Base values or critical limits were fixed for latex diagnosis (LD) parameters in clone RRII 105 under the recommended tapping system 1/2S d/3 which ensures an optimum yield in the BO-1 and BO-2 panels. The critical limits fixed were used for assessing the exploitation status of smallholdings and for optimising stimulation schedules in clone RRII 105. Latex diagnosis studies conducted under different exploitation systems revealed that negative aspects of intensive tapping and over stimulation could be detected by changes in the levels ofLD parameters from their threshold levels. Based on the levels of latex diagnosis parameters and yield under 1/2S d/3 tapping system the production metabolism of RRII 105 is characterised as active. The production potential of RRII 105 with its high metabolic activity and low sugar reserve limit its ability to respond to hormonal stimulation. In RRII 105 an increase in yield is not obtained beyond five stimulations a year under d/3 or d/4 tapping systems.

Abstract

Base values or critical limits were fixed for latex diagnosis (LD) parameters in clone RRII 105 under the recommended tapping system 1/2S d/3 which ensures an optimum yield in the BO-1 and BO-2 panels. The critical limits fixed were used for assessing the exploitation status of smallholdings and for optimising stimulation schedules in clone RRII 105. Latex diagnosis studies conducted under different exploitation systems revealed that negative aspects of intensive tapping and over stimulation could be detected by changes in the levels ofLD parameters from their threshold levels. Based on the levels of latex diagnosis parameters and yield under 1/2S d/3 tapping system the production metabolism of RRII 105 is characterised as active. The production potential of RRII 105 with its high metabolic activity and low sugar reserve limit its ability to respond to hormonal stimulation. In RRII 105 an increase in yield is not obtained beyond five stimulations a year under d/3 or d/4 tapping systems.
