Abstract

Glanded and non-glanded isogenic lines of cotton [Gossypium hirsutum L., var. Empire 61(WR)] were treated with 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) to determine the significance of lysigeneous glands in the tolerance of atrazine by cotton. The presence of lysigeneous glands did not increase atrazine tolerance by cotton or decrease the inhibition of photosynthesis by the herbicide. Detoxication of atrazine by N-dealkylation occurred in both glanded and non-glanded cotton. No significant difference in atrazine metabolism was observed between the two lines. Atrazine metabolism may be a more important factor than the presence of lysigeneous glands in the intermediate tolerance of cotton to atrazine.
