| 2 | Improving Acacia auriculiformis seedlings using microbial inoculant(Beneficial Microorganisms)显示文摘A microbial inoculant, known as effective microorganisms(EM), was applied to determine its efficacy on seed germination and seedling growth in the nursery of Acacia auriculiformis A Cunn. ex Benth. The seedlings were grown in a mixture of sandy soil and cow dung(3:1) and kept in polybags; EM was poured at different concentrations(0.1%, 0.5%, 1%, 2%, 5% and 10%). Seed germination rate and growth parameters of seedlings – shoot and root lengths, fresh and dry weights of shoots and roots, vigor, volume, and quality indices and sturdiness – were measured. The nodulation status influenced by EM was also observed, along with the measurement of pigment contents in leaves. The highest germination rate(72%) was observed in 2% EM solution while the lowest(55%) was found in control treatment. The highest shoot and root lengths(30.6 cm and 31.2 cm respectively) were recorded in 2% EM and were significantly(p <0.05) different from control. Both fresh and dry weights of shoots were maximum(8.66 g and 2.99 g respectively) in 2% EM, whereas both fresh and dry weights of root were maximum(2.56 g and 1.23 g respectively) in 5% EM solution. Although the highest vigor index, volume index, and sturdiness(4450, 628 and 67.5 respectively) were found in 2% EM, the highest quality index(0.455) was found in 5% EM solution. The nodule number was higher at a very low(0.5%) concentration of EM but it normally decreased with the increase of concentration. The contents of chlorophyll a, chlorophyll b, and carotenoid were maximum(43.26 mg?L-1, 13.56 mg?L-1and 17.99 mg?L-1 respectively) in 2% EM. Therefore, low concentration of EM(up to 2%)can be recommended for getting maximum seed germination and seedling development of A. auriculiformis in the nursery. | Bayezid M.Khan M.K.Hossain M.A.U.Mridha | 2014 | Journal of Forestry Research2014，25，2： | 2 |
| 3 | Assaying the allelopathic effects of Eucalyptus camaldulensis in a nursery bed incorporated with leaf litter显示文摘Allelopathic effects of Eucalyptus camaldulensis Dehnh. were confirmed in Petri dish and pot experiments in our previous studies. However, the degree to which such effects under controlled experiments exist in more complex ecological settings remains to be tested. Thus, the present study was carried out by incorporating different proportions of ground litter of E. camaldulensis in soil. The growth of three agricultural crops: falen(Vigna unguiculata(L.) Walp.), chickpea(Cicer arietinum L.), and arhor(Cajanus cajan(L.) Millsp.), and two tree species, kala koroi(Albizia procera(Roxb.) Benth.) and ipil ipil(Leucaena leucocephala(Lam.) de Wit) were tested. There were inhibitory effects of leaf litter on germination, shoot and root growth, leaf number, and collar diameter as well as a reduction of nodulation by legume crops(25–80%reduction). The extent of the effects was dependent on the proportion of leaf litter, the species and the type of traits. In contrast to shoot growth, the effect on root growth was more severe. No effect on germination was found with the agriculture crops while the two tree species showed reduced germination. The effect was greater in the presence of higher proportions of leaf litter mixed in soil while in some cases lower proportions stimulated growth. Not all species were suppressed; A. procera, C. cajan, V. unguiculata showed compatible growth while C. arietinum and L.leucocephala were found incompatible. This study provides evidence that E. camaldulensis has allelopathic potential under field conditions and a careful selection of associated crops in agroforestry systems is highly recommended. | Romel Ahmed Mohammad Shafioul Alam Farid Uddin Ahmed M.K.Hossain | 2018 | Journal of Forestry Research2018，29，3： | 2 |
| 4 | Nursery practice on seed germination and seedling growth of Dalbergia sissoo using beneficial microbial inoculants显示文摘Nursery practice using microbial inoculants was performed to find out the efficacy of the inoculants on seed germination and seedling growth of sissoo(Dalbergia sissoo Roxb.).Microbial inoculants or effective microorganisms(EM) are a mixture of many different beneficial microorganisms in a solution.The seedlings were grown in a mixture of sandy soil and cowdung(3:1) kept in polybags with pouring EM solution at different concentrations(0.1%,0.5%,1%,2%,5% and 10%) before and after a week of sowing the seeds.Seed germination rate and growth parameters of seedlings were measured,such as,shoot and root length,vigor index,fresh and dry weight of shoot and root and total biomass increment.The nodulation status influenced by EM was also observed along with the measurement of pigment contents in leaves.The highest germination rate(69%) was observed in 2% EM treatment,followed by 67% and 65% in 1% and 5% EM.The highest shoot length(33.2 cm) was in 2% EM,whereas highest root