Abstract Experiments were conducted in Ash-Shoubak area of Jordan from June 2003 to September 2005 to study the effect of three apple rootstocks on the development of the small red-belted clearwing borer, Synanthedon myopaeformis (Borkh.) (Lepidoptera: Sesiidae), under field conditions. Mondial Gala apple trees grafted on the dwarfing rootstock M9 and the semi-dwarfing rootstock M26 were equall...

A prerequisite for reliable hydraulic measurements is an accurate collection of the plant material. Thereby, the native hydraulic state of the sample has to be preserved during harvesting (i.e., cutting the plant or plant parts) and preparation (i.e., excising the target section). This is particularly difficult when harvesting has to be done under transpiring conditions. In this article, we pre...

The aim of the present study was to investigate the importance of the preculture conditions on the survival of apple (Malus domestica Borkh., cv. Romus4 and rootstock M106) shoot tips cryopreserved using a combined droplet vitrification procedure. Preculture was critical for the survival of apple shoot tips after cryopreservation. Among the different tested sugars and sugar alcohols (glucose, s...
