“…Pollinator visitation was found to vary in response to weather conditions, as did the magnitude of reproductive assurance (Ruan et al, 2009b). Moreover, pollinator failure, or (1 -fruit set of emasculated flowers/fruit set of hand-outcrossed flowers) (Kalisz et al, 2004) and selfing rate were positively correlated, providing further evidence for delayed selfing as a BOBW mating system (Ruan et al, 2009a).…”

“…In Kosteletzkya virginica, experimental emasculation of flowers demonstrated that progressive stigma curvature in unpollinated flowers confers delayed selfing (Ruan et al, 2009b). Large, showy flowers and nectar appear to be adapted for pollinator visitation, and inbreeding depression is substantial at 0.5 (Ruan et al, 2009a(Ruan et al, , 2009b. The selfing mechanism is highly effective, with autofertility estimated at 0.99 (Ruan et al, 2008).…”

In a series of seminal papers, David G. Lloyd (1979;Lloyd and Schoen, 1992) provided new insight into plant mating-system evolution by recognizing that the selective consequences of selfand cross-pollination and fertilization depend on the specifics of how and when they occur. In phenotypic models, Lloyd showed that the conditions that select for self-fertilization (selfing) facilitated by pollinators differ from those for selfing that occurs autonomously. Further, the selective consequences of autonomous selfing were shown to depend on its timing in anthesis in relation to cross-fertilization (outcrossing). The theory predicts that selfing that occurs after opportunities for outcrossing have passed (delayed selfing) should be selected under the broadest range of conditions.In general, selection of selfing is expected to be opposed by inbreeding depression, the reduced fitness of selfed progeny that results primarily from the expression of deleterious recessive alleles Charlesworth, 1987, Charlesworth andWillis, 2009). Counteracting the cost of inbreeding depression is the 50% genetic transmission advantage of selfing, which occurs because INVITED SPECIAL ARTICLE The best of both worlds? A review of delayed selfing in flowering plantsCarol Goodwillie 1,3 and Jennifer J. Weber PREMISE OF STUDY:In a seminal body of theory, Lloyd showed that the fitness consequences of selfing will depend on its timing in anthesis. Selfing that occurs after opportunities for outcrossing or pollen dispersal can provide reproductive assurance when pollinators are limited and is expected to incur little cost, even when inbreeding depression is high. As a result, delayed selfing is often interpreted as a "best-of-both-worlds" mating system that combines the advantages of selfing and outcrossing. METHODS:We surveyed 65 empirical studies of delayed selfing, recording floral mechanisms and examining information on inbreeding depression, autofertility, and other parameters to test the support for delayed selfing as a best-of-both-worlds strategy.KEY RESULTS: Phylogenetic distribution of the diverse floral mechanisms suggests that some basic floral structures may predispose plant taxa to evolve delayed selfing. Delayed selfing appears to serve as a best-of-both-worlds strategy in some but not all species. While the capacity for autonomous selfing is often high, it is lower, in some cases, than in related species with earlier modes of selfing. In other delayed-selfers, low inbreeding depression and reduced investment in corollas and pollen suggest limited benefits from outcrossing.CONCLUSIONS: Despite a growing literature on the subject, experimental evidence for delayed selfing is limited and major gaps in knowledge remain, particularly with respect to the stability of delayed selfing and the conditions that may favor transitions between delayed and earlier selfing. Finally, we suggest a potential role of delayed selfing in facilitating transitions from self-incompatibility to selfing.

“…Though few of these species are managed for their pollination services, they are nonetheless essential to sustaining the fruit and seed set of the majority of the regions' flowering plants (Axelrod 1960;Klein et al 2007;Ollerton et al 2011). The absence of these species has been associated with, among other things, substantial shifts in the structure of plant-pollinator networks (Kaiser-Bunbury et al 2010;Lever et al 2014), genetic isolation between plant populations (Aguilar et al 2006;Tepedino et al 2014), limits to geographic ranges of plants (eg Moeller et al 2012), the loss of endangered plant species (eg Chi and Molano-Flores 2015), and changes in reproductive strategies for some flowering plants (eg Ruan et al 2009). In agricultural habitats, even in the presence of managed honey bee colonies, native bees are major contributors to the pollination of crops (eg Mandelik et al 2012;Rader et al 2013), and their absence can make a significant difference in fruit set (Garibaldi et al 2013).…”

Recent analyses suggesting that certain populations of bees may be declining have led to a variety of conservation efforts, many of which rely on public support and participation. However, little is known about the public's knowledge of bee diversity. We carried out a survey to measure public understanding of bee diversity and found that although 99% of respondents believed that bees are critical or important, only 14% were able to guess within 1000 the actual number of bee species in the US. Furthermore, when reviewing a selection of photographs depicting various insects, many respondents were unable to discern bees from non-bees. Our findings show that even as scientific research on bees has rapidly expanded, the public remains largely uninformed on the subject, especially with regard to the wealth of bee diversity in the US. In light of the fact that conservation efforts require substantial public support, any programs aimed at stopping or mitigating bee population declines will need to include outreach and education measures.

“…It is reported by United Nations Educational Scientific and Cultural Organization that the saline soil take up ten precents of the earth. Reduction in yields due to secondary salinization from irrigation, limits to supplies of freshwater, and the growing need in many developing nations for agricultural output from semi-arid and arid maritime regions fed by brackish aquifers have all stimulated widespread efforts to improve salt tolerance in traditional crops and to identify potential new crop plants among wild species native to saline areas [1][2][3].…”

Preparation, composition, structure and properties of the Kosteletzkya virginica bast fiber

In this paper, the bast of the Kosteletzkya virginica are degummed and separated into fine fibers, the chemical composition, morphology, microstructure and mechanical properties of the Kosteletzkya virginica bast fibers are characterized by means of SEM, ART-FTIR, DSC-TGA, XRD and Instron tensile tester. The results show that the surface of the Kosteletzkya virginica bast fibers is smooth, and there are many visible grooves along the vertical section. Typical cellulose I in the Kosteletzkya virginica bast fibers is confirmed by FTIR and XRD analysis. The crystallinity of the Kosteletzkya virginica bast fibers is higher than that of the cotton fibers and lower than that of the castor-oil plant bast fibers. The beginning and maximum decomposition temperature of the Kosteletzkya virginica bast fibers are 252 and 347 o C respectively, which indicate that the Kosteletzkya virginica bast fibers have an appropriate thermal stability. The Kosteletzkya virginica bast fibers have a better mechanical properties and excellent hygroscopicity. All the results show that the Kosteletzkya virginica bast fiber is one of an ideal candidate for the new textile material.
