野燕麦（Avena fatua L.）和春小麦（Triticum aestivum L.）测量、切片、染色和压扁，用于比较生长和有丝分裂活性。野燕麦地上部组织比根组织更容易受到二烯二酸蒸汽的伤害。第一片叶基部的分生组织明显比茎尖组织更脆弱，因为它表现出更多的分裂和更多的异常。Triallate的效果相似，但不太明显。小麦地上部组织对二烯丙酸的敏感性也高于根组织。有丝分裂活性降低和芽抑制表明了这一点。即使在高浓度下，在小麦中也几乎没有观察到异常。结果与Triallate相似。根系和地上部的测定表明，小麦对三烯丙的耐性强于二烯丙。在不影响有丝分裂的浓度下，野燕麦和小麦都发生了芽抑制。因此，使用二烯丙酸或三烯丙酸引起的有丝分裂损伤似乎是次要的，主要影响是细胞伸长或扩张的某些阶段。
After 3 days or more germination in 5-(2,3-dichloroallyl) diisopropylthiocarbamate (diallate) or S-(2,3,3-trichloroallyl)diisopropylthiocarbamate (triallate) vapor, shoots and roots of wild oat (Avena fatua L.) and spring wheat (Triticum aestivum L.) were measured, sectioned, stained, and squashed for comparison of growth and mitotic activity. Shoot tissue of wild oat was damaged more readily than root tissue by diallate vapor. The meristematic tissue at the base of the first leaf was apparently more vulnerable than stem apex tissue since it exhibited more divisions and a greater number of abnormalities. The effect of triallate was similar but less pronounced. Shoot tissue of wheat also was more sensitive to diallate than root tissue. This was indicated by reduced mitotic activity and by shoot inhibition. Few abnormalities were observed in wheat even at high concentrations. Results were similar with triallate. Root and shoot measurements indicated that wheat was more tolerant to triallate than to diallate. Shoot inhibition occurred in both wild oat and wheat at concentrations that did not affect mitosis. Mitotic damage from the use of either diallate or triallate thus appeared to be of secondary importance, the major effect being on some phase of cell elongation or expansion.
