Determination of sapling growth characteristics in different growing substrates of Photinia x Fraseri 'red robin'

This study was carried out to determine the effect of 8 different media consisting of two different sized flower pots (3 l and 1,5 l) and different mortar mixtures on the plant growth in greenhouse conditions of Photinia x fraseri 'Red Robin' 8 plant. These environments are: 1. substrate (OR1): 10% coconut powder (HCT), 20% pumice, 30% garden soil, 40% leaf rotten (LW). 2. substrate (OR2): 10% HCT, 30% pumice, 30% garden soil, 30% YT. 3. substrate (OR3): 10% HCT, 40% pumice, 30% garden soil, 20% YT. 4. substrate (OR4): 20% HCT, 30% pumice, 20% garden soil, 30% YT. 5. substrate (OR5): 20% HCT, 20% pumice, 40% garden soil, 20% YT. 6. substrate (OR6): 20% HCT, 20% pumice, 30% garden soil, 30% YT, 7. substrate (OR7): 10% HCT, 30% pumice, 20% garden soil, 40% YT. Control substrate: 40% peat, 40% pumice and 20% garden soil. For this purpose, body diameter change (bottom-top) (ILC), plant height (BB), leaf length-width changes (YUG), number of leaves (YS), root weights (wet / dry) (KA), number of shoots (SS), plant crown (IT), flower weight increase - decrease ratios (SAA) were determined. The effect of these values on development was determined by statistical analysis under potted height, media, pot size x medium interaction (SBxO). Best results for ILC; flower pot height; 3 l, substrate; control, SBxO; 3 l - obtained from the control substrate. Best results for BB; flower pot height; 3 l, substrate; OR5, SBxO; 3 l - determined in OR3. Best results for YS; flower pot height; 3 l, substrate; OR7, SBxO; 3 l - obtained from the control substrate. Best results for YUG; flower pot height; the longest leaf 1,5 l, the widest leaf 3 l, substrate; the longest and broadest leaf control substrate and OR1, SBxO; measured at a maximum of 1,5 l - control substrate. Best results for KA; flower pot height; 3 l, substrate; highest age root weight control, the highest dry root weight OR1, SBxO; In the age, 3 l - control and OR1 were measured as dry, 3 l - control and OR3. Best results for SS; flower pot height; 3 l, substrate; OR4 - OR7, SBxO; not more than 3 l - OR4. Best results for IT; flower pot height; 3 l, substrate; OR2, SBxO: measured at most 3 l -OR1. Best results for SAA; flower pot height; 1,5 l, substrate; OR4, SBxO; highest 1,5 l - OR6. According to the results obtained from this study: Out of the control medium, it was determined that the 1st substrate was an alternative environment for Photinia x fraseri 'Red robin'.
