บทคัดย่อ (EN): Hevea brasiliensis, the perennial tree species, belonging to the family Euphorbiaceae is the major source of Natural Rubber. Latex is harvested from the bark through the process of controlled wounding called tapping at specific angles based on the orientation and inclination pattern of laticiferous system. A detailed investigation on the inclination of laticifers in ten clones of Hevea brasiliensis with special emphasis on the interrelationship and influence of various bark structural characters on the alignment and orientation of laticifers and other phloic elements was made. The clones selected includes Tjir 1, GI 1, PB 86,GT 1, PB 28/59, RRII 105, RRIM 600, RRIM 703, PB 235 and RRII 300 at an age of 17-21 years. Seedling progenies of two Wickham x Amazon cross combinations (RRII 105 x MT 1005; RRIM 600 x AC 495) and bud grafted plants of RRII 105 and RRIM 600 were also studied at the age of 4 years to understand the inclination pattern of laticifers in the immature growth phase. The present study revealed that there was clonal variation in the direction of inclination of latex vessels. In six clones viz. RRIM 703, GI 1, RRII 300, Tjir 1, PB 235 and GT 1 the laticifers and phloic rays were inclined towards the right whereas in PB 86 the inclination was towards the left. In three clones viz. RRII 105, PB 28/59 and RRIM 600 the laticifers were inclined towards both directions. In the immature phase, the seedling progenies of the cross combinations showed rightward inclination of laticifers and phloic rays. The young budded plants of RRII 105 showed rightward inclination whereas those of RRIM 600 showed both right and left ward inclination. About 90% of the laticifers were distributed contiguous to phloic rays. Regression analysis indicated that various independent variables were positively and negatively associated with the dependent variable, laticifer inclination. In general, the inclination of phloic rays has been identified as the most influential positive factor on laticifer inclination. The significance of orientation and inclination of latex vessels on direction and angle of tapping cut in the context of realization of potential yield of different clones is discussed.
