The present study reports the inflorescence ontogeny and morphology in tribe Fabeae (Fabaceae) addressing the evolutionary trends of selected inflorescence features in clade Lathyrus–Pisum–Vavilovia. In all three mentioned genera, the whole inflorescence in annual taxa comprises an open shoot bearing frondose leaves subtended by simple racemes. This shoot exhibits a pendulum symmetry which results...
Detailed studies on the distribution, structure, and secretion activity of floral glands are important to understand the relationship of flowers with oil-collecting bees in Malpighiaceae. Here, we characterised the floral biology and the glands in sepals, petals and connective tissues of Diplopterys pubipetala. The data on the floral biology were obtained under field conditions. The samples from functional...
Bromeliaceae is a Neotropical family that evolved ecological key innovations in association with extensive adaptive radiation. Its species present a variety of different mating system strategies varying within and among species, within genera and subfamilies. Also, species with a wide geographical range can display large variation in mating system, reproductive success and genetic diversity. Here...
Termites, herbivores and fire are recognized as major guilds that structure woody plant communities in African savanna and woodland ecosystems. An understanding of their interaction is crucial to design appropriate management regimes. The aim of this study was to evaluate the long–term impacts of herbivore, fire and termite activities on regeneration of trees. Permanent experimental quadrats were...
Phytolith formation in plants is commonly thought to be influenced by variations in temperature, precipitation and other environmental factors. The objective of this study is to test how variations in different climatic and edaphic factors i.e., temperature, rainfall, actual evapotranspiration (AET), potential evapotranspiration (PET), moisture index (MI) and soil pH along a tropical–temperate elevation...
Grewia asiatica L., an Asian shrub, is indigenous to India. Despite its immense importance in the Ayurvedic and traditional systems of medicine scientific and commercial exploration has been neglected. In this direction, we undertook systematic studies to understand the sexual system, breeding behaviour and reproductive phenology deployed by the species. Our results suggest that the species practices...
Ziziphus comprises important fruit trees that inhabit arid environments of tropical and subtropical regions of the world and are able to adapt to drought and salt stress. Species of this genus are characterized by synchronous protandrous dichogamy and self-incompatibility; however, reduced seed set after hand self-pollination indicates that self-fertilization is possible and that it causes a strong...
