Pollen Banks and Genetic Resources

Collecting pollen for genetic resources conservation 25

Pollen grains are the mature male (haploid) gametophyte of higher plants. These tiny organs (10-100 IJ.m in diameter) develop in the anthers (Stanley and Linskens, 1974). When the flower opens the anthers become exposed to the environment and dehydration triggers a mechanism for release of the pollen. In the process, the pollen also dehydrates. Though the pollen of most species can withstand dr...

Pomegranate: Biodiversity and genetic resources, a review

Pomegranate (Punica granatum L.) is a multipurpose plant that is important as nutrition, medical, horticulture, landscape and environment. The plant has been cultivated since old Iran and Egypt which is mentioned in Bible and Quran. Origin of the plant is Iran and some neighbour countries, although it is cultivated in many countries, now a day. Botanically, it is classified in Punicaceae and ha...

The Impact of Seed Polymorphism of Plant Genetic Resources on the Collection Strategy of Gene Banks

Seed morphs of Calendula officinalis were investigated in order to examine the genetic variability which correlates with seed polymorphism and its impact on collection strategy of gene banks. The basic parameters to get the evidence were obtained from morphological data, karyotype analysis, electrophoretic pattern of seed proteins as well as nucleic acid analysis. Seven seed morphs were observe...

Multi-Component Efficiency with Shared Resources in Commercial Banks

Genetic variability and diversity of the main resources of lily assessed via phenotypic characters, pollen morphology, and ISSR markers.

Lily (Lilium spp), which belongs to Lilium, is one kind of monocotyledon. As a perennial ornamental plant with extremely high esthetic, edible, and medicinal value, lily has gained much favor due to its mostly showy flowers of various colors and elegant shape. In this research, we studied experimental materials in a sample of 49 individuals including 40 cultivars, nine species of wild lily, and...
