Abstract:
Phoenix dactylifera L. belongs to the family Palmae or Arecaceae. Date palm require artificially pollination for fertilization and fruit set due to dioecious condition. Storage of pollen is an important concept to make availability of pollen at the time of pollination. Pollen viability is important for species dispersal, fitness, and survival of the next plant generation. The experiment conducted at Date palm Research Centre, SKRAU, Bikaner from March 2020 to July 2021. There were twelve treatment combination made for stored pollen application viz., glass bottle stored at room temperature (T₁), plastic bottle stored at room temperature (T₂), polythene bag stored at room temperature (T₃), paper bag stored at room temperature (T₄), glass bottle stored at refrigerator 5 °C temperature (T₅), plastic bottle stored at refrigerator 5 °C temperature (T₆), polythene bag stored at refrigerator 5 °C temperature (T₇), paper bag stored at refrigerator 5 °C temperature (T₈), glass bottle stored at deep freeze (-15 °C) (T₉), plastic bottle stored at deep freeze (-15 °C) (T₁₀), polythene bag stored at deep freeze (-15 °C) (T₁₁), paper bag stored at deep freeze (-15 °C) (T₁₂). Performance of treatment T₉ found superlative followed by T₁₀ in respect of fruit set, quality and yield attributes.
