Abstract
1. Different concentrations of hydrocyanic acid gas gave effects ranging from stimulative to depressive. The maximum of beneficial results was secured from concentrations deadly to insect life, but just a little below the point of first injury to the plant. 2. External factors having important action on the resistance are as follows: (a) wetting the leaves had a beneficial effect on the tomato; (b) reduced temperature and low light intensity during the day preceding fumigation increased resistance. 3. Injury closely paralleled the stomatal movement, increasing as the size of stomatal aperture increased. 4. A higher or lower water supply in the soil affected resistance, through hastening or retarding the growth rate. Rapid growing plants were susceptible to injury, while slow growing plants were more resistant. 5. High reducing sugar content seemed to be correlated with maximum resistance.
