Photosynthetic Gas Exchange, Chlorophyll Fluorescence, Antioxidant Enzymes, And Growth Responses Of Jatropha Curcas During Soil Flooding, Krishan Kumar Verma, Munna Singh, Ramwant Kumar Gupta, Chhedi Lal Verma
Turkish Journal of Botany
The response of chlorophyll fluorescence, photosynthetic CO_2 assimilation (PN), stomatal conductance (gs), electrolyte leakage, and transpiration (E) was observed in Jatropha curcas seedlings subjected to soil flooding. A strong reduction in growth, leaf-area expansion (64%), and stomatal conductance (45%) impaired photosynthetic CO_2 assimilation (66%), which eventually reduced biomass yield. The ratio between variable-to-initial chlorophyll fluorescence (Fv/Fo) and the maximum quantum yield efficiency of the photosystem II (Fv/Fm) was used to explore damage associated with the functioning of the photosynthetic apparatus. A strong, non-linear correlation between physiological parameters and soil flooding duration was found. Our study primarily revealed consequences of epigenetics, …

Cytological Evidence For Gametophytic Self-Incompatibility In The Genus Veronica, Romain Scalone, Dirk Albach
Cytological Evidence For Gametophytic Self-Incompatibility In The Genus Veronica, Romain Scalone, Dirk Albach
Turkish Journal of Botany
The self-incompatibility (SI) of 3 Middle East Veronica species (V. filiformis, V. gentianoides, V. teucrium) is studied, for the first time, by pollination and pollen tube growth experiments. Cytological observations of the self-pollen tubes within the pistils permit a conclusion about the presence of a gametophytic SI system in the first 2 species. The investigated population of the third is self-compatible and confirms the facultative trait of its self-sterility. The presence of a gametophytic SI system in 2 of them suggests the putative conservation of this SI system within the genus Veronica (Plantaginaceae) and could be related to the well-known …

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 …

Chilling Tolerance Of Cicer Arietinum Lines Evaluated By Photosystem Ii And Antioxidant Activities, Özlem Turan, Yasemi̇n Ekmekçi̇
Turkish Journal of Botany
Two chickpea (Cicer arietinum L.) lines (AKN 87 and AKN 290) that have different chilling susceptibilities were exposed to 2 chilling temperatures (4 and 2 °C), either cold-acclimated (10 °C) or nonacclimated (25 °C), in order to understand and compare physiological and biochemical changes at the vegetative stage. Chilling temperatures resulted in reduced growth parameters, particularly in cold-acclimated lines, whereas nonacclimated plants exhibited the lowest water contents. Cold acclimation treatment led to protective changes of increased flavonoid, proline, and antioxidant enzyme activities, mostly superoxide dismutase (SOD) and ascorbate peroxidase (APX), in the lines. However, the 10 °C treatment did not …
