To investigate the effects of cadmium (Cd) stress on the growth of different tomato rootstocks, the Cd content and transport efficient of rootstocks, the pot experiment was carried out with wild eggplant rootstocks Solanum torvum and Totosga, tomato rootstock “Dalishengen”, “Banzhen18” and “Guozhen1”. Under Cd stress, the plant heights of “Banzhe18” and “Dalishengen” were significantly higher than other; the main root lengths of Totosga and S. torvum were significantly longer than other. The dry weight of the “Banzhen18” was the highest, and the “Guozhen1” was the smallest. The order of Cd content in roots was S. torvum > Totosga > “Guozhen1” > “Banzhen18” > “Dalishengen”; the content of Cd in the stem of “Dalishengen” was the highest, and Totosga was the least. The order of Cd content in leaves was “Guozhen1” > “Dalishengen” > “Banzhen18” > Totosga > S. torvum. S. torvum had the smallest translocation factor, and “Dalishengen” had the biggest. Cd stress showed significant inter-specific differences in rootstock growth and Cd content. The plant height of tomato rootstock was significantly higher than the wild eggplant rootstock, and the main root length of wild eggplant rootstock was significantly longer than tomato rootstock. The Cd contents in S. torvum and Totosga mainly accumulated in the roots, so the Cd content in the aerial part was much lower than other.

Trace metals (TM) contamination is a severe problem in the environment and produced an adverse effect on the productivity of crops. Cadmium (Cd) is a TM ranked seven among the top 20 pollutants due to its high toxicity and solubility in water, taken up by the plants and affects their growth and metabolism. In this study, we evaluated the growth, Cd accumulation and tolerance capacities of three chickpea (Cicer arietinum L.) cultivars (NC234 (NC2), ICCV89310 (IC8) and ICCV89323-B (IC8-B)), subjected to two Cd concentrations (25 and 50 µM) in hydroponic culture. The toxicity of Cd reduced the plant height and fresh and dry biomass in all cultivars. The maximum reduction was observed at 50 µM of Cd. Compared with IC8-B, cultivars IC8 and NC2 exhibited better performance with high growth, biomass, root to shoot (R/S) ratio and water content under high Cd stress. To measure the accumulation of Cd in root and shoot, an inductively coupled plasma optical emission spectrometer (ICP-OES) was used. IC8 and NC2 had comparatively high Cd tolerance and accumulation ability (> 100 µg g−1 dry weight), with IC8 being more tolerant and accumulated higher Cd in shoot than NC2, while cultivar IC8-B was sensitive. Root accumulated more Cd than shoot in a dose-dependent manner. The bioconcentration factors (BCF) and bioaccumulation coefficients (BAC) were far higher than one (> 1) and increased with an increase in Cd concentrations, while the translocation factor (TF) was less than one (< 1), suggesting that all the three cultivars were unable to transfer Cd from the root to the shoot efficiently. Our results indicated that IC8 and NC2 proved to be resistant, while IC8-B showed sensitivity when exposed to high Cd stress (50 µM).

Pot experiment was conducted in a randomized complete block design with three replication and six treatments in the screenhouse of Soil Science Division, Khumaltar during the year 2003 and 2004. The objective of the experiment was to find out the effect of vermicompost in combination with or without soil and mineral fertilizers on the yield and other attributes of chickpea. The results showed an encouraging effect of vermicompost application on the plant height, root length and biomass dry weight of chickpea when vermicompost was applied in equal ratio with soil (5 kg each/pot) and 10:20:15 kg N: P2O5:K2O kg ha-1. Vermicompost with equal ratio of soil (5 kg each/pot) also produced the highest mean grain yield of 10.6 gm per pot. However, no significant treatments effects were observed for root length and straw weights of the chickpea.Nepal Agric. Res. J. Vol. 9, 2009, pp. 49-55DOI: http://dx.doi.org/10.3126/narj.v9i0.11641

The availability of water is one of the most important factors for the development of the seeds. Thus, studies related to adequate humidity&nbsp;for germination, emergence and early development of safflowers, is necessary for the productive use of this culture. Thus, the objective of study was to evaluate the initial development of two varieties of seeds of Safflowers (IAPAR and IMA2103) in six levels of water availability in substrate: 0, 10, 20, 30, 40 and 50%. At 15 days the seedling emergence were evaluate. At 30 days were evaluate plant height, root length, stem diameter, number of leaves, fresh weight of the aerial part and root, dry weight of shoot and root. The treatment without irrigation, there was decrease the emergence, emergence speed for both genotypes. Treatments above 30% of water availability in the two varieties presented emergency superior to 50%. Lower irrigation rates favored root length and dry mass.

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.

