowing caused by reduced chlorophyll in plant tissue. On mango leaves it can result from nutrient problems, unsuitable root conditions, water stress, disease, or normal aging, depending on the pattern. Record which leaves are affected first and whether veins stay green before choosing a response. The term describes a visible symptom rather than a diagnosis. Applying a broad fertilizer mix to every yellow tree can overlook waterlogged roots or create unnecessary salt accumulation.
A clone is a plant or group of plants produced from one source through asexual reproduction and generally sharing its genotype, apart from possible mutations. Mango grafting preserves the scion as a clone of the selected source rather than creating a new seedling genotype. Clonal identity does not make all trees perform identically: rootstock, soil, climate, health, and management still matter. A clone is also not automatically disease-free, so propagation hygiene and trustworthy source material remain important.
