Dry matter accumulation was observed more during the day time and lesser amount in the night period. An inverse relationship between dry matter production and water content was observed. Regarding the carbohydrate synthesis, all fractions of sugars were found to be affected considerably. In general, the least amount of carbohydrate was obtained at sun rise and greatest at sun set.enArticle
