In this article we will discuss about the methods and significance of pollen storage in plants. Systematic research on pollen storage started at the end of the 19th century. There is large number of crop species, including vegetables, fibre and fruit crops, forage and cereals, for which pollen storage strategies are desirable. Genetic conservation through pollen storage is desirable for [...]
In this article we will discuss about:- 1. Distribution of Sporopollenin 2. Chemistry of Sporopollenin 3. Production and Deposition 4. Functions. Distribution of Sporopollenin: It was first observed and named as "sporonin" by John (1814) and latter characterized by Berzelius (1830). Fossil green algae dating back to Devonian period have been shown to contain sporopollenin. The oldest sporopolleninous acritarchs occur [...]
In this article we will discuss about the tests that have proven to determine the viability and vigour of pollen after storage in plants. I. Test for Pollen Viability: An assessment of pollen viability is imperative factor in the study of reproductive biology, pollen storage and hybridization. Thus there must be a quick and dependable method to determine the viability [...]
