Abstract

Research was conducted to determine the influence of temperature on triallate absorption and metabolism in triallate-tolerant durum wheat (Triticum durum L. 'Monroe'), moderately tolerant Hard Red Spring (HRS) wheat (Triticum aestivum L. 'Coteau'), and susceptible HRS wheat, Alex. Uptake of 14C-triallate by the shoot was greater at 24 than at 8 °C by all species. Triallate uptake as influenced by soil temperature is a factor affecting triallate phytotoxicity to wheat. However, Monroe shoot meristematic tissue contained more 14C-label than Alex or Coteau, indicating that 14C-label content in the meristematic tissue was not related to triallate tolerance. Further, the coleoptile tissue of Monroe contained less 14C-label than Alex or Coteau. The coleoptile tissue did not prevent 14C-label entry into shoot tissue. Coleoptile tissue did not seem to be a factor influencing triallate tolerance. 14C-triallate concentration in the shoot related to triallate tolerance at both 8 and 24 °C. Triallate metabolism was apparently involved in differential tolerance among cultivars as the more tolerant Monroe and Coteau had more 14C-metabolites than susceptible Alex. Key words: Wheat, triallate, herbicide, temperature, absorption, metabolism
