“…However, the fast-growing nature of Acacia auriculiformis and its good adaptability in degraded soil condition, especially in saline soils, it has been considered a priority species in the short-rotation plantations in Bangladesh, such as social forestry and agroforestry projects in the coastal belts (Islam et al, 2007. It is a fast growing nitrogen fixing multipurpose tree species which prevents exposure of soils to direct radiation from the sun using its perennial foliage as well as crown cover, and reduce the evaporation rate, resulting in less salt accumulation in the top soils (Tham & Liew, 2012;Khan et al, 2014;Sohel et al, 2016). Furthermore, it is extensively used to provide shade, form windbreaks, and the wood has been used widely for charcoal, fuel, pulp, tool handles, oars, paddles, packing cases, and furniture manufacturing (Shukla et al, 2007;Chowdhury et al, 2013).…”

Aim of the study: To evaluate the morpho-physiological changes of Acacia auriculiformis in response to seawater induced salinity stress along with its tolerance limit.Area of study: Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh. Material and methods:Three saline treatments (4, 8, 12 dS m -1 ) were applied to six-month aged Acacia auriculiformis seedlings from January 2014 to June 2014 and the tap water was used as control treatment. To observe salinity effects, the following parameters were measured by using various established techniques: plant height and leaf number, plant biomass, shoot and root distribution as well as shoot and root density, water uptake capacity (WUC), water saturation deficit (WSD) and water retention capacity (WRC), exudation rate, and cell membrane stability.Main results: Diluted seawater caused a notable reduction in shoot and root distribution in addition to shoot and root density, though plant height, leaf number and plant biomass were found to be decreased to some extent compared to control plants. Water status of the plant also altered when plants were subjected to salinity stress. Nevertheless, membrane stability revealed good findings towards salinity tolerance.Research highlights: Considering the above facts, despite salinity exerts some negative effects on overall plant performance, interestingly the percent reduction value doesn't exceed 50% as compared to control plants, and the plants were successful to tolerate salinity stress till the end of the experiment (150 days) through adopting some tolerance mechanisms.Keywords: Salt stress; halophytes; growth parameters; WUC; exudation rate; membrane stability.

“…From this study, it has been observed that soil amended with different concentrations of MI can also improve the seedling growth of forest crops. Mridha (2005), Khan (2012) and Khan et al (2011Khan et al ( , 2014) also reported enhanced seed germination rate and seedling growth with the application of low concentrations of MI. Specially, applying 2% of MI enhanced seed germination and seedling growth at an optimum level which might be due to the presence of microbial population in such a density within this concentration which was cable to produce optimum level of growth enhancing hormones and other chemicals.…”

“…The total dry biomass increased gradually with the increase of the concentrations of MI up to 2% while decreased gradually from its maximum point as the concentrations of MI increased above 2%. Increased biomass production might be due to the better root development in the treated seedlings (Khan et al, 2011(Khan et al, , 2014. Such promotion might also be due to the biological active substances in the inoculant (Lim et al, 1999), such as indole acetic acid (IAA) and gibberellins produced by Lactobacillus spp., Rhodopseudomonas spp., Aspergillus spp.…”

“…Specially, applying 2% of MI enhanced seed germination and seedling growth at an optimum level which might be due to the presence of microbial population in such a density within this concentration which was cable to produce optimum level of growth enhancing hormones and other chemicals. However, as the concentration of MI increased, seed germination and seedling growth was depressed, which may be due to the perniciousness exerted by the higher concentrations of the inoculant (Mridha, 2005;Khan et al, 2014).…”

“…The nodule dry weight increment rate was positive for 0.1%, 0.5%, and 1% of MI while negative for all other treatments, with respect to control ( Table 3). The number of nodule in soybean root was also not changed significantly due to application of low concentrations of MI (Thach et al, 1999) while decreased in higher concentrations in Dalbergia sissoo and Acacia auriculiformis (Khan et al, 2011(Khan et al, , 2014. The higher concentrations of MI solution in the substratum may affect the growth of plants because of toxic effect of secretion of toxic metabolites.…”

Microbial inoculants (MI), a biofertilizer, composed of many different beneficial microorganisms has positive role on seed germination and growth of plants. In the present study, its efficacy on seed germination and seedling growth of Albizia lebbeck in the nursery was studied. The seeds were sown in polybags filled with a mixture of forest soil and cow dung (3:1) and treated with 0.1%, 0.5%, 1%, 2%, 5% and 10% concentrations of MI. Most of the parameters studied (seed germination, shoot and root lengths, dry weights of shoot and root, collar diameter, leaf number etc) were found maximum in 2% of MI . Although the highest vigor index, volume index and quality index (7053, 3738 and 1.106, respectively) were found in 2% MI, but the highest sturdiness (65.95) was found in 1% MI solution. The nodule number was higher at a very low (0.5%) concentration of MI but it normally decreased with the increase of concentration. Total pigment content in leaf was recorded highest (112.86 mg.L -1 ) in 2% of MI. Therefore, MI influences seed germination and seedling growth of A. lebbeck and the low concentration (2%) of the inoculant can be recommended for getting maximum seed germination and seedling growth of the species studied. , is a moderate to large deciduous tree with a straight bole and broad crown under the family Leguminosae (Mimosoideae). The species is widely spread in the world, and is native to Asia, Africa and Northern Australia. It grows naturally in Nepal, Bangladesh, Myanmar and Pakistan and has been cultivated in tropical and subtropical regions in Northern Africa, the West Indies, South America, and south Asia. Extensive plantations had been established in Nepal and in South India (Luna, 1996;Kumar et al., 2010;Elzaki et al., 2012;Missanjo et al., 2013). The wood is excellent for furniture and timber for general uses, post, piles, fuel wood and charcoal. The tree is used as ornamental and nurse tree for tea gardens, coffee and cocoa orchards (Mishara et al., 2010;Missanjo et al., 2013;Shaikh et al., 2014). It is a soil improver because of its inherent ability to fix nitrogen (Qadri and Mahmood, 2005). The leaves are excellent fodder for livestock. The species is also very useful for the rehabilitation of degraded lands because of its rapid growth, ability to fix nitrogen and tolerance for a range of soil conditions (Luna, 1996;Qadri and Mahmood, 2005;Mishara et al., 2010;Bobby et al., 2012;Shaikh et al., 2014). The plant has already been proven successful for afforestation, reforestation, social forestry and agroforestry programs in Bangladesh (Zabala, 1990;Dey, 2006).To fulfill the high demand, many organizations are producing A. lebbeck seedlings in the nursery in Bangladesh to supply those in the plantation programs. Because the plants are grown mostly in unfavorable soil conditions, beneficial soil microorganisms can play a significant role in early establishment and better growth of the inoculated seedlings under field conditions. The microbial inoculant (MI) in this study, with the commercial name "Effe...
