Photoperiodism and vernalisation

When we look at the flowering plants around us, we notice that the flowers of these plants vary greatly in their appearance, structure, and arrangement on the branches. The mode of arrangement of flowers on the axis is termed an inflorescence. The pattern in which the flowers develop serves as the basis for the Classification […]

The vast majority of rose species are native to Asia, with a few exceptions from North America, Europe, and northwest Africa. Roses from around the world often hybridise, resulting in varieties that overlap the parental forms and make distinguishing between fundamental species difficult. Fewer than ten species, largely from Asia, mated and eventually produced many

A phylogenetic trend between two forms of gynoecia within Apiales may be of interest. In spite of the lack of morphological limitations (Weberling 1989; Erbar and Leins 1996, 2004; Leins and Erbar 2004), it is uncertain if the state found in Pittosporaceae is ancestral within Apiales. Stevens (2009) proposes that Pittosporaceae floral form is derived

We consider flowers the eye-catching, attractive, bright and fragrant structures of plants. But if we look at it from a biological perspective, flowers are the major reproductive part of plants. Not only reproductive, but it is also a source of food for other organisms.   Complete or incomplete flowers A complete flower comprises stamen (male), pistil

Amensalism is a sort of biological interaction between two organisms or species in which one is neither helped nor harmed, and the other is destroyed or inhibited. It’s a (0,-) interaction type. ‘0’ denotes no effect, whereas ‘-‘ denotes a negative effect. In general, it isn’t seen as a significant interaction because it is unintentional