Roots represent the fundamental structure and material transport systems in plants. These important organs are used to study the adaptation processes in the environment. During the nursery stage, root evaluation serves as determining the seedling quality before transplant. This research aims to ascertain the root characteristics of several Arabica coffee varieties for a suitably vigorous root nursery system. Kaliwining Experimental Garden, Jember, Indonesia, served as the research location. The method used was a completely randomized design with a single factor, including arabica coffee varieties (Abesinia-3, Andungsari-1, BLP-4, Gayo-1, K-08, K-29, K-34, K-79, K-130, Kartika-1, Kayumas and Sigararutang). The result showed that the differences in the various sample factors significantly influenced the root properties. In addition, the entire observation parameters demonstrated a positive correlation except for the root and shoot ratio. Furthermore, BLP-4 v obtained the maximum values for plant height, stem diameter, fresh dry weight of taproot, and root biomass, while Gayo-1 variety observed the greatest number of leaves. Also, the Sigararutang variety indicated the highest value of the fresh and dry weight of shoot, fresh weight of lateral roots, and root length, while Kayumas and K-34 varieties acquired the lowest values of plant height, fresh and dry weight of shoot and root, as well as root length. Therefore, BLP-4, Gayo-1, and Sigararutang varieties exhibited the potentials of broader adaptability.

The objective of this work was to evaluate the effect of grafting (onto Solanum torvum Sw.) on plant growth, yield and fruit quality of the Pala and Faselis eggplant (Solanum melongena L.) cultivars, grown in a soil infested with Verticillium dahliae Kleb. and Meloidogyne incognita, or in noninfested soil. Soil infestation decreased yield, plant height, final above-ground biomass, and also reduced fruit mean weight and shoot dry weight depending on cultivar or grafting. Grafting decreased fruit oxalic acid and the soluble solid contents, and increased mean fruit weight, depending on cultivar and soil infestation. Grafting also reduced the negative effects of the pathogens on disease index, plant height and shoot dry weight. Cultivar Pala was more vigorous than Faselis, and S. torvum was a vigorous rootstock. The combination of a vigorous rootstock with a weak cultivar (Faselis) is more profitable than that of a vigorous rootstock and a vigorous cultivar (Pala). Using S. torvum as a rootstock for cultivar Faselis, grown in soil infested with the pathogens, is most likely to be useful in conventional and low-input sustainable horticulture, since grafting increases protection against the pathogens, and reduces the losses in quality and yield.

The biomechanical root flexibility in response to hydromechanical soil heterogeneity is the most determining factor of the root architecture which plays a paramount role in mycorrhizal infection and allows the seedlings to adapt to the environmental constraint. We examined the impact of five different hydromechanical medium properties (hydroponics, vermiculite, vermiculite-gravel, sawdust, and sand) on the morphology, physiology, and anatomy of Cedrus atlantica seedlings at a controlled growth chamber. The growth of the seedling is strongly stimulated by the hydroponic medium through the stimulation of the aerial part dry weight and the main root length. However, the sand medium increases the main root dry weight by the radial expanse stimulation at the level of the epidermis, vascular cylinder, and cortex and compensates the less root architecture by the stimulation of the xylem and phloem areas. In contrast to sand and hydroponic media, the sawdust medium stimulates the phloem/xylem ratio, the root architecture, and the short roots. The Pearson bilateral correlation shows that the aerial part dry weight is positively correlated with the permeability, porosity, and water-holding capacity and negatively with the bulk density and density at saturation, whereas the short root production is negatively correlated with the permeability and water-holding capacity. Hence, the hydromechanical characteristics of the soils must be taken into account in the reforestation and mycorrhization attempts.

This study aims to determine the differences in the growth response of green curly lettuce to the differentiation treatment of LED lighting with different spectrum in indoor hydroponics. The research was conducted from October to November 2017. The experimental design used was experimental with 1 lighting factor with 5 levels, there are sunlight (P0), LED 20% blue: 80% red (P1), LED 80% blue: 20% red (P2), 50% blue LED: 50 % red (P3), and 100% white daylight (P4). Observational variables included plant height, leaf number, leaf area, leaf color, total wet weight, leaf wet weight, wet root weight and dry weight of the plant. The result of this experiment showed that LED irradiation have affect the treatment are plant height, leaf number, leaf area, chlorophyll content, fresh weight of harvest, root length, and dry weight of brackets. While those that have no significant effect are the wet weight of the roots. The results showed that between LED irradiation treatment L1, L2, L3, and L4 showed that treatment L2 with 80% blue spectrum composition: 20% red showed better growth based on: high plant, chlorophyll content, and root length. Treatment with L4 with white LED showed better growth based on the number of leaves, leaf area, fresh weight of harvest, root wet weight, and dry weight of total biomass. The results below the sunlight better than the LED irradiation treatment, because the intensity of LED far low and lack of controlled environmental conditions technology and management for growing lettuce. In all of LED treatment still looked etiolation because light intensity was not optimal yet.
