“…Regarding the laticifer structure, they have been stained conventionally with Sudan III, Sudan IV, or Oil red O, and have been observed using light microscopy (Wimalaratna 1973;Richardson 1983;Hamzah et al 1988;Omman and Reghu 2003). Diagrams of the three-dimensional structures in H. brasiliensis bark have been obtained based on observations using light microscopy (Riches and Gooding 1952;Fahn 1979;Nicole et al 1986). These show that laticifers are arranged in concentric layers in the bark.…”

In Hevea brasiliensis, laticifers produce and accumulate rubber particles. Despite observation using histochemical methods, development stage structure and structures with ceasing functions have rarely been described. Spectral confocal laser scanning microscopy with Nile red staining simplifies laticifer structure observation in tangential sections while enhancing the resolution. Laticifer and ray images were extracted from unmixed images and used to monitor changes during growth. A laticifer network structure developed from increased anastomoses between adjoining laticifers outside of the conducting phloem, but because of increased radial division and growth of rays, the network structure ruptured and disintegrated. We also investigated immunohistochemical localization of two rubber particle-associated proteins in the laticifers: small rubber particle protein (SRPP) and rubber elongation factor (REF). Mature bark test results show that SRPP is localized only in the laticifer layers in the conducting phloem; REF is localized in all laticifer layers. Because SRPP plays a positive role in rubber biosynthesis, results show that the rubber biosynthesis capability of laticifers is concentrated where rays and the sieve tube actively transport metabolites.

“…In the previous papers of this series (Riches & Gooding, 1952;Gooding, 1952a) various aspects of the problems associated witb the effect of tapping on the latex of Hevea brasiliensis have been considered. It is desirable now, in conclusion, to consider tbe whole field covered in this series and to present the general picture that emerges, which is as follows:…”

P a d a k o n d i s i pertumbuhan yang normal dan proses penyadapan yang baik, jumlah pembuluh lateks pada kulit pulihan lebih banyak dibandingkan kulit perawan (Riches & Gooding, 1952;Webster & Paardekooper, 1989).

Penyadapan yang tidak benar akan menghasilkan kulit pulihan yang buruk dan rendah produksinya. Beberapa alternatif sistem sadap perlu diteliti antara lain aplikasi stimulan, sistem sadap ganda, dan irisan sadap pendek. Tujuan penelitian ini adalah untuk mengetahui pengaruh beberapa alternatif sistem sadap terhadap karakter fisiologi, pertumbuhan, dan produksi klon BPM 24. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Sembawa, menggunakan klon BPM 24, dan rancangan acak kelompok dengan 6 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa irisan ganda (S/4 U d3 ET2.5% Ga1 9/y (m) + S/2 d3 dan S/4 U d3 ET 2.5% Ga1 9/y (m) + S/4 d3 ET2.5% 9/y (m)) tidak mampu meningkatkan produksi dibanding sistem konvensional (S/2 d3). Kombinasi antara irisan pendek dan stimulasi justru menurunkan produksi karet kering. Irisan ganda menurunkan kadar karet kering (KKK) dan pertumbuhan lilit batang.
