Abstract
The invention provides a compound of formula I: wherein X, Y, Z, R1, R2, and X+ have any of the values described in the specification. The compounds are useful to increase plant growth and/or to increase harvest yield.
Claims18
A method comprising, increasing growth or harvest yield by providing H2S to a plant or a seed through degradation of a compound of formula I;
- wherein:
- Y is O;
- Z is O;
- R1 is C3-alkyl, C4-alkyl, C5-alkyl, C6-alkyl, C7-alkyl, C8-alkyl, C9-alkyl, or C10-alkyl, and R2 is C3-alkyl, C4-alkyl, C5-alkyl, C6-alkyl, C7-alkyl, C8-alkyl, C9-alkyl, or C10-alkyl, and
- X+ is a suitable cation
- wherein the plant is a pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, soybean, or radish;
- and
- wherein the seed is a seed of a plant selected from the group consisting of pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, sugar beet, barley, oats, wheat, potato, corn, soybean, and radish.
A method comprising, increasing growth or harvest yield by providing H2S to a plant or a seed through degradation of a compound of formula:
- wherein X+ is a suitable cation;
- wherein the plant is a pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, soybean, or radish;
- and
- wherein the seed is a seed of a plant selected from the group consisting of pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, soybean, and radish.
A method comprising, increasing growth or harvest yield by providing H2S to a plant or a seed through degradation of a compound of formula:
- wherein X+ is a suitable cation;
- wherein the plant is a corn or soybean;
- and
- wherein the seed is a seed of a plant selected from the group consisting of a corn and a soybean.
A method comprising, increasing harvest yield by providing H2S to a plant or a seed through degradation of a compound of formula:
- wherein X+ is a suitable cation;
- wherein the plant is a pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, radish, or soybean;
- and
- wherein the seed is a seed of a plant selected from the group consisting of pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, soybean, and radish.
A method for increasing the harvest yield of a plant comprising, contacting the plant with a compound of formula:
- wherein X+ is a suitable cation;
- wherein the plant is a pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, soybean, or radish.
A method for increasing the harvest yield of a plant that grows from a seed, comprising contacting the seed with a compound of formula:
- wherein X+ is a suitable cation;
- wherein the plant is a pea, lettuce, tomato, cucumber, green bean, broccoli, squash, beet, onion, sugar, corn, sugar beet, barley, oats, wheat, potato, soybean, or radish.
