Effect of some treatments on rooting of cucumber cuttings (Cucumis sativus L.)‎

Abstract EN

A study was conducted at glasshouse, at Agriculture Faculty, Babylon University, Iraq, during 2013 growing season.

The auxiliary shoots (11-15 cm long) were taken from cucumber plants (cv.

DRB).

Six treatments (2, 4 ml / L humic acid or biozyme, 1000 ppm NAA and in water as control) were used.

The cuttings were based dipped for 2 minutes according to the treatments, and then planted (as individual) in pots filled with sandy soil + peat (1:1).

All the treatments were triplicate by using complete randomized design.

Each experimental unit contained 10 cuttings.

The data were recorded on survival percentage, root number per cutting, longer root length (cm), root volume (cm3), root fresh weight (g), root dry weight (mg).

The results showed that the highest root number per cutting (24), longer root length (23.3 cm), root volume (3.0 cm3), root fresh weight (3.1g) and root dry weight (332.3 mg) were obtained from NAA treatment.

Humic acid and biozyme at 4 ml / L were superior significantly in roots number per cutting as compared to control.

All treatments showed a significant increases root fresh and dry weight as compared to control.

Shoot survival percentage was not affected by treatments.

It proved that cucumber auxiliary / lateral shoots can be grown successfully.

It is a quick and easy way to grow the second crop of the same variety without seed cost.
