Indonesia’s target to be a new industrial country makes a wide chance in the developing of many industrial sectors. The main problem is the disruption of environmental balance due to poorly managed liquid waste released by the industry. Heavy metal such as chromium (Cr) is the typical pollutant generated from tannery industry in Indonesia. Toxicity test of desorbed chromium ions from polluted soil around tannery industry in Yogyakarta-Indonesia by using Brassica junceaand Helianthus annuus L.has been carried out. In this research, soil samples were dividedinto four sample points based on the distances from the waste water point sources. Metal content and some physico-chemical properties including ash content, total organic carbon, and cation exchange capacity were determined in this study. Furthermore, the chromium ions adsorption and desorption from polluted soils were investigated and measured by atomic adsorption spectrophotometry (AAS). Thus, ecotoxicity testsof soil eluates from desorption experiments wereperformed with Brassica junceaand Helianthus annuus L.The resultsshowed that sample III had the highestCr content at916mgkg–1.The adsorption isotherm of Cr ions into soils followed Langmuir isotherm with the highest maximum adsorption capacity value at 14.286 mg kg-1in the sample point IV (unpolluted soil). The optimum desorption of chromium occurred at pH 3. Toxicity test showed that Cr ions had toxic effect to Brassica junceaand Helianthus annuus L.

Sunflowers ((Helianthus annuus L) is a plant that has the ability to absorb metals in polluted soil or environment. This study aims to determine the ability of sunflower plants to absorb lead (Pb) in the soil. This research method use a Completely Randomized Design (CRD). Pb metal analysis was carried out by testing the lrvels using the Atomic Absorption Spectrophotometry (AAS) tool in the Chemical Laboratory (LABKES). The results showed that the highest absorption of Pb contamination in P2L2 treatment (2.0 ppm) as much as 5.04 ppm and the lowest absorption of metals in the treatment P1L1 (0.3 ppm) yielded as much as 0.52 ppm Pb metal content. From the results of these studies it can be concluded that sunflower plants can be used as phytoremediation pf Pb metal.

SUMMARY Seed germination of six sunflower (Helianthus annuus L.) hybrids was investigated across a range of eleven constant temperatures between 5°C and 45°C. Large temperature differences in germination rate 1/t (d-1), cardinal temperature (°C) and thermal time θ (°cd) were observed among hybrids. Base temperatures (Tb) varied between 3.3°C and 6.7°C whereas maximum germination temperatures (Tm) varied between 41.7°C and 48.9°C. Final germination fraction was attained at 15°C - 25°C whereas the maximum rate of germination was attained at 30.4°C - 35.6°C. The maximum germination rate of hybrid USDA 894, the cultivar with the slowest germination rate, was only 50% of that of hybrid EX 47. The low Tb and high Tm of sunflower appear to be one of the factors which explain the successful adaptation of sunflower to a wide range of temperature. These findings are discussed in relation to the origin of the crop and its wide adaptations in diverse habitats and climatic zones.

SUMMARYA field experiment was conducted at Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bangalore to study the effect of irrigation regimens on the biomass accumulation, canopy development, light interception and radiation use efficiency of sunflower. The treatments includes irrigating the plants at 0.4, 0.6, 0.8 and 1.0 cumulative pan evaporation. The results indicated that the aboveground biomass, canopy development, radiation interception and radiation use efficiency were influenced favorably by the irrigation regimens. Irrespective of the irrigation regimen, the radiation use efficiency of sunflower increased from 15 DAS to 75 DAS and then tended to decline. The decrease in RUE after anthesis is coupled with decrease in leaf nitrogen content. In general the RUE of sunflower ranged from 0.49 g MJ-1 to 1.84 g MJ-1 at different growth stages. The light transmission within the canopy increased exponentially with plant height and the canopy extension coefficient is found to be 0.8.
