the effect of stationary liquid media to improve shoots elongation in date palm cv. najda and an in vitro pre-acclimatization stage to increase the survival ercentage of plantlets in the greenhouse was investigated. two basal liquid media were tested: full strength and half strength murashige and skoog medium (ms). media were devoid of plant growth regulators (pgrs), containing 0.5 mg/l 6-benzy...

EFFECTS OF CARBON DIOXIDE ENRICHMENT AND IRRADIANCE ON EX VITRO ROOTING, ACCLIMATIZATION AND SUBSEQUENT GROWTH OF MICROPROPAGATED APPLE AND BLUEBERRY. Marvin Pritts and Dorcas Isuta*, Cornell University, Fruit and Vegetable Science Department. 134A Plant Science Building, Ithaca, NY 14850 Previous findings reveal that rooting and acclimatization of apple and blueberry plants is often difficult ...

In vitro micropropagation is already a current multiplication tool for walnut self-rooted cultivars and rootstocks, but grafting still performed in the field or greenhouses, mainly using seedlings as rootstocks. The present work describes new approach to obtain clonal walnut-grafted plants, involving shoot production of ‘Paradox’ (Juglans hindsi × Juglans regia) cl. ’Vlach’, be used rootstock, ...

Agar substrates for in vitro culture are well adapted to plant micropropagation, but not to plant rooting and acclimatization. Conversely, paper-pulp-based substrates appear as potentially well adapted for in vitro culture and functional root production. To reinforce this hypothesis, this study compares in vitro development of nemesia on several substrates. Strong differences between nemesia ro...
