Effect of crushing on the respiratory drift of pasture ...

Materials tested were white clover, lucerne and short rotation ryegrass at different stages. Crushing often stimulated respiration but the increase was not proportional to the amount of injury. Drying was more rapid after crushing so that respiration stopped sooner. Dry matter losses after crushing were less but not significantly so than after normal drying.-J. C. Rigg.

One leaf from each twig was kept separately in an ice box for the estimation of Chl. Chl concentration was estimated according to Arnon (1949) by crushing 0.1g of fresh leaf in 10ml of 80% acetone, the absorbance (D) of the extract was then measured at 645 and 663nm wavelengths using 80% acetone as blank. The leaf collection protocol was the same across time and space.

The effect of crushing on the drying of pasture plants.

Crushing leguminous pasture plants greatly reduced the time required for drying, particularly for succulent stems. The time taken to dry clover to 30 per cent. moisture was reduced from 60 to 40 hr. with light crushing and to 29 hr. with heavy crushing, and for lucerne from 101 to 50 and 26 hr., respectively.

Even when not deposited as abrasive spines, Si can still make plants hard to digest, if for example these deposits prevent herbivores crushing cells to extract nutrients, as hypothesized by Hunt et al. (2008).
