Summary

The present communication reports plant biomass and net production ofButea monosperma. The area of study, Borimalan forest block in Prasad range is 54 km south of Udaipur town (24°11′N and 73°42′E). From the present study it is concluded that:
  1. 1.

    A clear positive correlation between number of growth rings of bole and branches with their CBH (circumference breast height) has been observed. The regression equations obtained are: CBH=35.3+0.37 x Ngr. (for bole) CBH=−9.5+1.7 x Ngr. (for branch)

     
  2. 2.

    Plant biomass has been found to increase with age. The period of most rapid increase is between 44–46 growth rings.

     
  3. 3.

    The net above ground biomass in this tree species has been computed to be 6101 kg/ha.

     
  4. 4.

    The average increment in non-photosynthetic above ground biomass has been observed to range between 0.32 to 5.5 kg/tree/yr.

     
  5. 5.

    Comparison of biomass production in this tree species has been made with other tropical forests tree species of comparable age and the possible causes of difference in biomass production are discussed.

Zusammenfassung

Diese Abhandlung berichtet über Pflanzen-Biomasse und Netto-Produktion vonButea monosperma. Das beobachtete Gebiet des Borimalan-Forstes auf den Prasad-Hügeln liegt 54 km südlich der Stadt Udaipur (24°11′N und 73°42′E). Aus der vorliegenden Studie ist folgendes zu entnehmen:
  1. 1.

    Eine klare positive Beziehung zwischen der Zahl der Jahresringe von Stamm und Ästen und ihrem CBH (Brusthöhenumfang) wurde beobachtet. Die erhaltenen Regressionsgleichungen sind: CBH=35,8+0,37 x Ngr. (für Stamm) CBH=−9,5+1,7 x Ngr. (für Äste)

     
  2. 2.

    Es wurde festgestellt, daß die Pflanzen-Biomasse mit dem Alter zunimmt. Die größte Zuwachsperiode liegt zwischen 44–46 Jahresringen.

     
  3. 3.

    Die oberirdische Netto-Biomasse bei dieser Baumart errechnet sich auf 6101 kg/ha.

     
  4. 4.

    Der durchschnittliche Zuwachs an nicht photosynthetischer Biomasse über dem Boden bewegt sich zwischen 0,32 bis 5,5 kg pro Baum und Jahr.

     
  5. 5.

    Es wurden Vergleiche zwischen dieser Baumart und anderen tropischen Waldbaumarten mit vergleichbarem Alter angestellt und die möglichen Ursachen des Unterschiedes in der Produktion an Biomasse wurden besprochen.
