Study On Seed Morphometry Of Some Threatened Western Himalayan Orchids, Jagdeep Verma, Kusum Sharma, Kranti Thakur, Jaspreet Kaur Sembi, Suraj Prakash Vij Jan 2014

Study On Seed Morphometry Of Some Threatened Western Himalayan Orchids, Jagdeep Verma, Kusum Sharma, Kranti Thakur, Jaspreet Kaur Sembi, Suraj Prakash Vij

Turkish Journal of Botany

Physical seed characteristics of 32 threatened Western Himalayan orchids belonging to 23 genera of 3 subfamilies were studied using light and scanning electron microscopy. The species showed remarkable seed shape variations (fusiform, spathulate, ovoid, filiform) irrespective of their taxonomic position. Epiphytes produced relatively small-sized seeds compared to their terrestrial, lithophytic, or mycoheterotrophic counterparts. Seeds were truncated (length/width < 6.0) in 27 species, and were mostly elongated (length/width = 19.957 ± 1.459) in the orchidoid species Goodyera biflora (Lindl.) Hook.f. The number or size of testa cells was found fairly consistent at the genus level, and their walls were straight, sinuous, or undulate. Periclinal walls possessed vertical or oblique ornamentation in 6 species, which is of taxonomic implication. Embryos were rather tiny and most of the seed space (even >90% in 7 species) was occupied by air. The highest seed to embryo volume ratio was recorded in terrestrial Liparis odorata (Willd.) Lindl. and the lowest in epiphytic Rhynchostylis retusa (L.) Blume, both of which are members of the advanced Epidendroideae. Seed characteristics …

Plasticity And Within Plant Sex-Ratio Variation In Monoecious Emex Spinosa, Regina Berjano, Montserrat Arista, María Talavera, María Jesús Ariza, Pedro Luis Ortiz

Turkish Journal of Botany

Understanding how phenotype trait expression varies at different levels of biological organization is crucial to understanding the fundamental ecological, evolutionary, and developmental issues that contribute to adaptive plasticity. This is particularly important in plants because of their modular organization. Here, we study plasticity in flower production in response to light intensity at 3 levels of biological organization (between populations, among individuals, and within individuals) in Emex spinosa (L.) Compd., a Mediterranean amphicarpic annual. Plants exposed to high light intensity grew faster and produced more flowers than plants at low light intensity. Female flower production was the most labile trait. Within …
