Carnation is one of the most important species on the worldwide market of cut flowers. Commercial carnation cultivars are vegetatively propagated from terminal stem cuttings that undergo a rooting and acclimation process. For some of the new cultivars that are being developed by ornamental breeders, poor adventitious root (AR) formation limits its commercial scaling-up, due to a significant inc...

AIastradTechniques for vegetative propagation of 10-year-old blue SP.'Uce (Picea pungens EngeJm.) by stem cuttings were investigated. Month of collection of the cuttings and application of rooting hormones were examined. In addition, cutting position, cutting length and caliper were examined in relation to rooting response. December was the best collection date for rooting and root production. ...

We present in this paper a new direction finding algorithm for non circular sources that is based on polynomial rooting. Due to the non circularity characteristics of the impinging sources, the proposed method is able to handle more sources than sensors. By using a polynomial rooting instead of a searching technique the method is limited to linear uniformly spaced arrays. However, polynomial ro...

Studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as Henna. The purpose of this study is to determine an appropriate concentration of Naphthalene Acetic Acid (NAA), Indole Butyric Acid (IBA) and salicylic acid (SA) on Rooting of Henna. Present study showed that there was a great variation in most of the measured characters at P<...

The relationships between rooting potential with endogenous phenolic compounds, nitrogen and soluble carbohydrates of cuttings for five olive cultivars (‘Rowghani’, ‘Dusti’, ‘Tokhmekabki’, ‘Konservalia’ and ‘Amigdalolia’) were investigated. Extracts of the leaves and the base of the cuttings were used for analysis of biochemical compounds. Results showed that there were significant differences ...

Scrutinizing of different aspects in vegetative propagation of Iranian J. communis L. is of prime importance in order to prevent extinction of such valuable conifer. In this research, the effects of different seasons, gender, different chemical compounds (IBA, PBZ, putrescine and sodium nitroprusside) and three strains of Agrobacterium rhizogenes on ex-vitro rooting c...

Differences in rooting ability of birch (Betula pubescens J.F. Ehrh.) cuttings were observed as a result of differences in genotype and physiology of the stock plants. The uniformity in response among cuttings from micropropagated plants compared with cuttings from seed plants confirmed the advantage of using micropropagated plants to study environmental effects. Shoot morphology of the seed st...

Stabilized shoot cultures initiated from crown material of six adult Quercus robur L. trees and from basal epicormic shoots of a Quercus rubra L. tree showed good in vitro rooting capacity. An initial five-day dark period generally improved the rooting response but was detrimental to plantlet quality. There were clonal differences in rooting capacity. The concentration and exposure time of the ...
