Abstract. Singh RK, Malik N, Singh S. 2013. Impact of rhizobial inoculation and nitrogen utilization in plant growth promotion of maize (Zea mays L.). Nusantara Bioscience 5: 8-14. During the course of growing population demands, there has been an increasing interest in exploring the possibility of extending the beneficial interaction between cereals and plant growth promoting rhizobacteria (PGPR). Endophytes are a group of microorganism that resides mostly in the intercellular space of various parts of plants including cereals. Assessment of plant growth promoting properties of the five-rhizobial strains belonging to ? subclass i.e. Rhizobium leguminosarum bv. phaseoli RRE6 and R. undicola RRE36 and those belonging to ? subclass i.e. Burkholderia cepacia (RRE3, RRE5, RRE25) was done by growing maize plants inoculated with these strains. Inoculated maize plants showed a significant increase in plant height, root length, shoot and root dry weight over uninoculated control. R. leguminosarum bv. phaseoli RRE6 and B. cepacia RRE5 among the ? and ?-subclass representatives respectively, gave the best inoculation response. Effect of nitrate supplementation upon maize-RRE6 and RRE5 association was also studied and a significant increase in all the growth parameters and colonization ability was recorded when nitrate was present as a supplement over uninoculated control and maize-RRE6 and RRE5 in absence of external nitrate.

Abstract. Kumar R, Tapwal A, Pandey S, Borah RK, Borah DP, Borgohain J. 2013. Macro-fungal diversity and nutrient content of some edible mushrooms of Nagaland, India. Nusantara Bioscience 5: 1-7. The northeast region of India abounds in forest wealth, including variety of flora and fauna. The high humidity during monsoon period provides ideal atmospheric conditions for the growth of diverse group of macrofungal fruit bodies. Nagaland, the northeastern state of India is rich in biodiversity and encompasses large numbers of edible and non-edible mushroom species. Young and matured carpophores of 15 wild edible mushroom species were collected from 12 locations in different districts of Nagaland. Out of these four species belongs to family Agaricaceae, two belongs to Tricholomataceae and rest belongs to Boletaceae, Cantharellaceae, Russulaceae, Sarcoscyphaceae, Auriculariaceae, Polyporaceae, Schizophyllaceae, Pleurotaceae, and Lyophyllaceae. The selected species were analyzed for proximate analysis of nutritional values. The protein content varies from 22.50-44.93% and carbohydrates were recorded 32.43-52.07% in selected species. The documentation of wild edible mushrooms is very scanty in Northeast India. The key objective of the present study was to generate a database on macrofungal diversity, ecology, ethnomycology, utilization and nutrient status of important wild edible mushroom species of Nagaland, which forms a part of the food culture of the native peoples.

Abstract

Khalid KA. 2013. Effect of nitrogen fertilization on morphological and biochemical traits of some Apiaceae crops under arid region conditions in Egypt. Nusantara Bioscience 5: 15-21. Arid regions in Egypt are characterized by poor nutrients content and unfavorable environmental conditions which negatively affect growth and productivity of medicinal and aromatic plants including anise, coriander and sweet fennel. So the main objective of the present investigation was to study the effect of different levels of N, namely 0 (control), 100, 150 and 200 kg ha-1 used as ammonium sulphate [(NH4)2SO] (20% N), on selected morphological and biochemical characteristics of anise, coriander and sweet fennel plants cultivated under arid regions conditions during two successive seasons. The most effective dose of nitrogen was 200 kg ha-14 of N, resulting in a positive increase in vegetative growth characters and content of essential oil, fixed oil, total carbohydrates, soluble sugars, protein and nutrients (NPK).

Abstract. Hendawy SF, Hussein MS, Youssef AA, El-Mergawi RA. 2013. Response of Silybum marianum plant to irrigation intervals combined with fertilization. Nusantara Bioscience 5: 22-29. This study was investigated to evaluate the influence of different kinds of organic and bio fertilization under different irrigation intervals on the growth, production and chemical constituents of Silybum marianum plant. Data indicated that all studied growth and yield characters were significantly affected by the duration of irrigation intervals. Fertilizer treatments had a primitive effect on growth and yield characters. The interaction between irrigation intervals and fertilizer treatments has a clear considerable effect on growth and yield characters. The obtained results indicated the favorable effect of organic and bio fertilizers which reduce the harmful effect of water stress. Different treatments had a pronounced effect on silymarin content.

