      Abstract
      Penelitian bertujuan untuk mengetahui variasi musiman karakter fisiologi tanaman karet akibat pemberian etepon, dan hubungan antar karakter fisiologi dengan produksi lateks. Penelitian dilaksanakan di Bogor, Jawa Barat (250 m dpl) mulai September 1997 hingga Desember 1998. Percobaan dalam dua faktor perlakuan, yaitu delapan klon karet (AVROS 2037, BPM 24, PR 261, RRIM 712, GT 1, BPM 1, PR 228, dan LCB 1320) dan tiga sistem eksploitasi (& = '/z S d/2, El = '/z S d/3.ET2.5%, E2 = '/z S d/3.ETS.O%). Peubah yang diamati adalah produksi lateks, indeks penyumbatan, kadar karet kering, %-KAS, pH lateks, kadar sukrosa, kadar fosfat anorganik, kadar tiol, aktivitas SOD, produksi etilen, kadar ACC, aktivitas ACC-oksidase; dan protein dalam fraksi serum-C dan lutoid Hasil penelitian menunjukkan bahwa perlakuan stimulasi meningkatkan produksi lateks pada empat klon (PR 261, BPM 24, PR 228, dan AVROS 2037).
       
      The objectives of the study were to determine the seasonal variation of physiological characters of hevea by ethephon application, and the relationship among physiological characters influencing latex production. The experiment was carried out in Bogor, West Java (250 m above sea level) from September 1997 to December 1998.
