“…Many studies also reported similar findings in which pollination rate was decreased in the less flowered populations; as well as those observed in Genista spp. (Tsaliki and Diekmann 2011), Aquilegia canadensis (Herlihy and Eckert 2007), Vigna caracalla (Etcheverry et al 2008) and Helianthemum caput-felis (Agullo et al 2015).…”

“…The components of floral traits, such as plant size, plant age, floral structures and sexual organs arrangement (Arroyo et al 2006;Herlihy and Eckert 2007;Etcheverry et al 2008;Ortigosa and Gomez 2009;Barrett 2011;Tamla et al 2012;da Cruz et al 2014), altogether arrange floral display within population. Differences on floral display might be resulted in different pollinators and pollination behavior, which affect mating systems and genetic diversity (Herlihy and Eckert 2007;Arroyo et al 2006;Barrett 2011;Kartikawati et al 2013), reproductive outputs (Tsaliki and Diekmann 2011;Nadia and Machado 2014) and population fitness (Provan et al 2008;Weber and Kolb 2013). Furthermore, they might exhibit different response to the environmental triggers (Richardson et al 2013).…”

Ratnaningrum YWN, Indrioko S, Faridah E, Syahbudin A. 2018. Population structures and seasons affected flowering, pollination and reproductive outputs of sandalwood in Gunung Sewu, Java, Indonesia. Nusantara Bioscience 10: 12-26. Sandalwood was the origin to the south-eastern islands of Indonesia, but is recently occurred as new landraces in Gunung Sewu Geopark, Java, Indonesia. This study compared flowering and pollination, and their effect on reproductive outputs, among sandalwood populations in Gunung Sewu, during the dry and rainy season of 2016 flowering period. Flowering and pollination rate differed significantly between seasons but were similar among sites. Oppositely, reproductive outputs differed significantly among sites, but were similar between seasons. The rainy season produced more flowers and pollination. Pollination was less correlated to flowers abundance, but more affected by population size. The higher and cooler population visited more by Dipterans (31.8% to 32.6%) and Hymenopterans (28.2% to 30%), while the warmer, lower sites dominated by Lepidopterans (37.2% to 43%) and Dipterans (32.9% to 38.2%). Higher population received fewer visits, but more visitors diversity (28 families). In contrast, lower sites received more visits, but with less diversity (20 families). Most insect families were considered â€œRareâ€ and â€œOccasionalâ€. However, pooled altogether, the whole families of Lepidopterans and Dipterans considered â€œFrequentâ€ and â€œEffectiveâ€. The Hymenopterans considered â€œFrequentâ€ and â€œEffectiveâ€ at Nglanggeran and Wanagama. The Cicadellidae of Coleopterans, along with arachnids and grasshoppers, were considered robbers. All of the agents were diurnal. However, the time of activity was varied. Rainy season gained more flowers and visits, but in contrast, resulted in fewer fruits at all sites. Both flowers abundance and pollination were negatively correlated to the reproductive parameters. Populations might gain more flowers and visits, but the reproductive outputs were significantly lower. Particularly in the clonalized and lower heterozygosity populations, more flowers increased geitonogamy which may lead to inbreeding depression.

“…Fenologi pembungaan, yang meliputi inisiasi, frekuensi, dan durasi pembungaan (Owens et al 1991), merupakan mekanisme alami untuk beradaptasi secara ekologis maupun fisiologis terhadap kondisi lingkungan (Barrett et al 2006;Richardson et al 2013). Variasi fenologi pembungaan berkontribusi pada struktur populasi (Tsaliki & Diekmann 2011;Richardson et al 2013), perilaku agen penyerbuk (Herlihy & Eckert 2005;Arroyo et al 2006), aliran gen (Alizoti et al 2010;Yang et al 2013;Park et al 2014), serta karakter reproduksi (Collin & Shykoff 2003;Alizoti et al 2010;Weber & Kolb 2013;Agullo et al 2015).…”
