The grafting of fruits and vegetables influences fruit quality. The aim of the present work was to assess the effect of the rootstock and the scion on the antioxidant activity and the content in vitamin C, total phenols, lycopene and β-carotene of bell pepper. The cultivars Fascinato and Jeanette were used as scion and Terrano was used as rootstock. Four harvests in the production cycle of the ...
Plum bark necrosis-stem pitting (PBNSP) disease was first observed in 1986 affecting plum (Prunus salicina Lindl.) cv. Black Beaut trees in two orchards in Dinuba, CA (8). All of the Black Beaut plum trees had been whip-grafted with a single cultivar Wickson plum scion per tree to serve as a pollenizer, and all Wickson grafts failed. A year later, the same trees were grafted a second time with ...
Grapevine Grafting: Scion Transcript Profiling and Defense-Related Metabolites Induced by Rootstocks
Rootstocks are among the main factors that influence grape development as well as fruit and wine composition. In this work, rootstock/scion interactions were studied using transcriptomic and metabolic approaches on leaves of the "Gaglioppo" variety, grafted onto 13 different rootstocks growing in the same vineyard. The whole leaf transcriptome of "Gaglioppo" grafted onto five selected rootstock...
We investigated the effect of target mRNA level on grafting-transmitted gene silencing in tomato plants by using a strong ACC oxidase 1 (ACO1) silencer as the stock and transgenic ACO1 overexpressers as scions. Manifestation of graft transmission of sense gene silencing required a high initial level of target mRNA in the scion. A relatively high level of siRNA, similar to that in the strong ACO...
In order to separate the effects of size and meristem maturation on age-related changes in shoot growth behaviour, a reciprocal grafting experiment was conducted involving juvenile (J), mid-age (MA) and old-growth (OG) red spruce (Picea rubens Sarg.) trees as both scion donors and rootstock. The effects of rootstock and scion age on vegetative growth, foliar morphology and reproductive developm...
Boron (B) deficiency stress is frequently observed in citrus orchards and causes considerable loss of productivity and fruit quality. Carrizo citrange (Cc) has been reported as a rootstock more tolerant to B deficiency than Trifoliate orange (To). The 'Newhall' navel orange (Ns) performed better when grafted onto Cc (Ns/Cc) than when grafted onto To (Ns/To) under long-term B deficiency. The pre...
Leaf senescence is not a passive degenerative process; it represents a process of nutrient relocation, in which materials are salvaged for growth at a later stage or to produce the next generation. Leaf senescence is regulated by various factors, such as darkness, stress, aging, and phytohormones. Strigolactone is a recently identified phytohormone, and it has multiple functions in plant develo...
Apple scions with diverse growth habits were grafted on various size-controlling rootstocks and morphological characteristics were measured after 6 years of growth in the field. Scion had more influence than rootstock on monthly growth rate. Across all rootstocks, scions with spreading growth habits grew rapidly in April and May and achieved most seasonal growth earlier than scions with upright...
Two DNA sequences (VvPR1 and UT456) were selected by a functional screen to test for ability to suppress the Programmed Cell Death-dependent symptoms of PD. Greenhouse experiments confirmed that these two different anti-PCD DNA sequences prevented PD symptoms in the PD-susceptible cultivar Thompson Seedless and the commercial rootstock Freedom. Furthermore, the bacterial titer in the transgenic...
The effects of different Cucurbita spp. rootstocks on melon cultivars belonging to different horticultural groups were studied by comparing grafted plants with non-grafted ones under greenhouse and open ®eld growing conditions. Winter melons (Cucumis melo L.) of the Inodorus group, cvs. `Thraki', `Peplo' and `Lefko Amynteou', and a summer melon of the Cantalupensis group, cv. `Kokkini Banana', ...
