In order to clarify the influence of the rootstock cultivar and fruit storage on the texture of cucumber (Cucumis sativus L.) fruit, we examined the physical properties of the fruit, i.e., flesh firmness, placental firmness, skin toughness, and the crispness index. Cucumber fruits from own-rooted plants and from plants grafted onto the three rootstock cultivars of ‘Shin-tosa’ (Cucurbita maxima ...

Professor Hume was right: rootstocks are critical and much is still to be learned. Rootstocks and scions are the foundation of many tree fruit industries of the world. Together, those components establish profitability, but it can be argued that the rootstock is the critical component; otherwise, scions would be grown on their own roots everywhere. There is no precedent for the failure of a cit...

Xylella fastidiosa (Xf) is the causative agent of Pierce’s Disease (PD). Collectively, a team of researchers (Lindow, Dandekar, Labavitch/Powell and Gilchrist) has identified or constructed and advanced the evaluation of five (Table 1) novel genes (DNA constructs) that, when engineered into grapevines, suppress symptoms of PD by reducing the titer of Xf in the plant, reducing its systemic sprea...

INTRODUCTION Collectively, a team of researchers (Lindow, Dandekar, and Gilchrist) identified, constructed and advanced to field evaluation five novel DNA constructs (Table 1) that, when engineered into grapevines, suppress symptoms of Pierce’s Disease (PD) by a) reducing the titer of Xylella fastidiosa (Xf) in the plant, b) reducing systemic spread of the bacteria or c) blocking Xf’s ability t...

To evaluate the role of root-synthesized ABA in regulating growth and stomatal behaviour under well-watered conditions, isogenic wild-type (WT) and ABA-deficient flacca (flc) tomato (Solanum lycopersicum) were reciprocally and self-grafted just below the cotyledonary node. Since flc scions had lower leaf water potentials due to higher transpiration rates, a subset of all graft combinations was ...

Sour cherry (Prunus cerasus L.), having a rich composition of biologically active connections and antioxidants, is gaining increasing popularity among agricultural producers. Increasing the production sour fruits requires introduction modern technology, one elements which low-growing rootstocks. For many cultures, use rootstocks has been widely studied, but there very little information on thei...

"Lane Late" sweet orange grafted on six different citrus rootstocks and grown in the Guadalquivir valley (Seville, Spain) were picked at different ripening stages in two consecutive seasons to characterize their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition) and quantify their main antioxidant compounds (vitamin E and vitamin C). Linea...

rootstock and cultivar selection is the most critical decision at the time of an apple orchard establishment. tree size, yield and fruit quality are affected by roostock and cultivar. non-sufficient study of rootstocks and cultivars effects on mentioned traits will lead to incorrect result or failure in orchard managing. in this study the effects of three vegetative rootstocks (mm106, mm111 and...

A protocol for micrografting shoot tips harvested from in vitro shoot cultures directly to transplanted rootstock plants in the greenhouse was developed. Shoot tips of the apple (Malus domestica) cultivars Golden Delicious, Granny Smith and Fuji clone, Nagafu12, were harvested, stored in a water bath then prepared for grafting by cutting the stem immediately below the tip into a wedge shape lea...

BACKGROUND AND AIMS Previous studies indicate that the size-controlling capacity of peach rootstocks is associated with reductions of scion water potential during mid-day that are caused by the reduced hydraulic conductance of the rootstock. Thus, shoot growth appears to be reduced by decreases in stem water potential. The aim of this study was to investigate the mechanism of reduced hydraulic ...
