Clonal and Planting Density Effects on Some Properties of Rubber Wood (hevea Brasiliensis Muell. Arg.)
Inter-clonal and intra-clonal wood properties and their variations from pith to bark were evaluated for wood density and anatomical features on rubber wood (Hevea brasiliensis Muell. Arg) from a 9-year-old plantation with planting densities of 500 and 2000 trees per hectare comprised of clones RRIM 2020 and RRIM 2025. Planting density had uneven effects on wood density and wood cell features. I...
متن کاملDiversity of fungal endophytes in leaves and stems of wild rubber trees (Hevea brasiliensis) in Peru
Endophytic fungi isolates from foliage and sapwood of Hevea brasiliensis were studied to determine the total diversity of endophytes inhabiting leaves and sapwood, and differences between respective endophyte communities found in leaves and sapwood. Endophytes were recovered from 72 % (161) of the 225 samples, with a total of 175 isolates. Sequence data from ITS and LSU nrDNA revealed 58 distin...
متن کاملStudies on Rubber (Hevea brasiliensis) Trees Exist Plant Type after Planting and Available Tapping Tree of Rubber Plantation in China
Existing plant types of rubber tree after planting and available tapping tree were investigated, and there were about 28 rubber plantations with different tapping years of 8 varieties “CATAS7-33-97”, “CATAS8-79”, “CATAS7-20-59”, “PR107”, “RRIM600”, “GT1”, “INA873”, “93-114” in South China. The results showed that there were six kinds of existing plant types of rubber tree after planting of rubb...
متن کاملinteraction effects of general combining ability and specific combining ability with environment in virginia tobacco genotypes
to evaluate the effect of environment on the general and specific combining ability of virginia tobacco genotypes, five varieties were intercrossed in combination in 2007 in a half – diallel design. in 2008, the ten f1 population and the five parental lines were sown in two different conditions (drought stress and non-stress) using a complete randomized block design with three replications and ...
متن کاملRepeatabilty of general and specific combining ability effects of seedling and clonal generations in potato
The relative magnitude of general combining ability (gca) and specific combining ability (sca) effects in three generations (years), viz. Seedling (SG), first clonal generation (FCG) and second clonal generation (SCG) for tuber yield, tuber number, average tuber weight and tuber dry matter of potato in a line x tester mating design (10 × 4) was studied. There were marked differences in the gca ...
