This study was conducted to investigate the effect of pollen type (Green ghanamy (G), Red ghanamy (R) and a mixture of Green ghanamy and Red ghanamy (GR) on fruiting and some fruit characteristics of off-shoot and tissue culture date palm (Phoenix dactylifera L.) cv. Barhi as a factorial experiment based on a randomized complete block design with 3 replications. In this study, thirty-six 10-year-old palm trees (18 off-shoot and 18 tissue culture Date Palm trees) were selected and examined for 180 days. Based on the results that GRO treatment had the highest percentage of dry weight (54.46) and the lowest fruit moisture percentage (45.53). The lowest length (26.99 mm), diameter (18.77 mm) and fruit weight (6.97 g) were obtained in RT treatment at the Tamar stage. GRO fruits had the highest pH (7.33), TSS (56.38%), TSS/TA (445.90) and carbohydrates (45.33%) but the GRT fruit had the lowest pH (6.72), TSS (42.35%), TSS/TA (293.35) and carbohydrates (24.33%). Maximum fruiting rate (100%) and non-parthenocarpy fruit were reported in dates palm pollinated with all three types of pollen grain treatment; while using R pollen grains and GR was better than G in this type of date in terms of quantitative and qualitative characteristics of the fruit. Fruiting and parthenocarpy percentage were obtained 79.13% and 20.87% in tissue culture dates pollinated with R pollen grains in compered with other pollen grain treatments. |
