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.

Cultivar Description

Karat is a winter wheat (Triticum aestivum L. em. Thell.) with bread making quality, high grain yield, and adequate straw strength. It is moderately susceptible to powdery mildew (caused by Erysiphe graminis D.C. ex. Merat f. sp. tritici Marchal) and septoria leaf and glume blotch (caused by Septoria nodorum Berk.) and is suited for production in areas of Eastern Canada where winter survival is not a problem.

Foram estudados sete cultivares de trigo (Triticum aestivum L. ), um de trigo duro (Triticum durum L.), sete de triticale e dois de centeio (Secale cereale L.), em soluções nutritivas contendo quatro níveis de alumínio tóxico. A tolerância foi medida pela capacidade de as raízes primárias continuarem a crescer em soluçâo sem alumínio após um período de 48 horas em solução contendo uma concentração conhecida de alumínio. A temperatura de 28 ± 1 °C foi mantida constante nas soluções durante o experimento. Os cultivares de centeio, Goyarowo e Branco, foram tolerantes a 20mg/ litro de Al3+; os de trigo, Siete Cerros, Tobari-66 e Cocorit, foram sensíveis a 5mg/lítro de alumínio, porém BH-1146, IAC-5, BR-1 e IAC-18 foram tolerantes e, IAC-17, moderadamente tolerante a essa concentração de alumínio; os cultivares de triticale, PFT-763, TCEP-77142, PFT-764, TCEP-75709, Cynamon, TCEP-77138 e TCEP-77136, foram tolerantes a 5mg/litro de Al3+. Todos os cultivares de trigo e triticale foram sensíveis a 10mg/litro de Al3+.

Triticum Aestivum L

Foi estudado o comportamento diferencial de 12 genótipos de trigo comum (Triticum aestivum L.), um genótipo de trigo duro (Triticum durum L.), e um de triticale (Triticosecale sp) em soluções nutritivas de tratamento contendo duas concentrações salinas (1/5 e 1/10 da completa) e seis concentrações de alumínio ( 0, 2, 4, 6, 8 e 10 mg L-1), à temperatura de 25 ± 1ºC e pH 4,0. Foram utilizadas dez plântulas por parcela e quatro repetições. A tolerância foi medida pela capacidade de as raízes primárias continuarem a crescer em solução sem alumínio, após permanecer 48 horas em solução nutritiva completa, contendo uma concentração conhecida de alumínio combinada com cada uma das concentrações salinas. Os genótipos de trigo comum IAC-289, IAC-350 e IAC-370 e a cultivar controle Anahuac, e os genótipos de trigo duro IAC-1003 e de triticale IAC-5 foram os mais sensíveis a níveis crescentes de Al3+nas soluções nutritivas de tratamento e, portanto, somente seriam indicados para cultivo em solos corrigidos. Os genótipos de trigo comum IAC-24 e IAC-378 e a cultivar controle BH-1146 destacaram-se pela tolerância à toxicidade de Al3+, com potencial para uso em solos ácidos e como fontes genéticas de tolerância nos futuros cruzamentos. Os sintomas de toxicidade de alumínio foram maiores com a elevação da concentração de alumínio e da diminuição das concentrações de sais da solução nutritiva para todos os genótipos estudados.

INHERITANCE OF THE TYPE OF SOLID STEM IN GOLDEN BALL (TRITICUM DURUM): II. CYTOGENETICS OF THE RELATION BETWEEN SOLID STEM AND OTHER MORPHOLOGICAL CHARACTERS IN HEXAPLOID F5 LINES OF A HYBRID WITH RESCUE (T. AESTIVUM)

Solid Stem

Cytogenetic analysis of selected F5 lines of the pentaploid hybrid, Rescue (Triticum aestivum L. emend. Thell.) × Golden Ball (T. durum Desf.) showed that chromosome XVI is the member of the D genome of Rescue that prevents transfer of the more solid top culm internode of Golden Ball to hexaploid segregates. It also produces a lax spike. Chromosome XX, which is the D-genome chromosome mainly responsible for the hollowness of hollow-stemmed hexaploids, probably has little effect in Rescue. Long awns were associated with low chromosome number but not with stem solidness or dense spike; therefore, the chromosome that suppresses awn development is probably not XVI.Three 42-chromosome segregates from the cross were more solid in the top internode than Rescue, presumably because of segregation of genes in the A and B genomes. It is unlikely, however, that a fully hexaploid segregate with a top internode as solid as that of Golden Ball can be selected from this hybrid.
