“…Soluble phenolic acids. Numerous monomeric and polymeric aromatic constituents are released upon extraction in 80 % methanol (Van Sumere 1989). This extraction releases free phenolics but leaves those bound by ester-linkages intact (Van Sumere 1989).…”

Senescent blades from the seagrass Halodule wrightii Aschers were suspended in the water column of Laguna Madre (Texas, USA) for a period of 419 d , representing the longest seagrass decomposition study to date. The initial stage of decomposition was characterized by a rapid loss of organic matter (36 % in 24 d ) attributed to leaching. A total of 76 % of the organic matter from seagrass tissues was lost by the end of the decomposition period. Of the major bulk constituents measured, neutral sugars were most abundant and accounted for 23 % of the ash-free dry wt of the initial senescent material. A complete and early loss of the cyclitol, myo-inositol, a reduction in glucose yields, and a relative enrichment in mannose were the most dynamic features of the neutral sugar fraction. An overall stability series: mannose > fucose > arabinose = rhamnose = galactose = xylose > glucose, reflects patterns of selective degradation of the polymers from which these sugars are derived. Soluble and ester-bound phenolic acids were lost from tissues at relatively high rates. Susceptibility of individual phenolic acids to removal from bulk tissue upon treatment with weak base correlated well to initial losses in the field. Early changes in total CuO oxidation phenol yields from H. wrightii were caused pnmarlly by the relatively rapid loss of soluble and ester-bound phenolic acids. Therefore, we took a new approach to quantlfy lignin-derived phenols by subtracting soluble and ester-bound phenols from total CuO oxldat~on ylelds. When these losses were taken Into account, lignin-derived phenol yields were similar from freshly senescent and highly degraded detntus. Cutln, although initially selectively preserved relative to bulk tissue, was also found at near initial yields In the highly degraded detritus. Overall, the distribution of polymeric constituents (cellulose, hem~cellulose, lignin and cutin) was similar in freshly senescent and highly degraded tissues suggesting that the compounds which comprise the ultrastructure of H, wrightij are degraded at similar rates Photobleached H. wriglitii blades were characterized by a much higher neutral sugar content, slmilar levels of cutin acids and a nearly complete absence of phenols con~pared to freshly senescent tissue. Photobleaching appears to be an important degradative mechanism which yields a polysaccharide-rich detritus that is devoid of the lignin signature characteristic of vascular plant tissues.

“…Microbial activity in soil is enhanced or suppressed by the ingredients of the soils. As an example presence of lignin and hemi-cellulose decreases microbial activity while presence of phenolic glycosides enhances microbial activity (Van Sumere 1989). This is due to the pH and EC values of soils due to the secondary products of degradation of these materials (Hoitinket al 1997).…”

The study was carried out as pot experiments using a Green Chilli variety, MI 2, and a Curry Chilli variety, Hungarian Yellow Wax (HYW) at the research field, Faculty of Agriculture, University of Ruhuna. The basal soil mixture was prepared using coir dust, sand, soil and cow-dong (1:1:1 control). Four different potting mixtures were prepared by adding tea waste, compost and inorganic fertilizer. The experiment was carried out according to complete randomized block design with four replicates at the rate of 8 plants per replicate. Plant height (cm), number of pods/plant, weight of pods per plant (g), pod length (cm) and pod appearance were recorded. Carbon-dioxide (CO 2 ) evolution method was applied to observe soil microbial activity in different soil mixtures.
