Current study was set up to determine the response of 12 Iranian winter diploid barley (Hordeum vulgare L.) cultivars to anther culture on solid FHG induction medium supplemented with 90 mg/l sucrose, 2 mg/l 2,4-D and 0.1 mg/l kinetin. For cold pretreatment each selected spike was kept in a refrigerator at 4 C for 14 days. The experimental design consisted of a completely randomized design (CRD...

The purpose of this work was to study the effects of ultraviolet (UV) irradiation on denucleation of eggs and investigate the heat-shock conditions for diploidization for induction of androgenesis in muskellunge, Esox masquinongy. Several egg incubation media, including saline, Ringer's solution, and Ringer's solution supplemented with bovine serum albumin (BSA), were found suitable to maintain...

irst case of haploidy in higher plants was reported in Datura stramonium T $ : ~ ~ ~ ~ ~ ~ ~ et al. 1922). Subsequently, haploid sporophytes have been discovered in many plant species; STADLER and RANDOLPH first reported haploidy in maize (1929 unpublished, cited by RANDOLPH 1932). Numerous investigations have been conducted on the occurrence of spontaneous and induced haploids in a number of s...

Steroidogenesis plays a key role in the development and maintenance of male reproductive function and fertility. The objective of the present study was to investigate the effect of Carica papaya seed extract on steroidogenesis. The reduced cholesterol levels indicate decreased mobilization towards androgenesis which leads to decreased steroidogenesis and thereby inhibition of spermatogenesis in...

Capsicum (Capsicum annuum L.), commonly known as pepper, sweet pepper or bell pepper, belongs to the family Solanaceae and is one of the most important vegetable crops in the world. This indispensable item of kitchen occupying an important place in Indian diet is consumed daily in one or the other form as a condiment and spice, vegetable, adding colour, flavour, pungency and piquancy to various...
