Effect of planting media and IBA concentration on rotting ability of stem cutting of Ligustrum ovalifolium

الملخص EN

This study was carried out in the Agricultural College/ Salahalden University during the period between 1st March, 2010 to 1st August, 2010, to investigate the effect of planting media (sand, sand : loamy soil, and mixture of sand: loamy soil: peat moss) 1 : 1 : 1 by volume, and IBA concentrations (0, 1000, 2000, 3000) mg.l-1 on rooting ability of stem cuttings of Ligustrum ovalifolium.

The results show that the mixture of sand, loamy soil, peat moss is significantly superior than other media and give the highest values of roots number 7.45 root/plant, roots dry weight 0.33 g / plant, shoots number 3.92 shoot/plant, leave number 11.00 leaf/plant, and vegetative dry weight 3.76 g / plant while the best rooting percentage 64.63 % is obtained in cutting which are planted in peat moss and the longest root is for cutting which are planted in sand media.

The 2000 and 3000 mg.l-1 IBA causes significantly increase in rooting percentage 68.92, 68.42 %, longest root 3.41, 3.36 cm, roots dry weight 0.31, 0.31 g, leave number 9.67, 9.56 leaf/plant when comported with the other concentration.

In the other hand the 3000 mg.l-1 is significantly superior in roots number 5.91 root/plant, shoots number 3.92 shoot/plant, and vegetative dry weight 2.82 g / plant.

The interaction between planting media and IBA concentrations case significantly variance in all rooting and shooting parameters and the highest values are for cutting treated with 2000, 3000 mg.l-1 and planted in deferent media.
