“…Although there are a number of reports of seed predation in Hedysareae such as Onobrychis (Jermy & Szentesi 2003;Delobel & Delobel 2006), such studies are rather limited in the case of the Hedysarum genus. There are some reports in the scientific literature about predators of Hedysarum species; for example, Acanthoscelides beetle (the largest in the beetle subfamily Bruchinae) as a seed predator of Hedysarum boreale (Cane et al 2013) and Paleoacanthoscelides gilvus as a seed predator of H. spinosissimum, H. coronarium and H. flexuosum (Hoffmann 1945;Delobel & Delobel 2006). For the first time, we observed Bruchidius koenigi as the seed predator of H. criniferum.…”

“…However, it is normal in many cases that some and not all of a seed crop is consumed by seed predators (Auld ; Szentesi ; Cane et al . ).There is also sometimes evidence indicating that the impact of seed predators on plant populations has been slight (Andersen ; Myers & Bazely ).This is almost the same for our case of H. criniferum , for which there are still enough seeds for normal regeneration, even though 27% of the seeds are consumed by seed predators.…”

Antagonists and mutualists both play important roles in a plant's reproductive fitness. In the present study, seed predator and pollinator effects were studied simultaneously in a patchily distributed legume, Hedysarum criniferum, in its natural habitat in the Irano‐Turanian region. This experiment examined whether a relationship existed between seed predator and pollinator effects on H. criniferum seed production, and the degree to which each of them impacts the plant's seed survival. To achieve this goal, the effects of seed predators and pollinators in an exclosure were separately and simultaneously evaluated, using a 2 × 2 factorial design, with 16–20 plants per treatment (n = 70) in four replications. The results show that the pollinators caused a 40‐fold increment in loments, a 59.3‐fold greater production in seeds and a 14‐fold increment in gross fecundity compared with their absence. Moreover, the seed predators infected on average 23% of the seeds. It was also observed that seed abortion, as well as the interaction of seed predator × pollinator effects on seed production, was insignificant. Despite the loss of some seeds caused by seed predators, the healthy seeds were sufficient to guarantee plant survival. Consequently, seed predators seem not to be the main factor in the patchy distribution of H. criniferum and, therefore, to develop plant habitats by seeds, it is more important to protect the pollinators than to devise any intervention to remove the predators. Bruchidius koenigi Schilsky and a description of its host plant are reported here for the first time from Iran.

“…Weeds were controlled primarily with cultivation and hand rouging. Harvested seed pods of D. ornata, D. searlsiae, and A. filipes were extensively damaged from feeding by seed beetles in 2013 (Cane et al, 2013). Damage was observed in 2014, but to a lesser degree than in 2013.…”

Increasing the supply of native wildflower seed is essential for restoring burned and degraded wildlands in the Intermountain West. Limitations to wildland seed collection necessitate development of effective cultural practices to improve reliability of seed production in agricultural fields. Irrigation trials were conducted over multiple years for three perennial species in the Fabaceae family [Dalea ornata (Douglas ex Hook.) Eaton & J. Wright, Dalea searlsiae (A. Gray) Barneby, and Astragalus filipes Torr. ex A. Gray]. Each of the three species was grown at the Oregon State University Malheur Experiment Station, Ontario, OR and received 0, 100, or 200 mm·year−1 of drip irrigation in four equal biweekly increments during bud formation and flowering. Seed yield responses to irrigation were evaluated by linear and quadratic regression against 1) applied water, 2) applied water plus spring precipitation, 3) applied water plus winter and spring precipitation, and 4) applied water plus fall, winter, and spring precipitation. In general, seed yields responded quadratically to irrigation. Adding fall, winter, and spring precipitation to applied water improved the accuracy of estimated water requirements for maximum seed production of D. ornata and D. searlsiae. For D. ornata, the highest yields averaged 396 kg·ha−1 and ranged from 146 to 545 kg·ha−1. Averaged over 6 years, seed yield of D. ornata was highest with applied water plus fall, winter, and spring precipitation totaling 393 mm. For D. searlsiae, the highest yields averaged 260 kg·ha−1 and ranged from 51 to 424 kg·ha−1. Averaged over 6 years, seed yield of D. searlsiae was highest with applied water plus fall, winter, and spring precipitation totaling 412 mm. Seed yields of A. filipes ranged from 7 to 110 kg·ha−1 depending on year and averaged 40 kg·ha1 over 6 years. Seed yields of A. filipes did not respond to irrigation in any of the 5 years of testing.

Reproductive biology, ecological life history/demography and genetic diversity of the megagenus Astragalus (Fabaceae, Papilionoideae)

et al. 2021

View full text Add to dashboard Cite

Astragalus is the largest genus of seed plants; however, information on its reproductive biology and life history is widely scattered in the literature. About 96% of the species are perennials and 4% annuals; many are rare endemics. Astragalus species are obligate or facultative outcrossers, and inbreeding depression is higher in self-compatible (SC) than in self-incompatible (SI) species. The most frequent pollinators are Bombus, Osmia and Anthophora. On average, 48% of ovules produce seeds, and 40% of flowers produce fruits. Seed/ovule and fruit/flower ratios are lower in SC than in SI species. Predispersal insect seed predation ranges from 0 to 93%, and major predators are Acanthoscelides, Bruchophagus and Tychius. Seeds have physical dormancy and typically form a seed bank. C 3 is the only photosynthetic pathway in the genus. Population growth may be cyclic or noncyclic, and genetic diversity of a taxon may or may not be related to size of geographic range.
