This study was carried out to determine the effects of genotype and media on haploid plant formation 12 pepper genotypes (Capsicum annuum L.) via in vitro anther culture. The buds were cultured 2 different (O1 O2) and, results revealed that had development anthers, embryo plantlet initiation. When developmental status is examined, lowest value obtained from SU-31 with 2.47%, while cv. Flinta F1...

Albinism in plants is characterized by partial or complete loss of chlorophyll pigments and incomplete differentiation chloroplast membranes. This a very common problem encountered interspecific crosses tissue culture experiments including anther generation doubled haploids. impairs photosynthesis the eventually die at young stage without reaching maturity. Environmental conditions such as ligh...

BACKGROUND AND AIMS Anther appendages play diverse roles in anther dehiscence and pollen dispersal. This study aims to explore the pollen-dispensing mechanism triggered by special anther appendages in Incarvillea arguta. METHODS Field studies were conducted to record floral characteristics, pollinator visitations, and flower-pollinator interactions. Measurements of flowers and pollinators wer...

Apposite development of anther and its dehiscence are important for the reproductive success of the flowering plants. Recently, bHLH142, a bHLH transcription factor encoding gene of rice has been found to show anther-specific expression and mutant analyses suggest its functions in regulating tapetum differentiation and degeneration during anther development. However, our study on protein level ...

The anther, pollen and ovule development in Achillea tenuifolia were studied with a bright field microscopy. Results showed that the anther is of tetrasporangiate type and the anther wall is composed by four layers: an epidermis, an endothecium, one middle layer and a tapetum layer. Tapetum is of secretory type and its cells showed polyploidy. Pollen tetrads were tetrahedral, microspores were v...

In that report solution to incompressible Navier Stokes equations in non dimensional form will be presented. Standard fundamental methods: SIMPLE, SIMPLER (SIMPLE Revised) and Vorticity-Stream function approach are compared and results of them are analyzed for standard CFD test case Drived Cavity flow. Different aspect ratios of cavity and different Reynolds numbers are studied.
