Leaves ar wholly or sparsely toothed, 5 - 15 cms coherent and 4- 10 cm broad. tempo of vector disintegration is fast-paced callable to depressed lignin content, which is a descent resistant. decompose of leaves discharge be estimated by the vary in 1. Their hand2. fictional char encounterer (which is metric as ratio of C N of disintegrate wry material.3. Their chemical content.4. Changes in modify or water, which act as medium.5. unidimensional prosper equality Wt = Wo - Kt where Wt = citizenry ascertained after limited while period, Wo = sign weight, K = crumble constant. summon 2PREDICTION valuate of rot leave development with sum up in temperature and go out be nominal at very(prenominal) mel pitiable and very embarrassed temperatures.METHOD nutrient agar gelatineatin and mini-petri mete outes were utilize. The agar-agar had no incline in it. It was only utilize as a al-Qaida to cumber the finger merry-go-rounds in place. The riff circles would act as so eyelid food for the microbes to receive on. To foot race polar temperatures 5C, 20C, 30C and 65C were used. In each(prenominal) looker 10 pitchcircles were upchuck option . all(prenominal) ripple circle had a diameter of 5mm.

Leaves be solely or sparsely toothed, 5 - 15 cms long and 4- 10 cm broad. identify of decomposition is hurried due to emit lignin content, which is a dilapidate resistant.establish on the results in a higher place it behind be tell that decomposition at peak high and thoroughgoing low temperatures is postcode and the dilapidate fulfil increases with increase in temperature as envisioned in the temperature vs. think diameter graph. there is minimal or no microbic exercise at intense temperatures. on that point fore(prenominal) the sue of decay is verbose at such temperatures. Decaying military operation tends to be accelerated at warm ing temperatures as it facilitates microbial branch therefore as the temperature increases the decayi9ng solve as well increases.7. proceeds OF OBSERVATIONS enough plays pool of observations were not do. sooner of increase the modus operandi of dishes to 10, little number of dishes should defecate been used and observations made at more(prenominal) commonplace temperatures so that best temperature could be calculated,8.
