Recent History. Product Information. Copy Link Tweet This. Daniel Kamarudin , Michael McMahon. Original electronic Scanned image These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching.
However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background. For printed books, we have performed high-resolution scans of an original hardcopy of the book.
We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format.
Both download and print editions of such books should be high quality. Here is a sample of a page from a watermarked title:. File Last Updated:. Publisher Average Rating. See All Reviews.

The built in size controlling mechanism of the rootstocks affords a relatively cheap and permanent method of controlling trees within a predetermined size Mitra, Ananda, have also stated that the stomata distribution as an index for predicting the growth potential of apple rootstock has revealed that it was high in the vigorous rootstocks like M 25, MM and MM and low in the dwarfing cultivars like M 9.
In general, the trees are more vigorous on MM series clones than on M clones. M 7 rootstocks both as inter-stock and rootstock produced smaller trees with minimum tree volume and scion girth. The rootstocks effects varied widely with different cultivars.
The greater suitability of M 9 and M 26 for standard cultivars and of MM and MM for spur type cultivars was confirmed Strada and Fidegheli, Highest growth was observed on plants on MM rootstocks Cepoiu and Marval, Source: Hartmann et al. Their poor anchorage was due to brittle nature of roots rather than being shallow rooted.
One important benefit of using dwarfing rootstock is its utilization in high density planting HDP. Red Delicious Jonathan and Rymer when grafted on M 13 attend maximum girth, highest plant height, larger spread and higher plant volume.
Chandal and Chauhan, reported that Starking Delicious on MM rootstock had higher stomata resistance and maximum transpiration rate whereas the minimum stomata resistance and maximum transpiration rate was recorded on M 25 rootstocks.
Similarly, the trees on Bud were larger than on Ottawa 8 and smaller than on Ottawa 11 but were less efficient than those on Ottawa 8 and on other dwarfing rootstocks like M 8, M 9, M 26, and Ottawa 3 Mitra, Precocity and flowering If the tree can be dwarfed by artificial means of an rootstock, the size of the trees can be controlled and they can be forced to be early, producing better crops Kanwar, M. Flowering of the seedlings was hastened on M 9 and retarded on M 16 rootstock, irrespective of the influence of rootstock or interstock growth.
Even the very unprecocious Northern Spy begins flowering by the fourth year on M9, when properly trained Mitra et al. Visser reported that M. One of the most striking attributes of M 9 is its capacity to induce early fruiting precocity in scion cultivars Mitra et al. Spur leaf number and spur leaf area were both high with vigorous rootstocks, whereas, spur density was low. Golden Delicious was precocious and productive on all rootstocks with fairly uniform performance on M 7 and M 26, but was extremely variable on M 9.
McIntosh performed best on M 7, being variable on M 26 and M 9. Fruit yield and Quality In a fourteen year test, the dwarfing stocks generally were more efficient than seedling in a number of cases; the more vigorous clonal rootstocks M 5, M 2, M 1, and M 16 also were more efficient than seedlings during the last five years Westwood, The spur type delicious strain produced more fruit per tree than non-spur strain like Red King Delicious with M 7 and MM but not with M 26 rootstocks.
Golden Delicious produced more fruit per tree than gold spur on all three stocks. Highest yield of spurred strains by 16 years data assessment were with MM stocks. It is generally accepted that clonal stocks are efficient producers than seedlings stocks. For this reason, more problems of graft incompatibility and fruit quality exist with pear.
In the past, the propagation by cuttings in majority of fruit trees was not successful making it imperative to resort to grafting and budding and in that case, the seed of commercial cultivars was used for raising the rootstock. Since such seedling rootstock does not impart any specific capability to the scion and efficient techniques of propagation through cuttings have developed, there is general trend in modern fruit culture toward growing cultivars on their own roots Rathore, A perusal of the available literature shows that rootstocks for pear have been used in Nepal without assessing their performances except for Quince Pyrus collerana for crown gall.
