Tropical pasture establishment. 5. Improved handling of chaffy grass seeds: options, opportunities and value


, : Tropical pasture establishment. 5. Improved handling of chaffy grass seeds: options, opportunities and value. Tropical Grasslands 27(4): 314-326

Many useful grasses have 'chaffy' seeds characterized by a range of appendages: awns, sterile spikelets, and surface hairs or bristles. En masse, chaffy seeds are light and bulky, and do not flow freely because the individual units tend to become entangled. These attributes add to costs of seed cleaning, testing, storage and transport, and make it impossible to sow chaffy seeds evenly through conventional seeders. Examples are given of the structural diversity among chaffy grass seeds.

Morphine (Mor) tolerance has been attributed to a reduction of opioid-adrenergic antinociceptive synergy at the spinal level. The present experiments tested the interaction of intrathecally (i.t.) administered Mor-clonidine (Clon) combinations in...
