  • In vitro regeneration techniques in the grass pea (Lathyrus sativus L.)

    • Authors: Muhammed İkbal ÇATAL; Adil BAKOĞLU
      Abstract: The Lathyrus genus is in thelegumes family with annual or perennial species number of 160. There are 58species naturally grown in our country, 18 of them are endemic. In our region, 8 species were identified, 2 of them were endemic. In the world, Lathyrus species are evaluated in the animal feed as green grass,hay and grain feed, fertilization of soil as a green manure plant and humannutrition as food grain legume plant. The cultivation of Lathyrus species are very rare in our country and are generallyused in animal feeding and in small quantities in human nutrition. Grass pea (Lathyrus sativus L.) plant is the mostused species in the world and in our country because it is resistant to adversesoil conditions, drought and flooding. Various tissue culture methods are usedto develop and reproduce this species. Plant tissue culture is being appliedboth in the development of new varieties and genetic changes in existingvarieties, and in the production of species which are difficult to reproduceand protect of the disappearing species. The basic system used in plant tissueculture processes and genetic improvements is plant regeneration. In thisreview, some studies related to the in vitro regeneration techniques of thegrass pea plants have been put together and the techniques used in regenerationhave been evaluated.

  • Sustainability of wood harvesting in tropical rainforest of Nigeria

    • Authors: Kufre OKON
      Abstract: Over the years, Nigerian tropicalrainforest has become the main source of timber supply to many countries whichwere in critical need of timber to feed their wood-based industries. Theincrease in population has led to increase in the demands for forest products,specifically wood for construction. Improper harvesting practices hassubstantially degraded the tropical forest that future timber values may bereduced. Sustainable wood harvesting focuses on the trees that are remainingrather than on the trees that are to be fell. Proper wood harvesting andmanagement method must be adopted to facilitate the regeneration of the forest.Efficient wood harvesting in Nigeria requires the construction of landing sitesas collection points for the harvested timbers and adequate training must beprovided to the operators of the diverse harvesting equipment. With propertimber harvesting techniques, the damages caused by logging can be minimized. Functional forestpolicies that guide against over-exploitation of timber should be enacted.Reduced impact logging should be incorporated into sustainable forestmanagement to reduce devastating damages to the residual trees in the forest.

  • A study on antioxidant properties of Gyrodon lividus

    • Authors: Celal BAL
      Abstract: It is possible to classify mushrooms as edible, inedible and poisonous. Thepresent study aimed to determine the antioxidant potential of Gyrodon lividus (Bull.) Sacc., an ediblemushroom species Thus, total antioxidant status (TAS) and total oxidant status(TOS) of mushroom ethanol extracts were determined and oxidative stress index wascalculated based on TAS and TOS findings. Based on the study findings, the TAS valuewas 2.077 ± 0.087, TOS value was 13.465 ± 0.213 and OSI level was 0.651 ±0.037. Thus, it was suggested that the mushroom had antioxidant potential, howeverG. lividus collected in Burdur provinceshould be consumed with care due to the high oxidative stress levels.

  • Archaeobotanical Studies at Sumaki Höyük (Batman, Turkey) in

    • Authors: Leman Kutlu; Aslı Erim Özdoğan, Ernaz Altundağ Çakır
      Abstract: Our study focuses on the archaeobotanical analyses of 2014 seasonof the Sumaki Höyük, which is located east of Beşiri town in Batmanprovince. It was excavated within theframework of Ilısu Dam and HES project by the Batman Museum at the charge ofDr. Aslı Erim Özdoğan.Sumaki Höyük yields Late Pre-Pottery NeolithicB (LPPNB) and Early Pottery Neolithic, namely Pre-Proto Hassuna and ProtoHassuna phases, dated to 7310 - 7040 cal BC - 6480 - 6400 cal BC. The uppermostphase is a small farm or a district belongs to Abbasid / Hamdani Periods datedto cal. 770-890 AD. Most of the 2014 botanical samples are collected from thephases dated between cal. 7030-6580 BC and cal. 6830-6470 BC. The archaeobotanical remains were obtained by flotation of 348 lt soil of 45 samples that werecollected from different loci at Sumaki Höyük. The remains are preserved eitherby carbonizing or mineralizing. Two domesticated families Poaceae and Fabaceae are predominant. The earliestdomesticated form of wheat Triticum dicoccon (Schrank) Schübl. Grains, as wellas pieces of spikelet forks, aredetermined. Among the Fabaceae familyLens culinaris Medik. (lentil), Vicia ervilia(L.) Willld. (bitter vetch), Pisum sativum L. (garden pea) and Cicer arietinum L. (chickpea) speciesare vegetal source of nutrition of semi-nomadic inhabitants of SumakiHöyük. The existence of Linum L.(Linen) might be the indicator of weaving and/or oilconsumption.

