    Abstract: A total of twenty leaf rust resistance genes (Lr genes) were postulated in nine Egyptian wheat cultivars based on infection types (ITs) expressed on the tested cultivars by 72 Puccinia triticina pathotypes compared with the ITs expressed on the monogenic lines. The most carrier genes cultivars were Giza168 and Misr1 each may contain five genes i.e.... Show More

    Abstract: Reproductive morphology of araucarian samara is revised revealing a carpellate structure of the stone. In A. columnaris it is formed by a supercoiled spermophyll (‘seed scale’), with a stigmatic apical lobe. This structure is analogous to the ‘classical’ peltate carpel of flowering plants. Stone opens with two apical pores. Pollen germinates on the... Show More
