(Effect of shading and spraying with alcoholic sugars on the physiological lifespan of Seeds celery plant)

The experiment was carried out at the research station north Ramadi city of the College of Agriculture – University Of Anbar to study the effect of shading and spraying with sugar alcohols (sorbitol) on the physiological lifespan of celery (Apium graveolens L.). The experiment included two levels of shading (0 without shading and 50%) with symbols (S0 and S1) sequentially and spraying with sugar alcohols (sorbitol) at three levels (spraying with distilled water only, 10 and 20 mg L-1) with symbols (K0,K1 and K2) sequentially. The characteristics of plant height, stem diameter, chlorophyll content of leaves, number of days from planting to flowering, number of days required for complete flowering and number of days required for seed maturation were studied.The results showed that the percentage of shading S1 (50%) led to a significant increase in stem diameter and the chlorophyll content of the leaves, while the level of shading S0 (with out shading) significantly increased the height of the plant, the number of days from planting to flowering, the number of days required for full flowering, and the number of days required for seed maturity. As for the spraying factor with alcoholic sugars, the spraying level K3 (20mg L-1) was significantly superior in stem diameter and the chlorophyll content of the leaves. As for spraying with distilled water only, it was significantly superior in the number of days from planting to flowering, the number of days required for complete flowering, and the number of days required for seed maturity.
