Heavy metal zinc is one of the trace elements necessary to the growth of vegetable, but Zn excessiveness also could cause damage. In this research, four vegetables were planted by soil culture method under different Zn2+concentration controlled by the exogenous Zn2+addition; their growth characteristics were analyzed to find the sensitive growth indexes to Zn and compare their tolerance to Zn pollution. Results show that: low concentration of Zn2+(< 100 mg/kg) can promote significantly the plant height and the root length growth of all the four vegetables, while, as the exogenous Zn2+increased to the concentration of 150 mg/ kg, the number of leaves, the above-ground dry biomass and the underground dry biomass were suppressed significantly; in this experiment, the four vegetables appeared different sensitivity to Zn stress,Lactucasativavar.longifoliafappeared highest tolerance andBrassicachinensisappeared less sensitivity to Zn stress.

Sage and mountain sage belong to Lamiaceae family which have commercial importance from medicinal and aromatic plants in Turkey. The aim of this study was to evaluate the effects of different doses of selenium in salinity conditions on the morphological characteristics of sage (Salvia officinalis L.) and mountain tea (Sideritis sp.). Four different doses of selenium (5, 10, 20, 40 mg/l) were applied in without salinity (0) and salinity (250 mM NaCl/l) medium. The experiment was carried out in the split plot design with three replications in the climate chamber room of the department of field crops. When the examined properties were evaluated; plant height changed between 15.56-23.85 cm, number of branches 10.50-12.78 number/plant, number of leaves 52.78-92.00 number/plant, fresh leaf weight 2.48-7.51 g/plant, dry leaf weight 0.48-3.32 g/plant, fresh root weight 1.52-7.16 g/plant, dry root weight 0.19-1.24 g/plant, root length 26.18-36.07 cm, fresh shoot weight of 1.13-7.15 g/plant and dry shoot weight 0.13-0.38 g/plant. In mountain tea, the properties were determined for plant height as 3.26-5.93 cm, for number of branches as 2.50-6.33 number/plant, for number of leaves as 28.22-91.14 number/plant, for fresh and dry leaf weights as 2.42-11,03 and 0.45-1.91 g/plant, for fresh and dry root weights as 0.71-3.97 and 0.18-0.74 g/plant, for root length as 14.78-33.26 cm, for fresh and dry shoot weights as 0.29-2.28 and 0.12-0.41 g/plant were determined. As a result of this study, 5 mg/l selenium application in salinity conditions in both plants has reached high values in terms of fresh leaf weights. In addition to this, it was found that selenium applications in salinity conditions had positive effects on dry leaf weight in sage and fresh root and fresh shoot weights in mountain tea. As a result of correlation analysis, positive correlations were found between dry leaf weight and other characteristics especially in mountain tea in terms of traits examined in both plants.

PGPR (Plant Growth Promoting Rhizobacteria) is a substance that helps plant growth with the help of rhizosphere microorganisms. PGPR propagation can be done with liquid media. This PGPR propagation needs to be done because this substance has many benefits for agricultural cultivation. The application of PGPR to the test plant, namely the pakcoy plant, proved that there was an effect of giving PGPR to the plant. Observations on the test plants were carried out by observing several observation variables such as plant height, root length, number of leaves, wet weight and dry weight. The results of these observations showed that the effect on the test plants was seen in the variables of root length, wet weight, and dry weight. Meanwhile, the variable plant height and number of leaves did not show a visible difference.

In this study, rooting and growth characteristics of different poplar clones from six species including Populus deltoides Bartram ex Marshall clone Lux, Populus nigra subsp. betulifolia (Pursh) W. Wettstein clone 17/13, Populus euramericana (Dode) Guinier clone 561/41, P. deltoides clone Samsun, Populus alba Linnaeus clone 49/9, Populus caspica (Bornmüller) Bornmüller, and Populus euphratica Olivier in hydroponic and soil cultures have been evaluated. In hydroponic culture, poplar cuttings were grown in plastic tanks and in soil culture, poplar cuttings were planted into plastic pots with 12 replications for each clone. The pot experiment was a Complete Randomized Design. Root length, stem diameter, stem height, and root and shoot dry matter of poplar plants were studied in hydroponic culture after 84 days and in soil culture three times at 6, 12, 18 weeks in 2017. In hydroponic culture, the cuttings of P. deltoides Lux and P. nigra betulifolia 17/13, and of P. deltoides Samsun and P. euphratica were among the first and last clones that rooted, respectively. Also, the lowest rate of rooting was observed in P. deltoides Samsun and P. euphratica clones. The highest values of all parameters except root length were obtained in P. euphratica. The highest root length and stem diameter were observed in clones of P. deltoides Lux, P. nigra betulifolia 17/13, P. euramericana 561/41, and P. deltoides Samsun. In soil culture, P. deltoides Lux, P. nigra betulifolia 17/13, and P. alba 49/9 showed the highest percentage of rooting compared to the other clones at the first measurement. All the clones except the clone of P. euphratica reached above 40 cm root length in each of the three measurement periods. The highest stem diameter, stem height, and shoot dry matter were obtained in clone of P. deltoides Lux and root dry matter in clone of P. alba 49/9.

