“…The field performance of apple trees grafted on micropropagated dwarfing rootstocks was previously shown to differ from that of trees grafted on conventionally propagated counterparts (Jones and Hadlow, 1989). Although apple trees with dwarfing rootstocks derived directly from micropropagation had many suckers and burrknots, those with dwarfing rootstocks propagated from cuttings derived from micropropagated plants showed improved growth, similar to that of trees with dwarfing rootstocks obtained by conventional propagation (Jones and Webster, 1993).…”

The field performance of 'Fuyu' and 'Hiratanenashi' Japanese persimmon (Diospyros kaki Thunb.) trees grafted onto rootstocks propagated from cuttings of root suckers of dwarfed trees (R-a and R-b) was investigated over seven years. The results were then compared with the performance of trees grafted onto seedling stocks (S) as well as that of micropropagated and own-rooted trees (O-R). Shoot growth of both cultivars on R-b was less vigorous than that on R-a, while tree height of 'Hiratanenashi' on R-a was the same as that of both S and O-R. Secondary shoots on R-b trees were scarce in both cultivars in the fifth and sixth years. On R-b, both cultivars bore flowers soon after field establishment and thereafter continued to do so abundantly, with the percentage of flower-bearing shoots on R-b trees being the highest for each study year. Yield efficiencies calculated by units of trunk cross-sectional area, canopy area, and canopy volume showed that R-b trees produced fruit most effectively, although the total yields during the three harvest years were not significantly different between rootstocks. The appearance of the graft union with R-b varied depending on the scion cultivar, but no union was damaged by the occurrence of several typhoons, which uprooted a number of trees. These results show the possibility of using R-b propagated by cutting as a dwarfing rootstock for persimmon trees. Overall, the R-b rootstock improved yield efficiency, although fruit quality requires further investigation because it is thought to be affected by rootstock type.

The rootstock plays a large role in modern citrus production because of its influence on tolerance to adverse abiotic and biotic soil-borne stresses, and on the general horticultural characteristics of the grafted scion. In recent years, rootstock has received increased attention as a management strategy to alleviate the devastating effects of the bacterial disease huanglongbing (HLB), also known as “citrus greening.” In commercial citrus nursery production, rootstocks are typically propagated by seed. Because of the increased demand for HLB-tolerant rootstocks, seed supply is often inadequate for the most popular cultivars. Cuttings and tissue culture (TC) propagation are alternative methods to supply adequate quantities of genetically identical rootstocks to be used as liners for grafting. However, there are concerns among nursery owners and citrus growers regarding the possible inferiority of rootstocks that are not propagated by seed. This study investigates the influence of rootstock propagation method on traits of sweet orange trees grafted on four commercially important rootstock cultivars during the nursery stage and during the first year of growth in a commercial citrus orchard. Several of the measured traits during the nursery stage, including rootstock sprouting, grafted tree growth, and root mass distribution were significantly influenced by the rootstock propagation method, but traits were also influenced by the rootstock cultivar. Our results also suggest that for tissue culture-propagated plants, differences in the starting material and the culturing method can affect the grafted tree behavior. Except for canopy spread and scion to rootstock trunk diameter ratio, tree growth during the orchard stage was determined by the combination of propagation method and rootstock, rather than by propagation method alone.

“…Increased suckering and burrknotting of micropropagated rootstocks was also reported in France by Villeneuve ( 1986). These effects are, however, not always consistent, as Jones & Hadlow (1989) showed that micropropagation had no effect on the suckering or burrknotting of the apple rootstock M.27, although it did increase suckering of M.9 and M.25. Navatel et al (1988) showed that although micropropagation increased burrknotting and suckering of a Pajam selection of M.9 compared with conventional propagation, the severity of the problem was greatly influenced by where the trees were eventually grown in France.…”
