Regeneration of both plant tissues and transgenic plant tissues using a new plant hormone, 5-bromoindole-3-acetic acid

A method for enhancing a plant growth response comprising the step of growing the plant in the presence of a growth-enhancing, effective amount of a composition comprising 5-bromoindole-3-acetic acid, or a salt, an ester or an amide derivative thereof, wherein said plant growth response is selected from the group consisting of:

• stimulating seed germination:
• breaking of dormancy:
• increasing wields;
• hastening ripening and color production in fruit;
• increasing flowering and fruiting;
• stimulating shoot formation:
• inducing callus development;
• inducing rooting;
• causing cell proliferation;
• increasing hardiness;
• increasing the dry weight content of plants or plant parts;
• and
• wherein said plant is selected from the group consisting of:
• a whole plant;
• a transformed plant;
• a part of a plant;
• a locus of a plant;
• a cell of a plant:
• a tissue of a plant;
• an explant;
• a seed or seeds of a plant;
• a suspension culture or a tissue culture of a plant;
• a culture of calli;
• a culture of protoplasts;
• a culture of embryos;
• a culture of organs;
• or a culture of organelles;
• such that an enhancement of said plant growth response occurs in said plant in the presence of said composition when compared to a corresponding plant in the absence of said composition.
