Conteúdo: 	This work dealt w ith the effect of the in terval of; harvesting top growth on the storage of reserve carbohydrates in roots t underground s tem s, and stem b a ses of Sabi Guinea g ra s s . Percentage of to ta l a v a il­ able carbohydrates in the storage o rg an s, dry weight of th e se o rg an s, growth stage of the p lan ts , height of the f irs t l e a f , number of shoots per plant, and clump b asa l area, were determ ined every 15 days throughout the experim ental period. The cutting treatm ents stopped growth of the storage organs and Caused a temporary lowering of the percentage of reserve carbohydrates in th ese o rg an s. Only with the 30-day cutting w as there a general decline of to ta l availab le carbohydrates over the study period.: The 30day in terval and the 60-day in terval harmed the p lan ts the most; the f irs t b ecause it w as too short for the p lan ts to recupera te , the second, because the p lan ts were cut a t c ritic a l growth s tag es during seed for­ m ation. The 75-day cutting in terval was benefic ia l to the p lan ts , in tha t , by removing the old stem , the p lan ts were given a chance to s ta rt new growth which resu lted in a healthy development of the storage o rg an s. ; ' ' ’ ; . Basal area and number of shoots per plant were greater a t the end of the season for p lan ts cut a t 45-day or 75-day in te rva ls compared to v iii those, cut a t 30or 6-d ay in te rv a ls . Clipping a t the 60-day in terval resu lted in slow recovery in leaf height following clipp ing .
