Abstract

The present invention describes a composition including a mixture of L- and D-pyroglutamate stereoisomers in a ratio of L to D of from about 80:20 to about 97:3 , and, a carrier medium for application of the L- and D-pyroglutamate stereoisomers to a target plant. The composition can also be used as a germination medium and may be incorporated into a seed coat for assisting in germination. The present invention further describes a method of increasing the agronomic performance of a target plant by treating a target plant with a composition including a mixture of L- and D-pyroglutamate stereoisomers in a ratio of L to D of from about 80:20 to about 97:3 and a carrier medium for said L- and D-pyroglutamate stereoisomers.

Use of prolines for improving growth and other properties of plants and algae

Patent Unkefer, Pat J.; Knight, Thomas J.; Martinez, Rodolfo A.

Increasing the concentration of prolines, such as 2-hydroxy-5-oxoproline, in the foliar portions of plants has been shown to cause an increase in carbon dioxide fixation, growth rate, dry weight, nutritional value (amino acids), nodulation and nitrogen fixation, photosynthetically derived chemical energy, and resistance to insect pests over the same properties for wild type plants. This can be accomplished in four ways: (1) the application of a solution of the proline directly to the foliar portions of the plant by spraying these portions; (2) applying a solution of the proline to the plant roots; (3) genetically engineering the plant and screeningmore »« less

Apparatus for silicon web growth of higher output and improved growth stability

Patent Duncan, Charles S [Penn Hills, PA]; Piotrowski, Paul A [Monroeville, PA]

This disclosure describes an apparatus to improve the web growth attainable from prior web growth configurations. This apparatus modifies the heat loss at the growth interface in a manner that minimizes thickness variations across the web, especially regions of the web adjacent to the two bounding dendrites. In the unmodified configuration, thinned regions of web, adjacent to the dendrites, were found to be the origin of crystal degradation which ultimately led to termination of the web growth. According to the present invention, thinning adjacent to the dendrites is reduced and the incidence of crystal degradation is similarly reduced.
