Study curried out to evolution response growth and biochemical of Ocimum basilicum L. under drought conditions. Plant grown under treatment conditions (24 hours with - 54°C, 21°C, 55-70% RH) and plant were transferred to growth chamber for 6 weeks. The results showed that the rate of increase in chlorophyll a and b was significant with an increase rate of 1.7 and 0.6 compared to control after three days of treatment. The results also showed that H2O2 content was increased and reached to 1.3, 2.8 and 3.5X compared to the control after three, six and nine days of treatment respectively. One the other hand the levels of the enzyme APX activity, Lipid peroxidation and protein which was conducted on the tissue of basil leaves, increase compared with control after three days of treatment.

This synthesis and characterization of slow release material from epoxidized natural rubber (ENR) and rice husks (RH) composites was conducted. The alkali modification of rice husks was carried using different NaOH concentration. ENR-50 and RH composites were analyzed by FTIR. Furthermore, the release behavior of the composites was invistigated using UV-visible spectroscopy. From the purified ENR-50, it can be characterized the peak epoxide group identified at 875 cm-1 and for the isoprene at 835 cm-1. For RH/urea beads, the CH2 peak of cellulose was obtained at 1457 cm-1. However, the CH2 is overlapped with cellulose at 1741 cm-1 and 1726 cm-1 that resulted for the partial opening of epoxide ring from carbonyl peak for hemi-cellulose and lignin, there are C=C stretching from aromatic group can be obtained at 1512 cm-1 and 1595 cm-1. The release of the composite at 7% NaOH concentration was higher than the composite at 1% NaOH concentration.

In this research, the effects of Rice Straw (RS) reinforced Standard Malaysian Rubber (SMRL) on curing characteristics, tensile properties and physical properties were investigated. All compounds were prepared using two roll mill at five different RS loading (10, 20, 30, 40, 50 phr). In addition, two different size of RS, fine size (FS) at 300 μm and coarse size (CS) at 10 mm were used. The properties such as cure characteristics, tensile properties and physical properties were determined. Results indicated that the fine size of RS filled SMRL contributed to the better properties such as tensile, hardness and crosslink density compare to coarser size of RS filled SMRL at same loading.
