The absorption of Cu(2+), Zn(2+), and Mn(2+) by leaf tissue of 4-month old sugarcane plants (Saccharum officinarum L., var. H53-263) has been investigated. After the "apparent free space" fraction was desorbed, the absorption of Cu(2+), Mn(2+), and Zn(2+) yielded a curve typical of many ion uptake processes when measured as a function of the external concentration. However, only 1 absorption me...

The quantification of soil water balance components was conducted in a sugarcane (Saccharum officinarum L.) field differently managed, as well as a qualitative analysis of the methodologies used for their estimation. The study was conducted in randomized block experiment with four replicates and three treatments: bare soil, mulched soil using trash left on the soil surface after harvest, and so...

The phenolic acids found in graminaceous plant cellwalls are esters with sugars and lignin.1 ~3) Previously, we separated two feruloylated oligosaccharides from an enzymatic hydrolysate of the bagasse lignin-carbohydrate complex.4'5* As an extension of the structural elucidation of phenolic-acid-containing oligosaccharides, we now describe the isolation and identification of a new tetrasacchari...

Simultaneous quantitative analysis of 10 indole compounds, including indole-3-acetic acid (IAA, one of the most important naturally occurring auxins) and some of its metabolites, by high performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) after solid-phase extraction (SPE) was reported for the first time. The analysis was carried out using a reverse phas...

cDNA fragments of lea3 genes with a high GC content (from 68 to 77%) were found in several Poaceae, including Sorghum vulgare, Saccharum officinarum, Oryza officinalis, Oryza meyeriana, Ampelocalamus calcareus, Cynodon dactylon, and Zizania latifoli. They were successfully isolated by means of optimal experimental parameters, which included dimethyl sulfoxide as additive and degenerate primers ...

The research of silica gel manufacturing from cane pulp cinders (Saccharum Officinarum) and the application for Cu (II) ion adsorption has been done. done by some variaties, such as pH, concentration, contact time. result shows optimum pH was 8, concentration 8 ppm, time 75 minutes. perecentage recovery 90,28%, effectivity can be applicated ion.
