Abstract Argylia radiata is an herbaceous perennial plant native to northern Chile and a representative species of the “Blooming Desert”. Due its showy flowers other morphological characteristics, A. has great ornamental potential. In earlier work, deep morpho-anatomical description was made, but micropropagation protocols, which could be used for commercial purposes, are not known. Previous as...

Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...

In order to improve the shoot proliferation rate of ‘Dwarf Cavendish’ banana shoot tip cultures, polyethylene glycol (PEG6000) was employed at concentrations of 2, 4, and 6% (w/v). The medium without PEG was considered as negative control. An increasing of shoot proliferation was achieved in MS medium containing 2% PEG. Furthermore, application of 2% PEG significantly increased the shoot dry we...

An experiment was carried out in a roadside agroforestry system established along farm roadsides of Bangladesh Agricultural University, Mymensingh, to investigate the effects of pruning and pollarding on shoot development in Sesbania grandiflora L. Six treatment combinations with the stock plants studied during the period from August to September, 2007. The results revealed that the different p...

A rapid and efficient protocol was developed for inducing direct organogenesis using shoot tip explants of Vernonia cinerea L. Shoot tip explants were cultured on MS medium supplemented with different concentrations of BAP (2.22 to 22.20 μM/l) and KN (2.42 to 23.20 μM/l) for direct shoot induction. The frequency of multiple shoot induction and proliferation increased with increasing concentrati...

This paper describes attempts to localize the site of perception of low temperatures (0-10 degrees C) during thermoinduction in Thlaspi arvense L. Reproductive development (stem elongation and flower formation) was observed when shoots were cooled to 4 degrees C for 4 weeks and then returned to 21 degrees C while maintaining the roots constant 21 degrees C. However, chilling the roots was ineff...
