研究小麦品种对小麦叶锈菌水平抗性,需要计算产孢量。我们以小麦叶锈菌夏孢子粉为材料进行试验,初步找到两种较为准确、简便易行的方法——称重法和直接计数法。两种方法均需在大田(或温室)定品种、定单株、定叶片,数单病叶片的孢子堆数的基础上计算产孢量。 To study the level of resistance of wheat cultivars to Puccinia triticina, it is necessary to calculate the amount of sporulation. We tested wheat leaf rust spore powder as raw material, initially found two more accurate, simple and easy method - weighing method and direct counting method. Both methods require calculation of sporulation numbers on the basis of the number of spores in the field (or greenhouse) set varieties, order lines, fixed leaves, and single disease leaves.
