The most harmful of gaseous air pollutants include ozone (03), sulphur dioxide (SO2) and nitrogen dioxide (N02). These three pollutants are responsible for up to 90% of the total crop losses due to air pollution (Heck et al. 1981). Reduction in crop yield is one of the most common consequences of pollutant-crop interaction (Koziol & Whatley, 1984; Treshow, 1984). Mean yields of four soya-bean cultivars, York, Dare, Cutler and Clark, grown in open-top chambers with non-filtered air, were reduced by 20% compared with those grown in carbon-filtered air (Kohut et al. 1982). The major components affected were number of pods, number of seeds per filled pod and weight of seeds; a linear reduction in seed weight per plant was reported with increasing concentration of O3.

Soya bean plants (cv. Lee) were grown at high and low atmospheric humiditiees in controlled environments. A constant level watering system ensured an adequate supply of water at all times. Bean yields decreased at the low humidity as a result of a reduction m pod number and thus bean number, which was only partly compensated by a small increase In bean weight The reduction In pod number was related to floret abortion rather than pod abortion, and was possibly a consequence of reduced photosynthate supply. The level of humidity did not affect the protein or oil content of the seed. The lower humidity also reduced the dry weights of stems and total tops and the number of nodes per plant. The humidity level before or after flowering alone did not affect bean yield, but the humidity from the start of flowering onwards did affect the number of beans per plant. The possible significance of the results for soya bean production In the Australian environment is considered.

SummaryThe cold promoted activation of factor VII occurs in parallel with an activation of a plasma arginine esterase, and, on inhibition of the cold activation of factor VII, the esterase activation also decreased. The inhibitor pattern supported our theory that the arginine esterase that is activated in the cold activation of factor VII is plasma kallikrein.The cold activation of factor VII was completely inhibited with soya bean trypsin inhibitor in doses that did not interfere with the contact activation. On the other hand, inhibition of the contact activation with hexadimethrine bromide did not interfere with the cold activation of factor VII except when this was kaolin induced. Contact and cold activation therefore appear to represent two different pathways for the activation of factor VII. The cold activation reaction is probably mediated by the activation of plasma prekallikrein, and inhibition of the plasma kallikrein activity correlates with the inhibition of the cold promoted activation of factor VII.
