“…In contrast, the pollen donor diversity in Rhamnus alpinus has been reported to affect on different reproductive components of F 1 progeny e.g. embryo size (Nakamura and Stanton, 1989), seed size, germination rate, seedling vigor and survivorship (Banuelos and Obeso, 2003), and the embryos developments (Diggle et al, 2010). …”

“…For instance, in Raphanus sativus seed growth rate (Diggle et al, 2010), and embryo/seed development rate (Marshall and Diggle, 2001) were shown to be affected by both maternal and paternal parents. This simultaneous impact of both paternal and maternal on progeny performance indicates genotypic interactions (Marshall et al 2000).…”

These studies indicated that the levels of offspring performance in plants are mainly controlled by maternal parent, while the impact of paternal parent on the progeny performance has been less investigated (Holland et al, 2009).…”

Studies on the parental role on progeny performance have mostly focused on the maternal parent, while less attention was given to the paternal parent. This study investigated the impact of paternal pollen sterility (ranging from 3.1 -to 77.2%) on F 1 seed germination and progeny survivorship in Fragaria (strawberry, Rosaceae) using controlled crosses. In crosses within F. vesca ssp. vesca the paternal pollen sterility was not correlated with F 1 seed germination (N = 14, p > 0.074) and progeny survivorship (N = 14, p > 0. 0.710). Paternal sterility in crosses between F. vesca ssp. vesca and F. vesca ssp. monophylla did not affect on F 1 seed germination (N = 7, p > 0.295) and progeny survivorship (N = 6, p > 0.812). Similarly, no correlation was found between father pollen sterility and F 1 seed germination (N = 6, p > 0.924) and progeny survivorship (N = 6, p > 0.215) in crosses between F. vesca ssp. americana and F. vesca ssp. vesca. Furthermore, crossing different maternal plants by pollen of the same paternal plant in all three cross types produced progeny with variable levels of F 1 seed germination and survivorship. These results indicate the crucial role of maternal plant on progeny performance and support the general idea of the importance of maternal rather than paternal parent on progeny performance.

Pada persilangan lobak liar (Raphanus sativus), tetua betina berpengaruh terhadap perkembangan embrio, namun pengaruh tersebut sangatlah bergantung pada peran tetua jantan sebagai donor tepung sari dan peran tetua jantan tersebut dapat berubah-ubah setiap saat (Diggle et al, 2010). Kondisi tetua betina karena adanya cekaman faktor lingkungan, seperti terjadinya kekurangan air, berpengaruh terhadap proses perkembangan buah dan biji karena menurunnya sumber-sumber energi yang diperlukan bagi proses perkembangan buah dan biji (Gehring & Delph, 2006).…”

ABSTRAKPada proses persilangan, gejala genetik berupa pengaruh langsung tetua jantan sebagai sumber tepung sari terhadap penampilan buah dan biji hasil persilangan disebut sebagai gejala xenia. Tujuan penelitian adalah mengetahui pengaruh tetua jantan terhadap karakter komponen buah dan biji hasil persilangan beberapa genotipe kakao mulia. Penelitian dilakukan di Afdeling Kalikempit PTPN XII, Desa Tulungrejo, Kecamatan Glenmore, Kabupaten Banyuwangi, Jawa Timur, pada ketinggian tempat 340 m dpl dengan jenis tanah Latosol dan tipe iklim C, mulai bulan Mei sampai Desember 2014. Enam perlakuan kombinasi persilangan yang diuji adalah (1) DR 38 x DR 1, (2) DR 38 x DR 38, (3) DR 2 x DR 1, (4) DR 2 x DR 2, (5) DRC 16 x DR 38, dan (6) DRC 16 x DRC 16. Pengamatan dilakukan terhadap karakter kuantitatif dan kualitatif komponen buah dan biji. Hasil penelitian menunjukkan tetua jantan DR 1 yang disilangkan dengan tetua betina DR 2 berkontribusi terhadap peningkatan bobot buah segar (34,70%), bobot biji segar/buah (44,32%), dan bobot satu biji segar (31,00%), serta terhadap bentuk ujung buah dan keberadaan leher botol. Tetua jantan DR 38 yang disilangkan dengan tetua betina DRC 16 berkontribusi terhadap peningkatan bobot buah segar (47,01%) dan biji (31,22%), serta terhadap warna buah matang dan keberadaan leher botol. Seluruh kombinasi persilangan menghasilkan warna biji putih di atas 85% sehingga termasuk kualitas baik. DR 2 dan DR 38 dapat digunakan sebagai tetua jantan untuk meningkatkan jumlah biji dengan warna putih.

“…For example, when resources are limited plants produce smaller seeds (Vaughton and Ramsey 1997) or abort seeds selectively (Stephenson 1981, Sun et al 2004, Wise and Cummins 2006. Paternal identity and pollen traits have indeed been shown to affect seed traits (Diggle et al 2010).…”

Effects of soil resources on expression of a sexual conflict over timing of stigma receptivity in a mixed‐mating plant

While environmental factors strongly influence plant growth and reproduction, less is known about environmental effects on sexual selection and sexual conflict. In this study on mixed‐mating Collinsia heterophylla we investigated whether soil resource environment affected traits associated with sexual conflict. In C. heterophylla a sexual conflict over timing of stigma receptivity occurs. Early stigma receptivity benefits pollen parents by securing paternity while late stigma receptivity benefits female fitness in terms of increased seed production. We performed hand‐pollinations combining recipients and donors grown either in high or low resource environments and asked whether these treatments influenced sexual conflict traits – recipient‐ and donor‐based influence on timing of stigma receptivity – and conflict costs related to reduced early seed production. We also asked whether resource environment affected eight traits related to general fitness and mating system. Sexual conflict‐associated traits – timing of stigma receptivity and seed production – were generally unaffected by resource environment. While no universal effect of resources was detected, we did observe donor‐specific responses to environment, suggesting that environment can nonetheless contribute to variation in timing of stigma receptivity. Recipients grown under low resources showed pronounced differences among donors for number of seeds per capsule, indicating that recipients favour some donors over others under resource‐low conditions. Moreover, high resources increased number of flowers but reduced pollen germination rate, while other traits were unaffected, indicating variation in the response to resource environment for fitness‐ and mating system‐traits. Our results suggest that even though soil resource environment had a low impact on the sexual conflict traits and related costs in C. heterophylla, it generated variability in pollen donor‐influence on this trait and in recipient sorting among donors. Thus, it is possible that both sexual conflict and sexual selection is affected by environmental factors not only in animals but also in plants.
