Topic: Rootstock


  
  Rootstock - Wikipedia, the free encyclopedia
A rootstock is a stump, which already has an established, healthy root system, used for grafting a twig from another tree.
The scion is the tree which has the fruiting properties desired by the propagator, and the rootstock is the working part which interacts with the soil to nourish the new tree.
Rootstocks are studied extensively and sold with a complete guide to their ideal soil and climate.

 Grafting Rootstock   (Site not responding. Last check: 2007-10-31)
Continue the cut down the length of the rootstock until it creates a flap that is equal in length to the long cut on the scion.
The flap on the rootstock can be trimmed to match the short cut on the scion to yield a cleaner looking union on the grafted plant.
Prepare and attach a permanent label with the name of the variety, the name of the rootstock, the date the graft was made, etc. Keep the plant watered and in light shade as the graft union heals.

 Avocado rootstock-scion relationships
A comparison of rootstocks was pos­sible by grafting different rootstocks with the same source of scion; and a comparison of sources of the scion by grafting them onto the same rootstock.
The West Indians are known as the most sensi­tive, due to their origin, but when used as rootstocks the different types do not influence the sensitivity of the grafted tree, and its response to frost depends on the characteristics of the variety alone.
Changes in the rootstocks in use: The number of rootstock types in use in Israel was reduced from 600 in 1970 to 40 in 1985.

 Influence of Planting Site and Rootstock on Peach Tree Short-Life Performance of 'Redhaven' Trees
Therefore, the purpose of this study was to examine the influence of planting site and peach seedling rootstocks on scion susceptibility to PTSL as assessed by trunk growth, tree injury caused by cold stress and bacterial canker, and tree survival.
Thus, it appears to be possible that in the southeastern United States, Siberian C when used as a rootstock for peach may reduce the physiodormancy requirements of the scion cultivar, causing early deacclimation and scion injury, although the rootstock itself remains hardy and is not injured by the cold.
Influence of peach seedling rootstocks on growth, yield, and survival of peach scion cultivars.

 Citrus Rootstock Usage in the Indian River Region
The proportion of trees remaining on sour orange rootstock may be important in gauging the economic future for the Indian River citrus industry, especially for efforts to predict the duration of the current grapefruit oversupply.
A wide range of new citrus rootstocks is being developed by both the University of Florida and the USDA-Horticultural Research Laboratory in Ft. Pierce, FL, and promising rootstocks from other areas are regularly brought to Florida for evaluation.
Broader plantings and longer experience with the "best" new rootstocks will inevitably identify problems and limitations for at least some of them, but it is likely that a few of the current advanced selections will prove attractive and will be used for a substantial proportion of Indian River citrus production in the next twenty years.

 Inherent Influence of Rootstock Race on Avocado Fruit Maturity
Both types of rootstock trees are growing side-by-side on the same soil type and aspect and receive the same management with regard to PC treatment, nutrition and irrigation.
However, where rootstock race is known, and wherever the pure Mexican race rootstock trees are grown beside known local Guatemalan root-stock trees, earlier fruit maturity can be observed.
This great difference in time at fruit maturity of local Guatemalan rootstock race trees grafted to Mexican race rootstock has only been evident in 1991 as this is the first major crop to be produced by these trees some 7 to 8 years from planting.

 Walnut Rootstock Technical Report
The main obstacle in using wingnut as a rootstock is limited graft compatibility with English walnut cultivars.
In an 11-year ARS experiment completed in 1997, one seed source of wingnut was graft compatible with four of eleven English walnut cultivars, but wingnut compatibility with recently released walnut cultivars remains unknown.
ARS-Davis is cooperating with UC scientists M.V. McKenry and B.B. Westerdahl in evaluating lesion nematode tolerance among the six wingnut sources and standards of Paradox, English, and Northern California fl rootstock.

 Botany - Rootstock for Florida Roses   (Site not responding. Last check: 2007-10-31)
Fortuniana rootstock, the only rootstock of choice for South Florida gardens, also known as Double Cherokee, was discovered in Ninghpo, China by Robert Fortune around 1848, and sent by him to the Royal Horticultural Society in London.
The earliest mention of it use as a rootstock was in 1903 in Australia.
She collaborated with Dr. Samuel McFadden, an ornamental horticulturist from the University of Florida at Gainesville, where he tested Fortuniana rootstock extensively and developed a mist system for rooting cuttings that increased the success rate from 30% to 80-100%.

 Care needed in grape rootstock selection
Rootstock selection can be a daunting task for grape growers, but sorting through the pros and cons of alternatives for a particular vineyard site is essential for success, says Jennifer Hashim-Buckey, Kern County farm advisor.
While rootstocks can provide varying degrees of protection from soil pests and soil problems, selecting the best overall for a certain vineyard depends on array of factors, including scion compatibility, ease of grafting, irrigation, trellis design, soil depth and texture, soil chemistry and potential vine vigor.
That raised the question whether either of the two rootstocks might be a way to avoid the rejection component of the replant problem.

 Why Fruit Trees are Grafted
This baby tree of pencil diameter, which receives the scion and has its top cut off and discarded, is called a "rootstock," and it and the scion remain together all their lives.
Of course it is also possible to propagate a named variety by taking cuttings and inducing them to root, but with fruit trees this is a lengthy process, and even then the percentage of successes is not high.
Moreover rootstocks can be chosen that are able to confer advantages to the final tree, which we will explain later.

 Merits of topping rootstock - UBC Botanical Garden Forums
Some of the reason that I keep the rootstock and new grafts in 4” pots is weight and space.
The rational that I was given to top the rootstock was that it will encourage branching and that two or four branches will put out more leaves than one leader.
I have bought rootstock in the past that had been topped and it grew very well, but I didn’t have a control for comparison.

 Texas Citrus - Rootstock and Scion Varieties
The choice of a rootstock and scion variety is still a fairly easy proposition in Texas citrus, primarily because of the traditional nature of the Texas industry--ours is a fresh fruit industry based on high quality, red-fleshed grapefruit, complemented with a very few orange varieties.
The success of a rootstock is determined by its tolerance to prevailing conditions of soil, climate and disease, while still producing high yields of good quality fruit.
Until a better rootstock than sour orange emerges or until the dual threat of citrus tristeza virus and the brown citrus aphid appears eminent in Texas, there is not likely to be any significant change in rootstocks in Texas citrus.
