| Two field experiments were conducted during the two successive seasons of 2011 /2012 and 2012/ 2013 at Kaha Research Farm, Kaluobia Governorate Egypt, to study the effect of some treatments that stimulate germination, and planting dates on artichoke stumps which were sprayed with 1-Bio rooting compound by 10cm/liter every week for 45 days, 2- spraying stumps with 6-benzylamino purine (BA) at 20mg /liter weekly for 45 days, 3-dipping stumps for 30 minutes in 100 ppm indol butric acid (IBA) , 4- stumps were inoculated with a mixed inoculums consisted of 3 VA Mycorrhizal fungi i.e. Glomus etunictum, Glomus intraradices and Glomus monosporum , 5- Stump were cooled at (5°C) for two weeks. and 6-control plants without treatments. Two experiment were conducted first experiment was carried out in nursery in which treated stumps were planted in nursery in two planting dates, June1stand July 1st and transplanting in field after 45 days after every planting date. Data were recorded in nursery; on plant high, leaves number, offshoots number and roots number ,roots length and survival percentage after 45 days from every planting date. Second experiment was conducted in field to subsequent plants treated until production of flower heads. Data recorded in field on survival percentage, early, and total yield per fed. as a number, number of heads per plant, quality parameters of flower head and edible part in both early and total yield. Dry matter and inulin concentration in edible part in early and total yield were also recorded. Obtained data in first experiment indicated that the second date (July 1st ) gave increase significantly plant height after 45 days from planting. cooling and BA treatments affected plant height significantly compared with all other treatments after 45 days. The best number of offshoots was obtained from the first planting date and there were no significant differences after 45 days .The highest number of offshoots were achieved by the cooling treatment all over stages of nursery growth. It was noted that there was no significant effect of planting dates on the number of leaves after 45 days after planting , Results indicated that both of BA, the bio- rooting and mycorrhiza treatments increased the number of leaves during the nursery stage. Results show that all the interactions between cooling, BA and bio rooting treatments had increased in all vegetative nursery growth in both planting dates. The bio rooting and mycorrhiza improved roots number in first planting date. While the BA was the best treatment for the root length in first planting date. Survival% of plants in the nursery was not affected by planting dates. The highest percentages of survival in nursery were obtained from the cooling ,BA and bio-rooting treatments . The highest percentages of survival in field were obtained from the cooling and bio-rooting treatments in the second planting date. The second planting date gave the maximum number of head in early yield, also BA and bio-rooting treatments significantly influenced on early head yield and its quality. There were no significant effect of planting dates on the total yield and its quality. The cooling treatment improved significantly the total heads yield . But fresh weight of receptacles increased significantly with the BA, IBA and mycorrhiza, while the diameters of heads and receptacles were affected by the cooling treatment. Also, late planting date (July 1st) significantly increased dry matter and inulin content in total yield. Three pre- treatments of nursery mycorrhiza, BA and IBA enhanced dry matter and inulin content in early yield .While, cooling treatment significantly increased dry matter and inulin content in total yield. It can be concluded that stumps were planted in nursery on June 1st and treated with BA, bio- rooting and cooling improved all vegetative growth parameters in nursery, while planting date in July 1st with the same treatments gave the maximum values of early , total yield and quality parameters , as well as dry matter and inulin contents in both early and total yield. | ||||
