Abstract
Cherry (Prunus avium) is a worldwide cultivated fruit tree.
This study aimed to determine the most influential factors for cutting propagation of six rootstocks.
The adaptability of these species to propagation by leafy stem cuttings was assessed in three separate experiments.
These experiments evaluated the effects of (1) genotype: six rootstocks including new cultivars of Prunus hybrids; (2) hormones: IBA, NAA: IAA (1:1) and ABT (30% IAA, 20% NAA and 50% amino acids) with concentrations of 800, 1000 and 1200 ppm respectively; (3) light in the propagator: 2 h morning light or shade whole day.
The results showed that IBA at 1000 ppm provided the greatest rooting rate of ‘Gisela 5’ and ‘Gisela 6’ at 82% and 81%. ABT at 1000 ppm provided the greatest rooting rate of ‘CDR-1’, ‘CDR-2’, ‘Colt’ and ‘Daqingye’ at 84, 87, 79 and 77%. Light treatment provided a greater rooting rate and accelerated rooting process than that control on ‘CDR-1’, ‘CDR-2’ and ‘Daqingye’. ‘Gisela 5’, ‘Gisela 6’, ‘CDR-1’ and ‘CDR-2’ had greater rooting rate with 3 or 4 remained leaves, while 2 or 3 leaves generated greater rooting rates than 1 or 4 leaves on ‘Colt’ and ‘Daqingye’. This study optimized the cutting propagation procedure of six cherry rootstocks, including two new selected Prunus hybrids rootstocks never reported before, the protocols we used can be used for commercial production.
