Cotton Boll Ripening Patents (Class 47/5)
  • Patent number: 7634870
    Abstract: The growth and development of cotton is enhanced by an application of relatively low concentrations of a cytokinin to cotton seed or to a growing cotton plant at a stage of growth between the cotyledon stage and the six-leaf stage. Application of the cytokinins is effective to elicit one or more effects in the resultant plant including reduced apical dominance, increased rate of development of fruiting branches, decreased time to first bloom, increased number of cotton squares formed, thickening of the hypocotyl, reduced rate of leaf wilting, reduced water usage, and increased root development.

  • Patent number: 6594950
    Abstract: A wick applicator for applying agricultural liquid chemicals to crops, weeds and other vegetation. The wick applicator includes an elongated tube for holding and dispensing liquid chemicals. An air inlet extends from the tube and is communicatively open to the internal chamber of the tube. To meter or regulate the flow of liquid chemicals from the elongated tube, a non-variable fixed size orifice is disposed in the air inlet tube. In use, the wick applicator is useful in applying a growth regulating composition to the upper portion of a cotton crop. This is achieved by setting the wick applicator at a selected height and then moving it through a cotton field at that height and in the process, engaging and mopping the portion of any cotton crop in its path.

  • Patent number: 6563021
    Abstract: Methods are disclosed to achieve an improvement in the characteristics and yield of cotton fibers. In one method, a cotton plant of the genus Gossypium in seed form or in growth stage is treated with a brassinosteroid. In another method, an ovule culture is prepared from a cotton plant of the genus Gossypium in a brassinosteroid-containing liquid medium. Cotton fibers with improved fiber characteristics are obtained from the cotton bolls of the treated plant or from the cultured ovules.

  • Patent number: 5361457
    Abstract: A device for de-linting cotton seeds is described that is of simple construction, does not damage the seeds and is antipolluent. The device comprises a unit provided with super-imposed discs spaced by a distance of the same order as the larger dimension of an at least partially linted cotton seed, the upper disc being fixed and the lower disc being rotary. Seeds are fed through a central opening in the upper disc and subject to friction between the discs as they migrate outwardly to the periphery where they are discharged and the lint removed is expelled from the device by an exhaustor. The lower discs are coated with a relatively rough surfaced rubber-like material and the lower discs are coated with a similar material formed with a plurality of finger-like projections whereby the seeds are subject to coarse friction from the lower disc while their toward migration is controlled by the retaining fingers. The device may have a plurality of such units in series.
