In gynodioecious plants, females are expected to produce more or better seeds than hermaphrodites in order to be maintained within the same population. Even though rarely measured, higher seed production can be achieved through differences in physiology. In this work, we measured sexual dimorphism in several physiological traits in the gynodioecious plant Geranium sylvaticum. Photosynthetic rate, stomatal conductance, transpiration rate, WUE and isotopic signatures were measured in plants growing in two habitats differing in light availability. Females have been reported to produce more seeds than hermaphrodites. However, we did not observe any significant difference in seed output between the sexes in these experimental populations. Similarly, the sexes did not differ in any physiological trait measured. Seed production was strongly limited by light availability. Likewise, differences between plants growing in full light versus low light were detected in most physiological parameters measured. Our results show that the sexes in G. sylvaticum do not show any evidence of sexual dimorphism in physiology, which concurred with a lack of sexual differences in seed output. ...

Absence of Sex Differential Plasticity to Light Availability during Seed Maturation in Geranium sylvaticum Varga, Sandra; Laaksonen, Ester; Siikamäki, Pirkko; Kytöviita, Minna-Maarit (Public Library of Science, 2015)Sex-differential plasticity (SDP) hypothesis suggests that since hermaphrodites gain fitness through both pollen and seed production they may have evolved a higher degree of plasticity in their reproductive strategy compared ...
Nectar sugar production across floral phases in the gynodioecious protandrous plant Geranium sylvaticum Varga, Sandra; Nuortila, Carolin; Kytöviita, Minna-Maarit (Public Library of Science, 2013)Many zoophilous plants attract their pollinators by offering nectar as a reward. In gynodioecious plants (i.e. populations are composed of female and hermaphrodite individuals) nectar production has been repeatedly reported ...
Kähkölä, Kristiina (2016)Lisääntymissysteemiltään gynodieekkisissa kasvipopulaatioissa on tavallisesti sukupuoleltaan kahdenlaisia yksilöitä, puhtaasti emikukkaisia kasveja sekä kaksineuvoisia kukkia tuottavia kasveja. Nämä eri sukupuolet eroavat ...
Elzinga, Jelmer Anne; Varga, Sandra (Elsevier; Urban und Fischer Verlag, 2017)In gynodioecious plants females need a reproductive advantage over hermaphrodites to be maintained in the same population. Generally, three main proximate causes for a female advantage are considered: inbreeding avoidance, ...
