Panama disease sexual reproduction. This causes all bananas of a single breed to be nearly genetically identical. The fungus easily spreads from plant to plant because the individual plants' defenses are nearly identical. The disease is dispersed by spores or infected material that travel in surface water. One of the biggest issues in spreading the disease is the means by which new banana plants are planted. Suckers are taken from one plant and clonally propagated to grow new trees. About 30 to 40% of suckers from a diseased plant are infected and not all show symptoms, so the chance of growing a
Crop coefficient Crop coefficient Crop coefficients are properties of plants used in predicting evapotranspiration (ET). The most basic crop coefficient, "K", is simply the ratio of ET observed for the crop studied over that observed for the well calibrated reference crop under the same conditions. formula_1 Potential evapotranspiration (PET), is the evaporation and transpiration that potentially could occur if a field of the crop had an ideal unlimited water supply. RET is the reference ET often denoted as ET. Even in agricultural crops, where ideal conditions are approximated as much as is practical, plants are not always growing (and therefore transpiring) at
