Glucocorticoid action on the growth and development of insects.

Cortisol increased growth and differentiation in the large milkweed insect (Oncopeltus fasciatus). The glucocorticoid significantly increased the growth of the insect as analyzed by wet and dry weights. Cortisol also stimulated the development of the insects over that of the controls during the six day bioassay.

Beta-zeacarotene of the bovine ovary.

An investigation of the carotenoids from a bovine ovary extract has revealed the presence of three Porter-Lincoln pathway intermediates of which beta-zeacarotene is previously unreported. Analysis using spectrophotometric and chemical tests reveals beta-zeacarotene (2.14 micrograms/g), alpha-carotene (0.

Prostaglandin inhibitors and the development of mung bean seedlings.

The effect of cortisol and prostaglandin inhibitors on the growth and development of germinating mung bean, Vigna radiata L. Wilzek, cv. Jumbo was investigated.

Effect of gibberellic acid on production characteristics of aged and force molted chickens in cages.

Production characteristics of individually caged 72-week-old brown egg type hens or 86-week-old hens of a similar strain that had previously been subjected to different watering systems (continuous flow cups vs. intermittent flow troughs) and the stress and recovery of a forced molting program were evaluated in two trials over a 4 to 5-week interval following 6 alternate day subcutaneous injections (2.4 mg/bird) of gibberellic acid (GA3).
