Juglans neotropica being ripe. The sap of the fruit husk is a strong dye and can stain hands and clothing. The nut inside is within a much harder and more difficult to crack shell than Persian walnuts, but the meat inside is comparable in flavour, perhaps a bit sweeter. "Tocte", the fruit of the Andean walnut, are often sold in the farmer's markets of Ecuador. The process of husk removal often stains the shells of the nuts black. Like all walnuts, unripe fruit husks produce a strong yellow dye that does not require mordant; ripe fruits produce a strong red to brown
Fruit tree pollination Fruit tree pollination Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination, so pollinizer trees are planted in orchards. The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by hand-pollination or by using a pollen sprayer). Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created