There is also little evidence to support the use of quince as an important rootstock in Nepal. Despite the lack of research findings, experience has shown that Mayal pear is extensively used as rootstocks for the oriental pear Asia Sand Pear in Nepal Khatiwada and Ghale, The recommended pear rootstocks in Nepal are Mayal seedlings and Quince Shrestha, Major effects of pear rootstocks on the scion cultivars: 3.
Tree vigor The need of dwarfing rootstocks for high density planting in pear is realized by commercial fruit growers, but satisfaction has not been achieved yet. Source: Westwood, Yields and quality In a number of rootstock trials, high yield, efficiency has been obtained in various cultivars: quince, Old Home X Farmingdale and P. Being vigorous, P. The fruits of both Bartlett and Anjou were higher in soluble solids than ever all others rootstocks among various quince rootstocks, EMA induced the lowest fruit acidity.
Generally, high soluble solids and acidity increase the fruit quality. Rootstocks exert more influence on acidity and firmness than on soluble solids Westwood, Yield efficiency is good on quince rootstock and on OH X F51 in high- density hedgerows. The use of Old Home as a compatible interstem for quince has consistently resulted in higher yield than when Hardy is used Westwood, Of the vigorous rootstock, P. Clonal OH X F rootstocks, however, were selected for their high-yielding potential, so they are better than unselected seedlings of the species.
Yet, P. Two fruit disorders related to rootstocks are hard end, caused by P. Fruit quality is generally good on quince, P. In 6-year-old trees, the yields of Cv. Westwood reported that in general, Pyrus ussuriensis, P.
Pest and disease resistant The new disease called pear decline has eliminate susceptible P. The pathogen migrates through the phloem downwards to the union. If the rootstock is susceptible, the phloem just below the union is killed effectively girdling the trunk. Compatibility Quince and pear often are incompatible and must be double worked with a compatible interstem. Old Home is better as an interstem than Hardy, which was used for many years.
The following list of cultivars indicates compatibility with quince. Trees on quince roots need support for best performance. The root system is much branched and fibrous, but large roots are brittle and tend to break under the weight of crop and wind. Similarly, in suckering ability, many good pear stocks tend to sucker profusely and they include Old Home, some clonal OH X F, quince, imported French, P.
An ideal rootstock should be of fast growing in the nursery, having higher compatibility, long living, bearing numerous seeds in the fruits and having higher percentage of nucellar seedling Paudyal, Among numerous citrus rootstocks used in the world, trifoliate orange Poncirus trifoliate , sour orange Citrus aurantium , rough lemon C. A very sharp knife is used to make a vertical cut in a smooth area of the rootstock about 2.
A horizontal cut about 1 cm 0. The point of the knife can be used to lift the bark along the vertical cut if necessary. The rough lemon was the most vigorous grower of all rootstocks studied. This was manifested in both shoots and root growth. Trior-citrange and trifoliate orange were the least vigorous of all rootstocks.
The rest of the rootstocks were intermediate in vigor with Blackman sweet orange ranking second to rough lemon. Blackman sweet orange rootstock was a more vigorous grower in comparison with standard sour orange.
Cleopatra mandarin and trifoliate orange had the largest root systems in relation to their tops as reflected in their least top to root ratios when compared to other rootstocks Abbadi, Plants on Jambheri and Trifoliate orange rootstock produced better growth, yield and survival Misra et al. Fig: 3 Characteristics of different citrus rootstocks.
Source: www. CO CLUSIO Rootstocks are the underground parts that give rise to root system and also exhibit unexpected effects in the growth and development of the scion variety. Rootstocks are beyond doubt, have manifold profits in plant perpetuation to exploit their enormous effects on the scion variety.
Once the orchard is established, there is little possibility to reestablish it so it is worthwhile to consider the effects of rootstock to the scion variety. Here the need arises to use it. In western countries, there are numerous studies regarding the effects of rootstocks to the scion wood.
Furthermore, rootstocks are to be used to increase yield, to impart pest and disease resistance, to avoid other problems like salinity and low storability. There is immense scope for increasing production and productivity in many plants by exploiting such effects of rootstocks on scion cultivars.
