The influence of two carbon sources, sorbitol and sucrose on In vitro shoot proliferation and rooting of peach rootstock GF 677 was compared at 15, 30, 45 and 60 g l concentrations. The highest number of shoots per proliferated explant, usable shoots and shoots having maximum fresh weight were obtained on sorbitol at 30 g l. GF 677 does not seem to be an efficient utilizer of sucrose for In vit...

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...

late ripening citrus cultivars are very acceptable in the market. with respect to scarcity of late ripening citrus cultivars in iran, the project was conducted to produce a new late ripening cultivar for 21 years (1989-2009). the first phase (1989-1993) was started with controlled pollination between mineolla tangelo (citrus paradisi × c. reticulata) and changsha mandarin (c. changsha). after a...

In the last years, an important renewal of plant material from different breeding programs is taking place in apricot order to improve resistance biotic stresses, extension harvest season, fruit quality, and productivity. However, graft compatibility many these cultivars with most popular Prunus rootstocks unknown, this essential agronomical trait for their better performance longevity. Hence, ...

An investigation entitled, “Effect of different rootstocks and scion compatibility study on Rosa sp.’’ was conducted to the graft compatability growth performance grafted rose plants experiment in Vegetable Research Station, Tamil Nadu Agricultural University, Palur, Cuddalore district, during year 2022. It carried out using completely randomized design (CRD) with fifteen treatments (T1- Andhra...

budding is a good method of propagation in the persian walnut (juglans regia l.)., however, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. this study was conducted to compare various budding methods and cut below budding :union: on two and three-year-old persian walnut under field conditions. the experiment was conducted bas...

Budding is a good method of propagation in the Persian walnut (Juglans regia L.)., However, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. This study was conducted to compare various budding methods and cut below budding union on two and three-year-old Persian walnut under field conditions. The experiment was conducted based...

We evaluate copper tolerance and accumulation in Vitis vinifera ssp. sylvestris in populations from a copper contaminated site and an uncontaminated site, and in the grapevine rootstock "41B", investigating the effects of copper (0-23 mM) on growth, photosynthetic performance and mineral nutrient content. The highest Cu treatment induced nutrient imbalances and inhibited photosynthetic function...

In plants, it is possible to induce heritable transcriptional gene silencing (TGS) via RNA-directed DNA methylation (RdDM) using artificially synthesized small RNA (siRNA) homologous to the 5'-flanking region of the target gene. As the siRNA signal with a specific RNA determinant moves through plasmodesmata and sieve elements, we attempted to induce TGS of a transgene and an endogenous gene of ...

The aim of the present study was to investigate the importance of the preculture conditions on the survival of apple (Malus domestica Borkh., cv. Romus4 and rootstock M106) shoot tips cryopreserved using a combined droplet vitrification procedure. Preculture was critical for the survival of apple shoot tips after cryopreservation. Among the different tested sugars and sugar alcohols (glucose, s...
