โœฆ Synopsis

Nearly 35,000 individuals of C. capsularis were scored for selfing versus outcrossing in various populations. Different marker loci, such as anthocyanin pigmentation (C/c), serrated leaf (Sr/sr) and fasciated stem (Fs/fs), were used to determine the male gametes which had effected fertilization. The estimates of the outcrossing parameter, ฮฑ were found to differ with years, locations and for the marker locus used in the estimation. The outcrossing for C/c was lowest, the outcrossing for Fs/fs was highest and that for Sr/sr was intermediate. The nature of outcrossing, in general, was nonrandom. Selfing predominated in this species.

The rates of outcrossing in sympatric populations of Ipomoea purpurea and L hederacea were estimated (using electrophoretic markers) to be 70% and 7% respectively. The difference in outcrossing rate is not apparently due to differences in pollinator service received by the species, but is associated

This paper estimates the size of the stability region around zero for quadratic delay difference systems. When the initial disturbance is in the asymptotic stability region, the solution of the initial value problem of the quadratic delay difference system approaches zero. Examples are given for a t
