Self-pollination in the production of seed of Buffel grass (Cenchrus ciliaris L.).
The objective of this study wasto compare different forms of pollination on the characteristicsof seed of four varie tie s of Buffel grass. The study was carrie dout in the greenhouse and in the field of UAM Agronomiay Cie ncia s in the Municipa lity of Victoria , Tamaulipa s. Weused four varie tie s of Buffel grass (Comun, Nueces, T-1754and Formidable) which were subjected to two types ofpollination (free and self-pollination). The design used wasa completely randomized blocks design. Day at floweringof male and female organs was measured. In addition,pollen was classified (fertile, intermediate and infertile), andthe effects of self-pollination and free pollination free onthe characteristics of seed were recorded. No effects wereobserved on days at flowering of female organs (P = 0.54), butthe male organs were affected (P = 0.03), so that Formidablevarie ty plants required 2.3 days to mature. The number offertile, intermedia te and infertile pollen grains was not affectedby pollination or varie ty. All seed components were affected(P < 0.01) by the type of pollination, and the plants subjectedto self-pollinating showed the best features. Pollinationaffected the characteristics of the seeds.
