Effect of different media on chlorophyll and carotenoids of ornamental plants under system mist

Ali Salehi Sardoei and Parviz Rahbarian

An important factor in the growth medium of plants and chemical plants. native substrates can be used to improve plant performance. To evaluate the effect of growth medium on Padanus sanderi and Rosmarinus officinalis experimental design was completely randomized with eight treatments and four replications were carried out in the research greenhouse of Islamic Azad University of Jiroft. The results of these tests indicate that the media different were effective on production of Photosynthetic pigments of Padanus sanderi and Rosmarinus officinalis. Higher values of chlorophyll a, b were total, carotenoids and sum pigments in levels of 50% peat palm + 25% sand + 25% perlite, with averages of 11.35, 7.43, 18.78, 3.47 and 22.25
g.ml-1. Add 25% sand + 25% perlite substrates on growth indices such as photosynthetic pigments Padanus sanderi and Rosmarinus officinalis were obtained, The highest value obtained in other indexes which show pure increase in beds with sand + perlite to grow their substrates. Higher values of chlorophyll a, b were total and sum pigments in levels of 50% peat moss + 25% sand + 25% perlite, with averages of 14.94, 7.26, 22.21 and 26.21
g.ml-1 for Rosmarinus officinalis.
