| Summary, etc | A correlation study on ten Hevea brasiliensis clones showed that the factors detrimental to girth increment on tapping favours the occurrence of tapping panel dryness. Laticifer area index was an exception which has positive association with both. The number of latex vessel rows, the number of intraxylary phloem groups and total volume of latex produced together contributed to 49 per cent variation in the occurrence of tapping panel dryness of which the two structural traits alone governed 39 per cent variation. The associations of characters indicated that a very high number of latex vessel rows in high yielding clones leads to high incidence of tapping panel dryness. Hence selection based on high girth, good quantity of intraxylary phloem and balanced number of latex vessel rows is suggested for sustainable yield by reducing TPD> The two structural traits mentioned above are useful parameters for early prediction of clonal susceptibility to TPD at least to some extent. The importance of laticifer area index and number of intraxylary phloem groups as selection parameters is discussed. |
