Seasonal changes of photosynthetic pigments and proline in sea grass Halodule uninervis F. from Hormozgan Province in Persian Gulf

In this research, the Halodule uninervis sea grass was collected in the tidal area of Golshahr (Bandarabaas-Iran) in maximum period of ebb in summer-autumn- winter 88 to spring 89. The physiological analysis of Halodule uninervis was performed three times by measuring Photosynthetic pigments (Chlorophylls a, b and Carotenoids) and the amount of Prolinewas also investigated. The results indicated that the minimum amount of Chlorophyll a was found in spring (1/19 ± 0/002 mg/g) and the minimum amount of Chlorophyll b (0/68 ± 0/003 and 0.68 ± 0/003 mg/g) and Carotenoids (1/25 ± 0/002 and 1/26 ± 0.002 mg/g) was found in autumn and winter respectively. The Proline measurement revealed that the amount of Proline in roots was less in comparison to the leaves and the minimum amount of Proline found in roots was in spring (0/07 ±0/006 mg/g) and summer ( 0/08 ± 0.004 mg/g).