Our objective was to investigate the influence of alternative substrates based on stem decomposed by babassu and humic substances in the production of sunflower seedlings. The experimental design was randomized blocks, in a 3 x 4 factorial scheme (substrate x humic substances). Twelve treatments were studied, T1 (100% babassu stem decomposed (BDS) + 0 ml L-1 HS), T2 (100% BDS + 12.5 ml L-1 HS), T3 (100% BDS + 25 ml L-1 HS), T4 (100% DBS + 50 ml L-1 HS), T5 (50% DBS + 50% LAd + 0 ml L-1 HS), T6 (50% DBS + 50% LAd + 12, 5 ml L-1 HS), T7 (50% DBS + 50% LAd + 25 ml L-1 HS), T8 (50% DBS + 50% LAd + 50 ml L-1 HS), T9 (100% LAd + 0 ml L-1 HS), T10 (100% LAd + 12.5 ml L-1 HS), T11 (100% LAd + 25 ml L-1 HS) and T12 (100% LAd + 50 ml L-1 HS). Each treatment was performed in four replications with one seedling per plot, totaling 48 plots. The DBSxHS interaction provided increases in root length, root volume, basal diameter, number of leaves, plant height and parameters related to inflorescence. The substrate with 100% decomposed babassu stem, together with the dose of 12.5% humic substance, is the best option for producing 'IAC Uruguay' sunflower seedlings. Further research on the use of DBS and HS is needed to address the use and purpose in producing new crops.

The aim of this study was to determine the concentration and exposure time to NaCl suitable for the micropropagation of banana, through the analysis of growth traits. Banana propagules were inoculated in MS medium with different concentrations of NaCl (0; 50; 75 and 100 mM) for 120 days (multiplication and rooting, 60 days each), with monthly subcultures. These propagules were measured for plant height, number of leaves, sprouting rate, average number of formed propagules, rooting rate, root length and survival rate. After 30 days, NaCl reduced sprouting rate at multiplication; the number of leaves, rooting rate and root length in rooting; and the height and propagules number in both phases. After 60 days, the NaCl affected the sprouting rate and propagules number in the multiplication; length of root in rooting; and the height and number of leaves in both phases. After 120 days, the reduction in the survival rate was proportional to the increase of NaCl in the medium. Thus, it is concluded that NaCl reduces most of the growth traits and the treatments with 75 and 100 mM NaCl affected multiplication and in vitro rooting more intensely.

ABSTRACT ‘Pitaya’ (Hylocereus undatus) is a fruit-bearing, climbing cactus with great food potential for the semiarid region. This study aimed to evaluate the production of ‘pitaya’ seedlings irrigated with low and high salinity water and grown in different light intensities. The experiment was conducted in a completely randomized design, in a 2 × 2 factorial arrangement, with two electrical conductivities of irrigation water: S1 - 0.3 dS m-1 (low salinity) and S2 - 5.0 dS m-1 (moderate salinity) in two environments: A1 - black net with 50% shading, and A2 - full sun, with ten replicates. The variables evaluated were plant height, main cladode diameter, above-ground biomass, root biomass, total plant biomass, number of secondary cladodes, root length, and length of secondary cladodes. The 50% shading (black net) promoted higher plant height, number of secondary shoots, and root length of the ‘pitaya’ plants. The irrigation with moderate saline water (5.0 dS m-1) reduced the number of secondary cladodes, length of root, and length of secondary cladodes. The ‘pitaya’ seedlings grown under 50% shading (black net) showed greater root dry biomass when irrigated with low-salinity water. Greater values of diameter of the primary cladode, above-ground dry biomass, and total dry biomass were observed under full sunlight and elevated saline stress.
