A study was performed to develop hydrological river basin coding for Turkish river basins using the pfafstetter coding system. The coding system developed in this study is based on the combination of ECRiNS and pfafstetter methods. River Basin District concepts were incorporated in this method so that it can be applicable to the management of Turkish River Basins. Developed hydrological river basin coding system is flexible, versatile and fits to all types of basins in Turkey. in order to show the efficiency of the coding system, it was applied to three river basins each of which has different hydrological and topographical features from the others. The basins used for the application of the coding system have complex features such as being transboundary basins, or being coastal basins whose discharge is not joining to the main drainage system, or being a closed basin discharging to an inland lake. Using the developed hydrological river basin coding defines river basin boundaries accurately, preventing conflicts in sectorial water allocation that are caused by uncertainty in the locations of water sources, producing a base for determining water potential and estimating extreme hydrological events of the basin, producing a basis for the prevention of water disputes among stakeholders within the basin, and helping implementation of integrated Water Resources Management (iWRM) at basin level.

AiM: To investigate the effects of selenium in rat retinal ischemia reperfusion(iR) model and compare pretreatment and post-treatment ***: Selenium pre-treatment group(n =8) was treated with intraperitoneal(i.p.) selenium 0.5 mg/kg for7 d and terminated 24 h after the iR injury. Selenium posttreatment group( n = 8) was treated with i. p. selenium0.5 mg/kg for 7d after the iR injury with termination at the end of the 7d period. Sham group(n =8) received *** injections identical to the selenium volume for 7d with termination 24 h after the iR injury. Control group(n =8) received no intervention. Main outcome measures were retina superoxide dismutase(SOD), glutathione(GSH),total antioxidant status(TAS), malondialdehyde(MDA),DNA fragmentation levels, and immunohistological apoptosis ***: Compared to the Sham group, selenium pre-treatment had a statistical difference in all parameters except SOD. Post-treatment selenium also resulted in statistical differences in all parameters except the MDA levels. When comparing selenium groups, the pre-treatment selenium group had a statistically higher success in reduction of markers of cell damage such as MDA and DNA fragmentation. in contrast, the post-selenium treatment group had resulted in statisticallyhigher levels of GSH. Histologically both selenium groups succeeded to limit retinal thickening and apoptosis. Pre-treatment use was statistically more successful in decreasing apoptosis in ganglion cell layer compared to post-treatment ***: Selenium was successful in retinal protection in iR injuries. Pre-treatment efficacy was superior in terms of prevention of tissue damage and apoptosis.

以江西省南城县麻姑山地区的51份野生毛花猕猴桃(Actinidia eriantha Benth)雄株种质资源为材料,对野生毛花猕猴桃雄花花器官形态变异、花粉贮藏特性、热胁迫耐受性和冷藏后花粉授粉后果实品质进行了研究,主要结果如下:1、野生毛花猕猴桃雄株种质花器形态学性状的聚类分析供试的野生毛花猕猴桃雄株花粉活力的变异系数最大,为59.21%,花瓣基部萼裂处花青素着色程度、花柄长度、花瓣数目及花瓣颜色等指标的变异系数达20%以上。利用DPS 9.50分析软件,以平均Euclidean距离4.10为界,可将51份野生毛花猕猴桃雄株种质资源分为3大类及2个独立单株。第Ⅰ类为高花粉活力型,第Ⅱ类为小花型,第Ⅲ类为深色花型。野生毛花猕猴桃雄株花器形态变异大,遗传多样性丰富,可为毛花猕猴桃特异种质筛选及雄性品种选育奠定理论基础。2、热胁迫对毛花猕猴桃贮藏花粉活力的影响经热胁迫处理(27°C、30°C、33°C和36°C)后,各单株间花粉活力差异显著,热处理间差异显著,其中八个单株花粉活力没有显著变化。单株花粉的花粉管长度与温度变化间无相关性。MH22、MH30和MH58为耐热性花粉,相比之下,MH48和MH67为是热敏性花粉。3、贮藏时间对花粉活力的影响-20℃下贮藏不同时间处理后,不同单株花粉活力之间差异显著。MH22、MH45、MH47、MH56、MH67、MH70、MH71、MH72、MH74、MH55和MH61为花粉活力较高的单株,在长时间的贮藏下保持了活力和萌发的能力,除MH67外,其它单株花粉活力与花粉管长度随贮藏时间的增加而降低。4、野生毛花猕猴桃花粉贮藏后人工授粉对果实质量的影响贮藏花粉的体外萌发和受精能力不同,受精后果实品质性状包括干物质、总糖、酸、维生素C、总多酚、总黄酮、叶绿素、类胡萝卜素含量和可溶性固形物有显著差异。MH67和MH45基因型被鉴定为最适合贮藏后授粉的雄株。

We examined the influence of storage time on germinability and tube growth of freeze stored pollens collected from 25 wild male plants in Actinidia eriantha variety. Pollens were stored in freezer at - 20°C for six months and one year periods to determine changing at germinability in time. in vitro germination was conducted in certain cultural medium defined for Actinidia genus. The results showed that the germination percentages and tube lengths of genotypes decreased at the end of storage period. MH22, MH45, MH47, MH56, MH67, MH70, MH71, MH72, MH74, MH55 and MH61 genotypes were evaluated as vigor genotypes, because they maintained their viability and germination capability displaying statistically insignificant decreasing although their tube lengths significantly decreased except MH67. This investigation provided to determine some robust wild male germplasm resources in A. eriantha in point of durability of pollens against long term conservation for using at future pollination and breeding programs.

Our study was conducted to determine in vitro germination ability of pollens from 25 wild Actinidia eriantha genotypes after one year freeze storage, afterwards we examined fertilization ability of stored pollens of 8 genotypes selected according to in vitro test results from aforementioned 25 genotypes, and finally investigated effects of stored viable pollens from “MH67”, “MH55”, “MH48” and “MH45” genotypes on fruit quality characters of the female experimental plant “M3” as the main purpose. Non-pollinated “M3” kiwifruit plant was taken as control. We found that in vitro germination and fertilization ability of different stored pollen sources, and also fruit quality characters including dry matter, total sugar, titratable acid, vitamin C, total polyphenol, total flavonoid, chlorophyll (“a”, “b”, and total) and carotenoid contents except total soluble solid content were significantly different. MH67 and MH45 genotypes were evaluated as the most suitable pollenizers which can be recommended as new candidate cultivars because of long term storage ability and brought about desired fruit quality characters. They also will be investigated more at further breeding studies.