  • Effect of accelerated aging test on fungi formation in stored eggplant

    • Authors: Burcu Begüm KENANOĞLU; Havva DİNLER
      Abstract: Seeds of fleshy fruits group need specific processes such as fermentation (Silva et al. 2009). Acid applications, which is one of the fermantation methods are widely used in the fleshy fruits group, are given fast and practical results. Accelerated aging test is determined seed can be stored at high humidity and temperature and If don‟t taken some measures, fungal contamination can be increase. In this study, Kemer egglant seeds, which were harvested two different seed maturity period (50 and 65 days) and were subjected three different fermentation treatments (water, 10 min. HCl, 20 min. HCl) and stored at 4 °C for 8 years, seed vigor and fungal contamination rates were decreased with accelerated aging test. Accelerated aging test (AAT) was carried out; surface sterilization (2% of NaCl 2 min.) treated (SS) and untreated (NSS) with 41 °C at 72 h period in the seed of the two groups.In the next stage, percentage of fungal contamination was calculatedat the first week of germinated seed lots. According to the results; the fastest (mean germination time, 5 days) and the highest germination rate (average germination rate, 73%) obtained from the seed lots which weren’t done AAT and harvested 50 days and were treated with HCl fermentation at 20 minutes. 65 days harvested seed lot’s mean germination time and rate were calculated as 67% and 5 days, respectively. According AAT results; 50 harvested seeds that were given high value, viability decreased by 20% and fungal contamination was 2%, in the NSS group seed viability decreased 3% and infection was found in 25%. Generally, surface sterilization treatment prevented contamination of 67% of total treatments. Pathogens which found at the surface of seed are Penicillium spp., Aspergillus spp. ve Alternaria spp. eliminated.

    • Authors: Ranjeet Kumar Singh; Manmohan Singha, Shailendra K. Singh, Debjeet Pal, Nimisha Tripathi, Raj Shekar Singh
      Abstract: Mining and human activitiesimpacted the natural ecosystem leading to land use/land cover (LU/LC) change isof great concern by environmentalist and the society. The present studyevaluated the LU/LC changes due to exploitation of coal in Dhanbad district ofIndia during the period of 1987 to 2017. Remote sensing (RS) data indicated thatout of 2043.32 ha LU/LC comprised of dense forest, low dense forest, openscrub, agriculture land, agriculture fallow, barren land, sand, river, waterbody, built-up and mining, constituted percent values of 8.17, 3.11, 39.51,18.88, 12.69, 1.25, 0.76, 3.12, 2.88, 4.40 and 5.22 in 1987 and 4.69, 6.01,15.78, 41.36, 9.97, 3.90, 2.55, 2.22, 1.43, 7.91, 4.18 in 2017 respectively.The LU/LC during 30 years indicated the percent share of dense forest, openscrub, agricultural fallow, river, water body and mining decreased by 42.63,60.45, 21.47, 28.80, 50.37 and 19.85 % respectively.Land use changes were due to harvesting of forest for fuel, shelter andagriculture, construction of residential houses in fallow land, urbanizationand sand removal for construction material. The increase in low dense forest,agricultural land, barren land, sand and built-up area by 93.38, 119.06,211.63, 234.96 and 79.85 percent respectively were due to shift of land usefrom forest to open scrub, agricultural fields and barren lands, new settlementby utilizing sands from river banks making the river stretch wider, open minepits converted into water bodies in the district. These resulted in aconsiderable change in land use pattern in Dhanbad district, Jharkhand, India.
