18 Days after perithecia appearance was the best time to isolate ascospores, although there were differences between crosses. The highest survival percentage of ascospores could reach up to 85. 5% during this period.
观察发现,虽然不同杂交组合间有一定差异,分离稻瘟病菌子囊孢子的适宜时期,一般在子囊壳开始出现后7~18天之间;在此期间分离出的子囊孢子成活率最高可达85.5%。
-
At first, optimization for the perfect stage production of M. grisea was investigated in vitro. The number of perithecia and ascospores, the percentage of viable ascospores were markedly increased when juice of mature tomato was used, pH was adjusted around 5. 5 and 0.1%CaCO〓 was added in oatmeal tomato agar medium.
本研究首先选用自然成熟的番茄榨汁和燕麦片作为培养基的主要组分,通过调节培养基pH值在5.5左右并添加0.1%CaCO〓途径优化了稻瘟病菌有性世代形成的条件,显著增加了稻瘟病菌子囊壳形成的数量和子囊孢子的成活率。
-
When they were cultured with KA3(MAT1-1), KA9(MAT1-2) or Z46(MAT1-2),the numbers of strains which can form perithecia are 22,6 and 4, respectively.
研究结果表明:35个双交配型菌株自交都没有形成子囊壳,分别与KA3(MAT1-1)、KA9(MAT1-2)和Z46(MAT1-2)杂交形成子囊壳的菌株数为22,6和4。
-
Two isolates ( BO1218 BO1199)can form perithecia when they were cultured with KA3(MAT1-1) and Z46(MAT1-2).Three isolates ( BO1218 BO1199 and BO1535) can form perithecia when they were cultured with KA3(MAT1-1) and KA9(MAT1-2).These five isolates have MAT1-1 and MAT1-2 which are functional.
其中2个菌株(BO1218、BO1199)与KA3和Z46杂交都形成子囊壳,3个菌株(BO1643、BO1563和BO1535)与KA3和KA9杂交都形成子囊壳,表明这5个菌株中存在MAT1-1和MAT1-2,并且具有完整的功能。

Further, crosses among fertile isolates from the above four provinces were made.One of fourteen crosses produced perithcia,but none ascospores were generated.
用不同交配型的可育菌株进行互交,14个组合中只有1个组合产生子囊壳,但没有形成成熟的子囊孢子。
