Conteúdo: |
The effects of moisture content, temperature, and storage on secondary dormancy were studied in two sizes of loblolly pine seed from two sources, Kemper County, Mississippi and Jasper County,Texas. Moisture content and temperature were the most important factors in inducing secondary dormancy. Length of storage did not strongly influence the percentage of dormant seed. Secondary dormancy was induced by reducing moisture content to 13% or less and/or by exposing seed to temperatures of 23oC or higher for 48 hours. Both seed sources and seed sizes reacted in a similar to treatments used to induce secondary dormancy. |

To identify superior genotypes, 42 progenies of interspecific hybrids
between American oil palm and oil palm were evaluated in an area with incidence
of bud rot. The following variables were assessed: total bunch yield
(TBY), number of bunches (NB) and mean bunch weight (MBW) from the third
to the sixth year of cultivation and estimates of genetic parameters obtained
by REML/BLUP procedures. High heritability values of the evaluated traits were
observed. The gain estimates for TBY were 14.49% for the selection of the five
best progenies and 33.36% for the selection of the five best trees, considering
multiplication by cloning. A medium correlation was observed between TBY and
NB (r2 = 0.33±0.021), a high correlation between TBY and MBW (r2 = 0.53±0.019)
and a negative high correlation between NB and MBW (r2 = ?0.60±0.018). The
results indicate a high expectation of gains with selection for TBY. |
