in this research, the effect of irrigation duration on growth characteristics of thomson navel orange grafted on three rootstocks was evaluated in complete randomized block design in iran citrus research institute. factors included rootstock in three levels (poncirus (poncitus trifoliate), citrange (citrus sinensis  poncitus trifoliata) and sour orange (citrus aurantium)) duration of irrigatio...

In plants, successful reproduction requires the proper timing of flowering under changing environmental conditions. Arabidopsis FLOWERING LOCUS T (FT), which encodes a proposed phloem-mobile florigen, has a close homologue, TWIN SISTER OF FT (TSF). During the vegetative phase, TSF shows high levels of expression in the hypocotyl before FT induction, but the tsf mutation does not have an apparen...

Reciprocal cleft and pistillate floral bud grafts were made between parthenocarpic ;Fertilla' and nonparthenocarpic ;MSU 713-5' cucumber (Cucumis sativus L.) lines to localize the site for stimulation of parthenocarpic fruit set. No fruit set on ;MSU 713-5' controls, scion grafted to ;Fertilla,' or rootstock with ;Fertilla' as the scion. ;Fertilla' controls, rootstock, and scions all produced p...

Bemisia tabaci is one of the most devastating pests in tomato greenhouse production. Insecticide resistance management for B. tabaci requires a novel approach that maximizes non-chemical methods for pest control. The aim of this study was to test the effects of rootstocks on B. tabaci populations in hydroponically grown tomato plants. In order to contribute to the better understanding of the me...

indian ber (ziziphus mauritiana) has growing type as grape and is inclined to horizental and down ward growth. if it is not trained appropriately, it would grow into very bushy with thiny shoots. hence, such trees have short lives, and are liable to pests and diseases with low yield. fruit harvesting is also difficult in bushy trees. therefore, proper pruning and training of young trees is esse...

hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...

The xylem-limited bacterium Xylella fastidiosa (Xf) causes Pierce's disease (PD), an important disease of grapevine, Vitis vinifera L. Grapevine rootstocks were developed to provide increased resistance to root disease, but rootstock effects on cane and vine diseases remain unclear. Grapevines that consisted of Cabernet Sauvignon or Chardonnay grafted to 13 different rootstocks were inoculated ...

'Jones Hybrid' hickory is an accession in the National Collection of Genetic Resources for Pecans and Hickories for which information about origin, identity and characteristics is very incomplete. Phenotypic and genetic profiles, when examined in the context of historic literature, provide evidence that the accession in question is 'Siers' a cultivar of Carya × laneyi (an interspecific hybrid b...
