Tperformance of 15 clones of the IAC 500 series of Hevea brasiliensis, developed at Instituto Agronômico (IAC), over a 12-year period, in the northwest region of São Paulo State, Brazil. The 15 new clones evaluated are primary clones obtained from selected ortets within half-sib progenies. The clone RRIM 600, of Malaysian origin, was used as the control. Dry rubber yield performance over a four-year period, mean girth at the tenth year, girth increment before and during tapping, thermal properties of the natural rubber produced and other characters of the laticiferous system were evaluated. Forty percent of the clones were superior in comparison to the control for yield. Clone IAC 500 recorded the highest yield (66.81 g per tree per tapping) over four years of tapping, followed by IAC 502 (62.37 g per tree per tapping), whereas the control recorded 48.71 g per tree per tapping. All selected clones were vigorous in growth. The natural rubber from this IAC clones showed thermal stability up to 300ºC. No differences were observed in the thermal behavior of rubber among the IAC series and the RRIM 600 clones. The clones IAC 500, IAC 501, IAC 502, IAC 503 and IAC 506 are the more promising for small-scale plantations, due to growth and yield potential. |

The objective of this study was to evaluate height-diameter, volumetric, and taper models to estimate tree height and volume to describe the bole profles of a eucalypts clone established in three agrosilvopastoral spatial arrangements (18×2.5; 5×2+40; 3 (3×2)+30) in Coronel Xavier Chaves, Minas Gerais state, Brazil. The diameter at breast height, total height, and diameter outside bark along the stems of the sample trees were collected. Height-diameter, volume, and taper models were ft to the observed data for each spatial arrangement and were compared to select the best alternative. The mean annual increment for single, double, and triple lines at 48, 60, and 72 months of age, respectively, ranged from 26.0 to 34.6 m3 ha?1 year?1, as well as individual volume ranged from 0.41 to 0.53 m3 tree?1. The heightdiameter curves showed a distinct tendency for each spatial arrangement and can be represented by diferent equations. The equations to estimate volume and taper ft well to the data, and the Spurr and Garay models were selected as the best ftting, respectively. In addition, Graybill's F-test (Theory and application of the linear model. Duxbury Press, Massachussetts, 1976) showed that a single equation could ft the Spurr and Garay models for all spatial arrangements. |
