Description The experiment entitled “Effect of pollinizers on pomological traits and maturity of date palm
(Phoenix dactylifera L.) cultivars” was conducted at experimental orchard of department of
horticulture, CCS Haryana agricultural university, Hisar during 2015. Four different date palm cultivars
namely Hillawi, Zahidi, Khadrawi and Shamran and two pollinizers (P. dactylifera and P. sylvestris)
were selected for present investigation. The results indicated that fruit setting percentage and days of
doka stage were significantly affected by male pollinizer. Similarly fruit and quality characteristics like
fruit weight, fruit length, fruit breadth, fruit pulp, weight of seed, pulp stone ratio, bunch weight and
TSS was also significantly affected by pollen parent. While titratable acidity, total sugar, reducing and
non-reducing sugars were not affected significantly by male pollinizers.
Maximum fruit set (81.98%) and TSS (42.97 °Brix) were recorded from cv. Khadrawi
whereas maximum fruit length (4.69 cm) and Bunch weight (35.87 kg) were found in cv. Hillawi and
highest fruit breadth (2.63 cm) and weight of seed (1.64 g) were observed in cv. Zahidi by using P.
sylvestris as a pollen source. The pollinizer P. dactylifera with cv. Khadrawi gave maximum fruit
weight (14.17 g) and fruit pulp (12.44 g) while, with cv. Shamran gave highest pulp stone ratio (10.56).
Fruit maturity was one week earlier in all the cultivars when P. sylvestris used as pollen source. In
future, these experimental results will prove very useful for the induction of metaxenia effect in this
fruit crop.