Abstract. Zoghi Z, Azadfar D, Khazaeian A. 2013. Study of altitude and selection on fiber biometry properties of Fagus orientalis Lipsky. Nusantara Bioscience 5: 30-34. This research reports to the influence of altitude above sea level and selection on fiber biometry of beech wood (Fagus orientalis Lipsky). In this research, six trees in 550 MASL (three plus trees and three non-plus trees) and six trees in 850 MASL (three plus trees and three non-plus trees) were selected. One sample from each tree was gotten with increment borer at breast height. Fiber characteristics such as fiber length, fiber diameter, lumen width, and two wall thicknesses were measured in Franklin method. Slenderness ratio, flexibility ratio and rankle ratio were estimated. The results showed that the altitude had a significant effect on fiber length, lumen width, wall thickness, and biometry coefficients. Tree quality has a significant effect on fiber length, lumen width, and wall thicknesses and biometry coefficients. Fiber length, lumen width, slenderness ratio and flexibility ratio in plus trees were more than non-plus tree.

Abstract. Ammar MSA, Ashour F, Abdelazim H. 2013. Coral disease distribution at Ras Mohammed and the Gulf of Aqaba, Red Sea, Egypt. Nusantara Bioscience 5: 35-43. Six sites along the Gulf of Aqaba and Ras Mohammed, Red Sea, Egypt were studied for coral disease distribution relative to environmental stress. These sites are (i) South Taba, (ii) South Nuweiba, (iii) Canyon, (iv) Eel Garden (at Dahab), (v) Shark Observatory and (vi) Yolanda. Number of coral diseases ranges from 6 diseases at site 4 (Eeel Garden) to 12 diseases at site 3 (Canyon). The site having the lowest number of coral diseases (site 4) is characterized by the highest percentage cover of coral diseases (24%). The coral disease atramentous necrosis attained the highest percentage cover in all sites (5, 5, 6, 6, 2 and 3%) in sites 1-6 respectively. A total of 16 diseases were reported being distributed in the following order in sites 1-6: 9, 9, 12, 6, 8 and 7 respectively. The coral disease atramentous necrosis is the most widely distributed one being found in all 6 sites followed by dark spots disease and ulcerative white spots being reported in 5 sites. The disease that is least distributed is the white tips being reported in site 5 only. The most commonly distributed disease (atramentous necrosis) infected six corals in site 1, two corals in site 2, nine corals in site 3, two corals in site 4, five corals in site 5 and five corals in site 6. However, the least commonly distributed disease (white tips) infected only two corals (Acropora humilis and Millepora dichotoma). Site 1, having Cyphastrea serailia being infected with highest number of diseases is characterized by the maximum metal concentrations of Zn, Cd, Pb and Ni in water and highest metal concentrations for Cu, Zn and Pb in sediments. Site 2, having M. dichotoma being infected with the highest number of diseases, is characterized by the highest Cu concentration in water. Site 4, having fewer number of coral diseases and highest percentage disease cover attained the highest levels of Cd and Ni in sediments.

Abstract. Pyasi A, Soni KK, Verma RK. 2013. Effect of ectomycorrhizae on growth and establishment of sal (Shorea robusta) seedlings in central India. Nusantara Bioscience 5: 44-49. The aim of the present study was to develop ectomycorrhiza in sal sapling outside the sal growing areas. For this purpose sal seedling were raised at Jabalpur which is around 80 km away from natural sal forest (Motinala, Madhya Pradesh, India). Seed sowing was done with inoculation of ectomycorrhizal inocula prepared by isolating the fungi from surface sterilized young basidiocarp of Lycoperdon compactum and Russula michiganensis. The inocula of ectomycorrhizal fungus were prepared in wheat grains treated with gypsum. The synthesis of ectomycorrhiza was observed in the sapling planted in the experimental field at Jabalpur with production of basidiocarp of Lycoperdon compactum near saplings. The mycorrhized saplings also showed higher growth indices.
