Abstract
This study was conducted in the laboratory of tissue culture of the date Palm Research Center / University of Basra in 2007 to determine the effect of spraying and irrigation with different concentrations of fertilizer triple NPK is (zero, 300 600 and 900 mg / L) in the growth of plantlets date palm Berhi propagated by in vitro. The results showed the following: 1 - increase the proportion of plantlets acclimatization when sprayed fertilizer triple concentration 600 mg / L and lead a moral for the rest of the concentrations, amounting to 100% compared to the treatment of comparison 30%, and the watering plantlets fertilizer triple led to a significant increase in the proportion of plantlets acclimatization it reached 90% compared to the treatment of comparison 30% 2 - The results showed that spraying with (600 mg / L) have been led to give the highest rate of leaves the new formed and was (4) leaves / plantlet and (3) leaves / plantlet through the process of irrigation, while the number of new leaves was 1 in the treatment of comparison . 3 - The results showed that the spray irrigation concentrate (600 mg / L) gave the highest rate of leaf length and total (26.75 22.35) cm and a difference of moral for the rest of the concentrations and the lowest rate to the length of the leaves was in the treatment of comparison and total (13.19 cm). 4 -: The spraying and irrigation focusing (600 mg / L) has led to accord the highest rate of roots formed and reached (8.14) and (6.95), respectively, a difference of moral the treatment in the case of spraying, while given treatment comparison less with the rate of the roots formed ahead significant for the other treatments (1.57). 5 - The results showed that spraying with 600 mg / L led to reduce the time for the emergence of the first leave it reached a new 20-day period, while the period increased to 34 days in the treatment comparison. 6 - The process of spraying plantlets fertilizer triple concentration of 600 mg / L led to a significant increase in the amount of total chlorophyll, amounting to 3.86 mg / 100 gm weight is tender and a significant increase in the amount of wax, amounting to 0.0996% and a significant increase also in the average number of stomata in the leaves as of 104 gaps / mm 2.
