3-When mineral nutrients are abundant (except nitrates, which are relatively less than in class 2), vegetativeness is reduced and carbohydrates accumulate, resulting in fruitfulness and a moderate amount of vegetative growth.ħ 4- When minerals nutrients are abundant (except nitrates, which are relatively even less than in class 3), the result is a marked accumulation of carbohydrates and a suppression of both vegetativeness and fruitfulness.Ĩ How pruning effects growth & fruitfulness 4- Root growth is decreased by a reduction in the amount of energy-producing food manufactured.ĥ Four classes of growth & fruit responseġ- When mineral nutrients (including nitrates) are abundant but a little or no carbohydrate supply is available, the result is weak vegetative growth and a nonfruitful plant.Ħ 2-When mineral nutrients (including nitrates) are abundant and a carbohydrate supply is available, the result is a strong vegetative growth but little or no fruit. 2- A greater % of reserve foods is made available to the reduced number of growing points & fruits.Ĥ 3- A decrease evaporation results in conservation of soil moisture & allows a smaller tree to thrive longer under limited water conditions.
Used for early spring growth until leaves are present on the tree.ġ- The food supply is decreased by reduction of the manufacturing surface.
