The ecological mechanism of fertility transition for a thermo-sensitive genic male sterile line,Qiong-68 ms,was evaluated by means of sowing by stages,investigating leafage and detecting the fertility of pollen.

采用分期播种、叶龄调查以及花粉镜检等方法，对玉米温敏核雄性不育系琼68 ms 育性转换的生态机制进行了研究，发现琼68 ms的育性变化主要受温度影响，日最高温度是其育性转换的主要因素，表现为高温不育，低温可育，育性转换的温度范围为30~33℃，雄穗发育的小穗分化期是对温度敏感的关键时期。

Firstly, the connection matrices are strongly connected Boolean matrix, it is shown that the maximum length of limit cycles for FBAM is the period index of the product of the connection matrices. Thus, the maximum limit cycle is reachable. Secondly, two strongly connected components are connected by walks, it is proved that the maximum length of limit cycles for FBAM is the max. of the period index of the two strongly connected components if they are prime, otherwise, it is the least common multiple of the two period index. Finally, n strongly connected component are connected in succession, the method for computing the maximum length is described. By different patterns are presented to the networks, diminishing the number of the strongly connected components until only two components.

第一，连接权矩阵为强连通布尔矩阵，此时模糊双向联想记忆网络的最大极限环长度为连接权矩阵乘积的周期指数，从而极限环具有可达性；第二，两个强连通分支有路径连接，此时如果两个强连通分支的周期指数互素，那么网络的最大极限环长度为其最大者，否则，网络的最大极限环长度就等于二者的最小公倍数；第三，n个相邻强连通分支有路径连接，给出了计算最大极限环长度的方法，通过激发模式的变化，逐渐减少强连通分支的个数，直到只有两个分支。
