Salinity is one of most significant environmental stresses. Marigold is moderately tolerant to salinity stress. Therefore, in this study, the fresh weights of roots and shoots, rootFW/shootFW ratio, moisture content of shoots, micronutrient and macronutrient concentrations and ratios of K+/Na+ and Ca2+/Na+ in the roots and shoots of marigold were determined under salinity stress. Five salinity treatments (0, 50, 100, 150, and 200 mM NaCl) were maintained. In the current study, salinity affected the biomass of marigold. An increase of more than 100 mM in salt concentrations significantly reduced the shoot fresh weight. Increasing salinity stress increased the ratios of rootFW/shootFW, which were more significant under high salt levels (150 and 200 mM NaCl). Wet basis moisture contents of the shoots were reduced when salinity stress increased above 100 mM. In this study, salinity stress affected micronutrient and macronutrient uptake. Increases in the salt concentration and decreases in the concentration of Cu2+ and Zn2+ in the roots and Mn2+ and Fe2+ in the shoots were significant. Based on an increase in salinity stress, while the Ca2+, Mg2+, and Na+ concentrations increased, the K+ concentration decreased in the roots and shoots. Moreover, the K+/Na+ and Ca2+/Na+ ratios of the roots and shoots were significantly lower than those of the control in all of the salinity treatments. As a result, under increasing salinity stress, the Ca2+, Mg2+, K+, and Na+ uptakes in marigold were significant, revealing the effects of stress.

Based on the investigation and integrated assessment of the growth rapidity,adaptability and resistibility(especially the cold tolerance) tests of 3 eucalyptus clones,Eucalyptus camaldulensis(Min'an-9),E.urophylla × E.grandis(DH32-29) and E.grandis, the biological and ecological traits of the three eucalyptus clones were carried out.The results showed that Eucalyptus camaldulensis(Min'an-9) was suitable to plant on the mountains under the altitude of 500 m,E.urophylla × E.grandis(DH32-29) grew fastest and was suitable to plant on the mountain near the seaside under altitude of 300 m,and E.grandis had better growth rapidity,adaptability and resistibility and could be the main species to establish short-rotated industrial material eucalyptus forest.

Abstract: This study evaluated the potential for development in the greenhouse, cuttings of the hybrid of Eucalyptus grandis x Eucalyptus camaldulensis in Sinop - Mato Grosso and generated equations to estimate the percentage of rooting parameters. Were measured: the percentage of cuttings with some degree of modification, the percentage of cuttings in the percentage of cuttings with roots larger than 10 cm in length. Also measured was the neck diameter, height and leaf area index. The heights and leaf area showed lower development within the greenhouse. The rooting potential is based on curve speed of rooting and was found 12 days after staking. The identification of the optimal point of withdrawal of the shoots of the greenhouse through the intercept curves daily current increase curve (DCI) e daily average increase (DAI), being 19 days after staking. The company derives the stakes with 24 days underdoing the potential of the species and structures used. Keywords: Eucalyptus, greenhouse management and rooting

The objective of this study was to evaluate the behavior of three hybrids of the genus Eucalyptus and Eucalyptus camaldulensis cultivated at Fazenda Buritis, Sorriso municipality, Mato Grosso State, Brazil, using DAP, height, bark volume, IMA, stem quality and survival. It was done a DIC, distributing 4 plots of 343m2, 49 trees per plot, in each of the 4 cultivated materials in a spacing of 3.5 x 2m, and 3 data collections were carried out, from January 2013 to January 2014 The results show that clones I144 and H13 have higher mean DAP, height, volume with IMA bark, higher percentage of trees with straight stem and higher survival rates indicating that the soil and climatic conditions of the city of Sorriso-MT are presented as suitable for the cultivation of these genetic materials

Eleven eucalyptus species are characterized for morphological, chemical, pulp and paper-making characteristics to get high pulp yield of good strength through social forestry in north Indian topological conditions. Eucalyptus grandis of Bhadrachalam and Saharanpur origins give very good fibre dimensions, especially slenderness ratio, which is directly comparable to Pinus kesiya. Other eucalyptus species have shorter fibres and narrow lumen with thick wall resulting to poorer flexibility, higher Runkel ratio and rigidity coefficient. The chemical analysis of eucalyptus species reveal satisfactory levels of holocellulose (except Eucalyptus camaldulensis) and Klason lignin content ( 25%) lignin content except E. ‒413 (hybrid) might require additional pulping time and chemical charge compared to other species. Kappa number ( 48%) and higher strength properties of E. grandis of Bhadrachalam and Saharanpur origins, Eucalyptus torrelliana, Eucalyptus camaldulensis and Eucalyptus alba showed their suitability for social forestry.

Essential oils obtained by hydrodistillation of Eucalyptus camaldulensis and Eucalyptus grandis from Hatay (Turkey), were analyzed by GC/MS. The total ratio of twenty-three components in Eucalyptus camaldulensis volatile components with 98.15%. This ratio is seen as forty-seven components and 99.66% in Eucalyptus grandis. Eucalyptol, limonene and α-pinene were identified as the main components of the essential oils of Eucalyptus camaldulensis. Cymene, α-pinene, isoborneol, trans-pinocarveol and eucalyptol were identified as the main components of the essential oils of Eucalyptus grandis. When compare the components of E. camaldulensis and E. grandis essential oils, the main component was determined as eucalyptol with 74.11% and cymene with 31.67% respectively.

Abstract This study was undertaken to examine the effects of NaCl and Na 2 SO 4 salinity on the growth of carrot ( Daucus carota L.) and the concentrations of essential and nonessential elements in the shoots and storage roots determined by polarized energy dispersive x‐ray fluorescence (PEDXRF). Both types of salinity reduced plant growth, but growth reduction in NaCl salinity was more pronounced. Na concentrations in shoots and roots were increased by salinity treatment. The concentration of Cl was also increased by NaCl salinity. Salinity treatments decreased K concentrations in the shoots and storage roots, and Ca concentrations in the shoots. Concentration of P in shoots and roots, and S, Mg, and Si in roots were not significantly affected by salinity treatments, while the NaCl salinity reduced S and Si and increased Mg concentrations in the shoots. Fe, Zn, Mn and Mo concentrations in the shoots were not significantly affected by salinity treatments. In the storage roots, the concentration of Fe was significantly increased by NaCl salinity, while Na 2 SO 4 salinity significantly increased Zn and Mn concentrations in storage roots. Concentration of Al in the storage roots was significantly higher with NaCl treatment than with Na 2 SO 4 treatment. Ni concentrations in the shoots were strongly increased by NaCl salinity, while concentrations of Br in the shoots and storage roots were significantly reduced by NaCl salinity. Rb concentrations in shoots and storage roots were significantly reduced by Na 2 SO 4 salinity, but not by NaCl salinity. Concentration of Cs in the shoots was increased by both types of salinity, but Cs concentration of the roots was increased by Na 2 SO 4 . Concentration of Ba in the shoots was lowered by Na 2 SO 4 treatment, while it was increased in the roots by Na 2 SO 4 salinity. Salinity did not affect the Ce concentration in the shoots but increased it in the storage root, and NaCl salinity increased U concentration in the roots of the carrot plants.
