Callus Initiation

Recent studies have showed the importance and destruction of mangroves. So their restoration through tissue culture study is urgently required because in vivo propagation is plagued with unforeseen obstacles. In vitro investigation of mangroves found to be suitable material for salt tolerant mechanism studies and anti stress gene isolation. This study describes for the first time in vitro approach for rare species Sonneratia apetala Buch.-Ham. (Myrtales: Lythraceae) and herb species Suaeda maritima (L.) Dumort (Caryophyllales: Amaranthaceae) through callus. For this investigation, as a source of explants various part (leaf, intermodal and nodal segments) of both mangroves were used. These explants were cultured in various types of media (MS, LS, WPM, X and B5) with different combination of phytohormones (2, 4-D and NAA with BAP in combination). We also examined the effect of NaCl and seasons on callus initiation and growth. The highest rate of callus formation was obtained with nodal explants in MS medium supplemented with 1.5 mg.L^-1 NAA and 0.5 mg.L^-1 BAP in combination and 1 mg.L^-1 NAA and 0.5 mg.L^-1 BAP in combination for Sonneratia apetala and Suaeda maritime, respectively. We also found that callus initiation rate and growth decreased with increasing NaCl concentration higher than 80 mM and 120 mM for Sonneratia apetala and Suaeda maritima, respectively in MS media. This study also found that monsoon season was best time for invitro investigation of mangroves. The results presented here give an insight into the development of in vitro investigation suitable for mangroves. The initiated callus could be restored in low salaine or devoid of salaine land.

Spatial Locations

The biomass of three dominant mangrove species (Sonneratia apetala, Avicennia alba and Excoecaria agallocha) in the Indian Sundarbans, the designated World Heritage Site was evaluated to understand whether the biomass vary with spatial locations (western region vs. central region) and with seasons (pre-monsoon, monsoon and post-monsoon). The reasons for selecting these two regions and seasons are the contrasting variation in salinity. Among the three studied species, Sonneratia apetala showed the maximum biomass followed by Avicennia alba and Excoecaria agallocha. We also observed that the biomass varied significantly with spatial locations (p<0.05), but not with seasons. The variation may be attributed to different environmental conditions to which these forest patches are exposed to.

Avicennia Alba

Ethanolic extracts of pneumatophores of two mangrove species- Avicennia alba and Sonneratia apetala were studied in vitro for antioxidant capacity by measuring their ability to scavenge free radicals and determining total phenolic, flavonoid and tannin contents. In vivo measurement of antihyperglycemic activity of extracts was done by oral glucose tolerance test. In considering the antioxidant activity, S. apetala extract showed superior IC50 (concentration of sample required to inhibit 50% of free radicals) value for scavenging DPPH radical (71.77 μg/ml), hydrogen peroxide radical (97.27 mg/l), hydroxyl radical (79.62 mg/l) and superoxide anion (108.89 mg/l). For A. alba, the values for the radical scavenging assays were much higher. In addition, total phenol, flavonoid and tannin content demonstrated by S. apetala were 204.03 mgGAE/g, 228.68 mgQE/g and 235.89 mgGAE/g whereas for A. alba, they were 65.52 mgGAE/g, 44 mgQE/g and 37.71 mgGAE/g, respectively. In oral glucose tolerance test, S. apetala reduced the blood glucose level to a higher extent than A. alba. So, S. apetala with higher amount of secondary metabolites (phenol, flavonoid, tannin) is a superior source of natural antioxidants and antihyperglycemics. Dhaka Univ. J. Pharm.
