Waterlogging and restricted-below ground aeration on photosynthetic performance and root elongation rate of RRIM 600 and RRIT 251 rubber genotypes (Hevea brasiliensis Mull. Arg.)

نویسندگان

چکیده

Due to extended inundation, waterlogging and restricted below-ground aeration cause inhibition in plant growth performance. This study examined two different rubber clones, RRIM 600 RRIT 251, for below ground aeration. To evaluate the performance under stress conditions, net photosynthetic rate (PN), maximum quantum yield photosystem II (Fv/Fm) root elongation were observed. has a higher normal conditions. However, PN Fv/Fm ratio trend showed that seems have difficulties recovering after exposure restricted-below Although 251 had lower tendency of this clone fast recovery. also performed both conditions than 600.

Proteomics analysis of latex from Hevea brasiliensis (clone RRIM 600).

The natural rubber latex extracted from the bark of Hevea brasiliensis plays various important roles in today's modern society. Following ultracentrifugation, the latex can be separated into 3 layers: C-serum, lutoids, and rubber particles. Previous studies have shown that a large number of proteins are present in these 3 layers. However, a complete proteome for this important plant is still un...

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...
