Field experiment showed that Mn contents in various organs of kenaf (Hibisus canna-binus ) varied in the following sequences, lower leaf>middle leaf>upper leaf>root>skin>stalk. The absorbed Mn was mainly present in leaves before the fiber accumulation stage. After this stage, the absorbed Mn was used for the development of stem. Ultrasection revealed that Mndeficient chloroplast tended to be expended in volume and round in shape, with the increase in its strama material. The grana were disorganized...

Field experiment showed that Mn contents in various organs of kenaf (Hibisus canna-binus ) varied in the following sequences, lower leaf>middle leaf>upper leaf>root>skin>stalk. The absorbed Mn was mainly present in leaves before the fiber accumulation stage. After this stage, the absorbed Mn was used for the development of stem. Ultrasection revealed that Mndeficient chloroplast tended to be expended in volume and round in shape, with the increase in its strama material. The grana were disorganized and its thylakoid membrance was poorly developed or even absent. Application of Mn increased the chla, chlb contents, the chl a/b ratio, and the CO2 assimilation rate. It stimulated the activity of nitrate-reducing enzyme, the synthesis of protein and nucleic acid, and the uptake and utilization of nitrogen, and affected the differentiation and development of stem fiber cells. Application of Mn fertilizer ( MnSO4·H2O ) 1.0 kg per mu ( in Mn deficient soil ) increased the yield of kenaf by 28.8%.

研究结果表明,红麻(Hibisus cannabinus)各器官的含锰量是下位叶>中位叶>上位叶>麻根>麻皮>麻秆。麻株吸收的锰在形成纤维盛期前主要集中于叶部,尔后主要用于茎的发育。由超显微切片观察到,缺锰叶的叶绿体膨胀变圆,体积增大、衬质增多,各基粒排列混乱,膜系统发育不良,甚至瓦解。砂培试验中施用锰肥可增加叶片叶绿素a和b的含量及叶绿素a/b比值,可提高CO_2同化率和提高叶片硝酸还原酶的活性,促进蛋白质和核酸的生物合成及对氮的吸收和利用,还影响茎纤维细胞的分化和发育。对缺锰土壤施用锰肥(MnSO_4·H_2O)1.0kg/666m~2,可使红麻增产28.8%。

An experiment was conducted using 320 day-old Arbor Acres(l/2 male, 1/2 female) to investigate the Mn optimal level of broilers fed a basal cornsoybean meal diet supplemented with reagent grade MnSO4· H2O in cages for 28 days. The basal diet contained 16ppm Mn and the experimental diets contained 36, 56, 76, 96, 116, 136 and 156ppm Mn. The chicks fed 96ppm Mn diet had the highest weight gain (P>0.05). Incidence of leg abnormality declined from 57.5% of the chicks fed the basal Mn deficient...

An experiment was conducted using 320 day-old Arbor Acres(l/2 male, 1/2 female) to investigate the Mn optimal level of broilers fed a basal cornsoybean meal diet supplemented with reagent grade MnSO4· H2O in cages for 28 days. The basal diet contained 16ppm Mn and the experimental diets contained 36, 56, 76, 96, 116, 136 and 156ppm Mn. The chicks fed 96ppm Mn diet had the highest weight gain (P>0.05). Incidence of leg abnormality declined from 57.5% of the chicks fed the basal Mn deficient diet to below 10% of the chicks fed the diets containing 116ppm Mn or higher. Mn concentrations of liver, pancreas, kidney, heart, spleen and muscle, and Mn-containing superoxide dismut-ase(MnSOD) activity of heart were well fitted into the corresponding curve models(quadratic curves or asymptotes) with dietary Mn contents (P<0.001), while Mn concentration in bone ash was increased linearly (P<0.01). And dietary Mn contents required to reach the plateau of Mn concentrations of the above mentioned soft tissues and to obtain the maximum MnSOD activity of heart were calculated to be 110, 111, 141, 123, 109, 99 and 121ppm respectively. However, MnSOD of live and pancreas were not affected(P>0.05). For broilers fed this basal corn-soybean meal diet, 120ppm Mn is suggested as the satisfactory level, which doubles the presently recommended requirement.

用一日龄Arbor Acres雏鸡320只(1/2,1/2(?)),分成8组,分别喂以含锰(Mn)16ppm的玉米-豆饼基础饲粮和含Mn36、56、76、96、116、136和156ppm的添加Mn(试剂级MnSO_4·H_2O)饲粮28天,研究笼养肉仔鸡饲粮Mn的适宜水平。随饲粮Mn的提高,鸡体重在96ppm时增至最大(P>0.05),腿病发生率由57.5%(缺Mn基础组)逐渐降至10%以下(116ppm以上组);骨灰中Mn的含量呈线性上升(P<0.01),但肝、胰、肾、心、脾和肌肉中Mn的含量及心脏含Mn超氧化歧化酶(MnSOD)活性可与饲粮Mn含量拟合成相应的渐近线或二次曲线模式(P<0.01),当这些软组织Mn达到平衡和心MnSOD活性达最高时,计算所需的饲粮Mn分别为110、111、141、123、109、99和121ppm;肝和胰MnSOD无明显变化(P>0.05)。由上建议:AA肉仔鸡在0~4周龄饲粮中Mn含量以120ppm为宜,即为我国现行肉仔鸡Mn建议需要量60ppm的2倍。

180 day-old Arbor Acres (AA) chicks (1/2, 1/2) fed a basal corn-soybean meal diet supplemented with reagent grade MnSO4.H2O for 28 days. The basal diet contained 18ppm Mn and the experimental diets contained 50, 90, 130, 280 and 2840 ppm Mn. As dietary Mn levels increased, bodyweight gain of chicks was up to the maximum at 90ppm Mn (P>0.05) and then down to the minimum at 2840ppm (P< 0.05) with a similar trend for feed intake (P<0.05 or 0.01) and feed conversion (F/G) was not changed...
