pistachio is the most important nut that is produced in iran. little research has been done to examine the effect of ucb1-hybride rootstock plants as tissue culture for pistachios (2011 in toba company).this study aims to evaluate three pistachio varieties on ucb1 hybrid rootstock.  the experiment was conducted as a randomized complete block design with three treatment groups (including ohadi, ...

The complete genome sequences of three related endogenous pararetroviruses (EPRVs) were obtained by 454 sequencing of nucleic acid extracts from Carrizo citrange, used as a citrus rootstock. Numerous homologous sequences have been found in the sweet orange genome. The new EPRVs are most closely related to petunia vein-clearing virus.

Root pressure was measured continuously over spring in eight clonal kiwifruit rootstocks selected from seven Actinidia species (A. chrysantha, A. deliciosa, A. eriantha, A. hemsleyana, A. kolomikta, A. macrosperma, A. polygama), using pressure transducers and miniature compression fittings. Rootstocks that promoted scion vigour developed root pressures up to 0.15 MPa before or during scion budb...

SUMMARY Avocado seed are usually considered as waste or as a source of seedlings suitable for use as rootstocks. This paper emphasizes the changing composition of avocado seed and how as a storage organ certain constituents are translocated from it to other portions of the fruit or tree. The fresh and dry weight and some of the inorganic constituents were determined in the dry matter of the see...

The efficiency of a hybrid systems method which combined artificial neural networks (ANNs) as a modeling tool and genetic algorithms (GAs) as an optimizing method for input variables used in ANN modeling was assessed. Hence, as a new technique, it was applied for the prediction and optimization of the plant hormones concentrations and combinations for in vitro proliferation of Garnem (G × N15) ...

Grafting is a centuries-old technique used in plants to obtain economic benefits. Grafting increases nutrient uptake and utilization efficiency in a number of plant species, including fruits, vegetables, and ornamentals. Selected rootstocks of the same species or close relatives are utilized in grafting. Rootstocks absorb more water and ions than self-rooted plants and transport these water and...

Salinity is one of the most important problems that restrict cultivation of crops in arid and semi-arid regions. Pistachio (Pistacia vera L.) is one of the most important trees that grow in these restricts. In this greenhouse study, the effects of salinity on growth of pistachio rootstock Badami evaluated. Seedlings were grown in plastic bags containing perlite. Salinity was imposed, by adding ...

The choice of rootstock has a significant impact, not only on fruit growth and development, but also avocado quality postharvest performance. objective this study was to evaluate compare attributes related the Hass avocados from “Mexicola” “Duke 7” rootstocks grown under similar conditions. This included two harvests: early (23–26% dry matter) middle (>26–30% per season for 2016/2017 2017/20...

Agrobacterium tumefaciens biovar 1 strain 186 was isolated from a walnut tree expressing crown gall symptoms. The draft genome sequence of this strain harbored genes for crown gall formation and will be useful for understanding its virulence on Paradox, the predominant hybrid rootstock used for the cultivation of English walnut in California.

Due to climate changes, drought- and lime-tolerant Prunus mahaleb rootstock may gain importance. Among the Mahaleb rootstocks hybrids, there are standard moderate-vigorous types, but their intensive testing in orchards is still needed. Our paper reports on SL 64, Bogdány, Magyar, SM 11/4 clonal Mahalebs, hybrid MaxMa 14. ‘Carmen’, ‘Vera’, ‘Paulus’, ‘Rita’ sweet cherry trees were trained above p...
