“…Therefore, it is highly important to understand the ecological behavior of these medicinal plants, e.g., their flowering phenology, to understand their reproductive success (Liu et al 2021). It is important to understand reproductive behavior of plants to prioritize the conservation efforts as well as comprehend the effect of climate change on plant's reproductive traits (Tandon et al 2020).…”

Background: Traditional knowledge plays an important role in the conservation of floral diversity and is often used for the treatment of numerous diseases in local medicinal systems. Diverse cultural groups in the Himalayan regions have their own local indigenous healthcare systems, with medicinal plant applications that differ depending on geography and ecology. Therefore, it is important to understand plant ecological behavior for prioritizing conservation efforts and comprehending the impact of climate change on plant phenological traits. Methods: Ethnopharmacological data was collected through interviews and group discussions using semistructured and close-ended questionnaires from different ethnic groups i.e., Gujjar, Bakarwal, and Kashmiri. The data was subjected to hierarchical cluster analysis and ordination techniques (Principal Component Analysis) using multivariate software.Results: The present investigation documented a total of 32 plant species belonging to 31 genera in 23 families.Across the 23 families, the distribution of species was unequal, half of the species belonged to just 6 families (Asteraceae, Berberidaceae, Lamiaceae, Ranunculaceae, Solanaceae and Amaranthaceae) while the remaining half belonged to 17 families. Amongst the parts of plants, roots were the most utilized plant part with 25% of usage followed by whole plant (22%). Gastro-intestinal disorders were treated with most species (18%), followed by pulmonary infections (13%). A heat map showed two distinctly separated clusters based on the degree of intensity of flowering timing of the flora and month. Based on the conservation assessment, out 19% of all species observed fell in the Critically Endangered category of IUCN, followed by 6% in the Vulnerable category.Conclusions: This study provides the ethnopharmacological and ecological scope of the plants of the Kashmir in the northern Himalaya. There is need to develop strategies to conserve and sustainably harvest these plants in order to maintain their long-term benefits in the medicinal field.

“…The accomplishment of the phenomenon is greatly influenced by two components viz., intrinsic reproductive biology of the organism and the interactive niche in which they survive. The environment in which the plants grow has a major impact as it is decisive in every step of reproduction in plants, due to the fact that the plants are immobile [1]. Therefore, the reproductive success of plant can be constrained by any attributes in the ecosystem where they grow.…”

Plant Reproductive Ecology - Recent Advances

Plants display an assorted collection of reproductive tactics that eventually play a crucial role in perpetuation of species. Plant reproductive ecology is principally concerned with the adaptive implications of the plant in their vicinity, disparity in qualities allied with pollination, seed dispersal, and seedling establishment. The success in reproduction in most flowering plants depends on ecological interactions with pollinators and seed dispersal agents. Modern tactics in reproductive ecology can integrate proper surveys, advanced pollination studies, interaction between flower and pollinators and clear assessments of population genetic structure, which can provide new opportunities for plant reproductive biology. Alfalfa is an important forage legume and known as “Queen of forages” due to its worldwide adaptability, high yield potential and quality. Alfalfa produces seeds which are primarily used for forage production. It is a gift to livestock industry including dairy, beef, horses, and sheep for grazing, silage, hay etc. Alfalfa is also a medicinal herb with antioxidant, antidiabetic, anti-inflammatory, neuroprotective and cardioprotective properties, utilized for treatment of arthritis, kidney problems. The seeds are exploited in alfalfa sprout industry. The current chapter highlights the reproductive biology of alfalfa from flower development to seed production and its advances.

“…Sexual reproduction in angiosperms (Tandon et al, 2020 ) occurs through some main steps, the landing and adhesion of the pollen on the receptive stigma of the flower, the growth of the pollen tube with penetration of the stigma, and growth inside the pistil to conduct the sperm cells up to the eggs for fertilization. Pollen is enveloped by the exine wall in which plants with entomophilous pollination are covered by a layer of pollenkitt including lipids, carotenoids, flavonoids, proteins, and sugars (Pacini and Hesse, 2005 ) that make up the interfacial layer for interactions with biotic and abiotic environment, and further interactions are controlled by other organic compounds on the exine and the underlying wall (intine) (Hiscock and Allen, 2008 ).…”

Nanoporous silica gel can compete with the flower stigma in germinating and attracting pollen tubes

To find nanoporous substrates with hydrodynamic properties useful for pollen hydration and germination, we used the glassy Silica gel and Vycor scales and pollen with different morphological and physiological traits, that of Crocus vernus, and that of Narcissus poeticus. For in vitro tests, the scales were spread on microscope slides, hand pollinated, and incubated. Pollen germination was evaluated with the stereomicroscope and the tube growth was explored with scanning electron microscopy (SEM). The in vivo tests were carried out by sprinkling the stigmas of the Crocus plants with Silica gel scales and immediately after having pollinated them by hand, the plants were incubated. Three hours later, the stigmas were removed and treated for observation with SEM. In vitro the pollen of both species germinated on Silica gel with percentages similar to those of the in vivo and in vitro controls, accumulating fibrillary material at the interface. The tubes grew perpendicular to the surface of the scales, trying to penetrate the scales to the point of flattening with the apex. On Crocus stigmas sprinkled with Silica gel scales, pollen developed tubes that grew to the scales rather than penetrating the papillae. The results underline the close interaction of pollen with nanoporous artificial material, so much so that its pollen tubes are attracted to the Silica scales more than to the stigma papillae that arises from a mechanism of natural selection.
