Abstract

The effects of seven s-triazines on the opening of the hypocotyl hook of cotton (Gossypium hirsutum L. ‘DPL Smooth Leaf’) and the germination of lettuce seed (Lactuca sativa L. ‘Grand Rapids’) were investigated. The s-triazines used were ametryne [2-(ethylamino)-4-(isopropylamino)-6-(methylthio)-s-triazine], atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine], cyprazine [2-chloro-4-(cyclopropylamino)-6-(isopropylamino)-s-triazine], prometone [2,4-bis (isopropylamino)-6-methoxy-s-triazine], prometryne [2,4-bis (isopropylamino)-6-(methylthio)-s-triazine], propazine [2-chloro-4,6-bis(isopropylamino)-s-triazine], and simazine [2-chloro-4,6-bis(ethylamino)-s-triazine]. All triazines except cyprazine stimulated germination of lettuce seed given 4 min of dim red light but none were stimulatory in the dark. Maximum stimulation occurred with 1 X 10-8 to 1 X 10-12 M s-triazine. All triazines except atrazine and cyprazine stimulated the opening of cotton hypocotyl hooks given 2 hr of dim red light of the s-triazines tested. Prometryne and ametryne were the most stimulatory to hook opening in the light and the most inhibitory in the dark. Their effects paralleled those of kinetin.
