until the canopy shows stunting, premature defoliation and branch dieback ( Naqvi, 2004 ). Foot rot infection begins above the soil surface where a lesion on the bark can extend from the scion to the base of the rootstock ( Savita and Nagpal, 2012 ). Gum

citrus ‘US-942’ rootstock reacted to salinity, which has not been studied before ( Bowman and McCollum, 2010 ). Should ‘US-942’ rootstock react similarly to the other plant species that have been tested, the apoplastic barriers will develop closer to the

The use of rootstocks in viticulture was initiated in response to the widespread destruction of European vineyards after the inadvertent introduction of the grape phylloxera ( Daktulosphaira vitifoliae ) during the mid-19th century ( Ordish, 1972

commence until the 19th century ( Mudge et al., 2009 ). The most used rootstocks for grafting before the 1970s were sour orange ( Citrus aurantium ) and rough lemon ( Citrus ×jambhiri ). As the importance of rootstocks for citrus production was recognized

, because most fruit trees and many vegetables are grafted ( Lee, 1994 ). So we grafted potato ( Solanum tuberosum L.) scions onto Me tomato rootstock to test whether the RNA molecule can move from Me tomato and whether it alters the potato leaf

resistance conferred by the rootstock ( Navarrete-Mapen et al. 2020 ). Selected rootstocks provide excellent levels of tolerance in vegetables to devasting diseases caused by fungi, oomycetes, and bacteria such as Didymella bryoniae , Fusarium

The effect of three vigor-control apple (Malus domestics Borkh.) rootstock (seedling, MM.106, and M.7a) on fruit diameter of three cultivars ('Red Delicious', `Granny Smith', and `Gala') was studied over two growing seasons (1990-91) in the arid climate of Willcox, Ariz. Daily fruit growth rate (DFGR) and effective fruit growth period (EFGP) data indicate cultivar differences in DFGR as well as EFGP. Cultivars with a high DFGR had a relatively shorter EFGP. Rootstock had no significant effect on EFGP. Cultivar x rootstock interaction on fruit diameter was significant for DFGR, but not for EFGP. `Red Delicious' and `Granny Smith' trees produced larger fruits on MM.106 and M.7a than on seedling rootstock. For `Gala', there was no significant effect of all rootstock on fruit diameter.