length(26.3 cm) was in 1% EM.Both fresh and dry weights from shoot and root,were maximum(4.16 g and 1.57 g;2.12 g and 0.83 g respectively) in 2% EM and were significantly(p ≤ 0.05) different from control.Vigor index was highest(4071) in 2% EM,which was significantly(p ≤ 0.05) different from control.Total dry weight increment was highest in 2% EM treatment,followed by 1% and 5% concentrations of EM.Nodulation number was higher at very low(0.1%) concentration of EM solution but it normally decreased with the increase of EM concentrations.The contents of chlorophyll a,chlorophyll b and carotenoid were highest(60.11,17.05 and 42.48 mg·L1respectively) in 2% EM treatment and lowest(39.35,13.55 and 27.29 mg·L-1 respectively) in control treatment.Therefore,low concentration of EM(up to 2%) can be used for getting maximum seed germination rate and seedling development of Dalbergia sissoo Roxb. | B.M.Khan M.K.Hossain M.A.U.Mridha | 2011 | Journal of Forestry Research2011，22，2： | 1 |

| 6 | 有效微生物群对雨豆树发芽率和苗木生长的影响(英文)显示文摘雨豆树的苗木种植在容器袋的沙和牛粪的混合质上(3:1)。在播种前后一周施用不同浓度(0.1%, 0.5%, 1%, 2%, 5% and 10%)的有效微生物群(Effective Microorganisms )液。测定发芽和苗木自然生长参数(包括:茎根长度,活力指数,直径,叶子数量,茎根的鲜重和干重,总的生物量增长量)。估计生化参数如叶绿素 a, 叶绿素 b,类胡罗卜素,并观测了受有效微生物群影响的生节情况。与对照相比, 经不同浓度有效微生物群液处理的雨豆树,发芽率和苗木自然生长参数都明显增加。施用 2%有效微生物群液的苗木生长率最大,其次是施用 1%有效微生物群液的苗木。1%有效微生物群液的生节率最高,并随浓度的增加而下降。尽管经有效微生物群液处理的苗木叶中色素比对照高,但叶绿素 a, 叶绿素 b,类胡罗卜素并不明显高于对照。随着有效微生物群液浓度的增加,苗木生长表现出不同的效果,大部分参数在中等浓度范围最高。研究表明,有效微生物群技术有助与提高苗圃中苗木的生长,有益微生物与容器袋土壤相结合有助于改善退化的或贫瘠的土壤,有利于初移植苗木的营养和水分吸收。表 4 参 17。 | B.M.Khan M.K.Hossain M.A.U.Mridha | 2006 | Journal of Forestry Research2006，17，2： | 1 |
| 7 | Allelopathic effects of Mikania cordata on forest and agricultural crops in Bangladesh显示文摘Mikania cordata, an invasive weed is becoming a problem in the secondary degraded forests and plantations of Bangladesh, not only competing with but also releasing allelochemicals to cultivated crops. Allelopathic effects of the leaves of M. cordata were investigated through an experiment in the green house of the Institute of Forestry and Environmental Sciences, University of Chittagong, Bangladesh. Five economically important agricultural crops(Oryza sativa L., Triticum aestivum L., Vigna sinensis L., Abelmoschus esculentus L. and Amaranthus tricolor L.) and three forest crops(Acacia auriculiformis A.Cunn. ex Benth. & Hook, Albizia procera(Roxb.) Benth.,and Paraserianthes falcataria(L.) Nielson) were used as bioassay species. Experiments were conducted on trays at an average room temperature 27 °C. The effects of different concentrations of leaf extracts were compared to controls. Water soluble allelochemicals of M. cordata inhibited the germination and initial growth of the tested agricultural and forest crops. Germination percent of forest crops declined with increasing concentration of extracts.The inhibitory effect on root elongation of forest crops was pronounced, whereas a stimulatory effect was found on P.falcataria up to a concentration of 25 %. Abelmoschus esculentus showed poor germination(%) and low shoot development(0.5 cm) and no development of taproot or lateral roots at treatment of 100 % concentration. Theinhibitory effect was proportional to the concentrations of the extracts with higher concentrations producing stronger inhibitory effects. Lower concentrations showed some stimulatory effect. The inhibitory effect was pronounced in root and lateral root development rather than germination or shoot development of the crops. Mikania cordata should be eradicated for healthy growth and development of the forest and adjacent agricultural crops. | M.K.Hossain S.Anwar R.Nandi | 2016 | Journal of Forestry Research2016，27，1： | 1 |
| 8 | Pre-sowing treatments for improved germination and growth of two rare native species of Bangladesh显示文摘Pre-sowing treatments are expected to increase seed germination.This evaluates response to pre-sowing treatments and the growth performance of two native and rare tree species,Garuga pinnata Roxb.and Vitex glabrata R.Br.The hard seed coats were treated by rubbing with sand paper,nail clipping,and immersion in water and acid(H_2SO_4).Results indicate that G.pinnata showed a 90% germination rate and 30% germination energy when seed coats were nicked with a nail clipper.Rubbing with sand paper was the best pre-sowing treatment for V.glabrata,resulting a 80% germination rate and 30% germination energy.G.pinnata and V.glabrata seedlings from seeds soaked 24h in water resulted in maximum heights and collar diameters.These were significantly higher(at p<0.05) than those of other treatments.The results indicate that scarification or nicking of seeds may have some negative impacts on seedling growth.Therefore,it is difficult to recommend a pre-sowing treatment of seeds for achieving both maximum germination and good early seedling growth. | M.A.Hossain K.S.Islam N.Rajasree M.K.Hossain M.S.Alam | 2018 | Journal of Forestry Research2018，29，5： | 0 |
