Embodiment 1

[0105] In this experiment, the effect of PGRs on the growth of radish was observed. A total of eighty (80) plants were used in this experiment. Twenty (20) plants were treated with water as controls. Twenty (20) plants were treated with the PGR solution at a rate corresponding to 12 oz / acre. The PGR solution is an aqueous solution comprising 0.015% IAA, 0.005% IBA, 0.009% cytokinin and 0.005% gibberellic acid as active ingredients. Also as inactive ingredients are 1.000% emulsifier, 0.850% surfactant and 0.050% defoamer. A small amount, 0.0084 ml of this solution, was diluted into 100 ml of water and applied to the soil in containers with a surface area of ​​about 1 square foot to correspond to an application rate of 12 oz / acre. Twenty (20) plants were treated with an auxin solution containing indole-3-acetic acid (IAA) at a rate of 0.84 micrograms per square foot of container surface area in 100 milliliters of water. Finally, twenty (20) plants were treated with the cytok...

Embodiment 2

[0115] In this experiment, the effect of PGRs on tomato yield was determined. The tomato variety TSH04, which is a processing tomato, was used. All plants were grown in 5 gallon containers in the greenhouse. Eight plants were used for each treatment. Treatments were applied by air spray to eight plants and soil application to eight plants to allow comparison of PGRs soil application and foliar application. Treat with 6oz / acre PGR solution. Treatment solutions were prepared by diluting 0.0042ml of the concentrate into 100ml of water for soil application or into 50ml of water for foliar application. IAA solutions were prepared by diluting 0.42 micrograms of IAA into 100 ml of water for soil application, or into 50 ml of water for foliar application. Cytokinin solutions were prepared by diluting 0.42 micrograms of kinetin into 100 ml of water for soil application, or into 50 ml of water for spraying on leaves. Solutions containing both IAA and kinetin in a 1:1 ratio were pre...

Embodiment 3

[0123] In this experiment, the effect of PGRs on cucumber internode length was determined. The cucumber variety used was National pickling cucumber distributed by NK Lawn & Garden Co. (Chattanooga, TN). Eight plants were used for each treatment. Treatments were applied to the soil in 5 gallon containers with one plant per container. Treat with 6oz / acre PGR solution. The final PGR solution was prepared by diluting 0.0042ml of concentrate into 100ml of water. IAA solutions were prepared by diluting 0.42 micrograms of IAA into 100 ml of water. Cytokinin solutions were prepared by diluting 0.42 micrograms of kinetin into 100 ml of water. Finally, plants were treated with N-Large at 6oz / acre. The treatment solution was prepared by diluting 0.0042 ml of a commercial solution into 100 ml of water. N-Large is a formulation containing 4% gibberellin (GA3). Water was used as a control. Treatments were applied to the soil at planting and weekly thereafter. Twenty-one (21) days a...

Abstract

In agriculture when temperature and moisture deviate from the norm two things happen, plant growth suffers and disease flourishes. The Stoller model for plant growth states that proper hormone balance is necessary for optimum growth and performance. When growth conditions deviate from the norm, hormone balance is altered and plant growth suffers. This invention presents evidence to support this model and explain the relationship between hormone levels and plant growth. A clear understanding of this relationship will facilitate crop treatments aimed to eliminate these problems. Although we cannot control the climate, we can control the damage caused by environmental stresses by manipulating the levels and / or ratio of plant hormones in the different plant tissues. By adjusting the levels and / or ratios of hormones, particularly auxin and cytokinins in the root tissue, we can assist the plant in overcoming or compensating for this environmental stress.

Description

Background of the invention [0001] I. Field of Invention [0002] The present invention generally relates to methods of increasing plant growth and crop productivity by modulating phytohormone levels and / or ratios. These methods are also useful for increasing the resistance of plants to insect and pathogen attack and, at the same time, improving plant growth by controlling phytohormones. More specifically, the present invention relates to methods of achieving those goals by administering to plant tissue an effective amount of one or more phytohormones. Alternatively, these goals are achieved by applying to the plant tissue other substances that affect the level of one or more phytohormones in the plant tissue, bringing the hormone into a desired range. [0003] I. Background description [0004] Plant hormones have been known and studied for many years. Plant hormones can be assigned to one of five classes: auxins, cytokinins, gibberellins, abscisic acid, and ethylene. Et...
