选用２５个新品系，估算了熟期、株高等９个性状的遗传力、遗传度等６个遗传参数，并以这些参数为选择性状的指标构建了６组选择指数。试验结果表明：所有选择指数都比直接选择产量的效率高。以遗传进度（ｒｇ）为基础的选择指数效率最高，遗传进度（Ｇａ）次之，接下来是遗传力×遗传相关（ｈ２×ｒｇ），通径系数（ｐ）和遗传变异系数（ＧＣＶ％），以遗传力（ｈ２）为基础的选择指数效率最低。选择指数的相对效率随着性状数目的增加而增高，但增加每荚粒数和百粒重两个性状并不提高相对效率，可能是这两个性状与产量的遗传相关较低的缘故。遗传相关是构建选择指数时选择性状的最佳指数。

[Objectives]This study was conducted to provide technical standards for domestic Spathiphyllum variety description and resource evaluation.[Methods]Through field trials and character surveys of the collected 83 Spathiphyllum varieties,after several revisions by fellow experts,and with reference to the Guidelines for Testing the Specificity,Consistency and Stability of New Plant Varieties:Spathiphyllum(TG/135/3)issued by the International Union For The Protection of New Varieties of Plants,the DUS testing guidelines for Spathiphyllum have been developed,and statistical analysis and other methods were used to study the traits for the guideline.[Results]Thirty two testing traits,including 11 mandatory traits,8 basic traits,10 new traits,and 3 optional traits were finally determined;five traits including plant height,plant width,and leaf length were divided into 7 grades,and 9 traits such as leaf width,spathe length,and spathe width were divided into 5 levels;and the observation method and trait code of the trait spathe depth were adjusted.[Conclusions]The development of this guideline provides a basis for judging the specificity,consistency and stability of Spathiphyllum varieties,and is of great significance to the breeding and protection of Spathiphyllum varieties.

The spatial consciousness of the ancients is reflected in the character formation,structure,and writing of the oracle ***‟s genetic epistemology,Merleau-Ponty‟s philosophy of body,and cognitive linguistics suggest that human spatial awareness is derived from the formation of a spatial awareness of the body,and evidence for this can be found in the body-related characters in the oracle *** a combination of symbols and images,the oracle bones are themselves a spatial metaphor that can compensate for the lack of symbolic language and serve as a reference for the aesthetic language advocated by Adorno.

The main objective of this work is to study the effect of sulphur application and irrigation water quantity on some soil properties of the calcareous soils and to limit the suitable concentration to obtain satisfactory yield of faba beab under saline conditions. The study area (Tamyia district, Fayoum Governorate, Egypt) is characterized by a hot and dry climate in general with annual rainfall average of 8 mm/year, whereas the evaporation rates average ranging between 3.5 to10 mm/day. Faba bean (Vicia faba L.) was sown at 18 November 2010 and harvested at 26 April 2011. Total water consumed during faba bean growing season were 623.7 and747.2 m3/ fed for 100% and 120% irrigation treatments with increasing ranged between 3.5% and 3.7% in same sequence. Results showed that values of soil EC, pH and CaCO3 was improved as a result of both irrigation and S treatments. The improvement resulted in a gradual reduction of the studied soil properties by about 10.3%, 3.2%;17.0% and 23.1%, 4.3%;11.3% comparing S treated plot relative to the control plot at 100 and 120% irrigation treatments. Application S improved water content under studied soil constant and these increases were 8.8%, 11.8%, 8.3% and 16.9% for SP, FC, WP and AW, respectively relative to the control plots. Irrigation 100% had a positive effect on the drainable pores% which increased by about 7.0% comparing with 120% irrigation treatments. While hydraulic conductivity increased by about 16.4% and percentage of increase drainable pores was 14.0% and 21.4% for 100% and 120% irrigation treatments comparing 3rd layer with the 1st one, respectively. Increasing irrigation water from 100% to 120% resulted increasing in the studied macronutrients, N, P and K, by about 80.8%, 144.9% and 72.9%, respectively;while they increased in plant by about 118.8%, 132.8% and 62.2% as compared with the control one, respectively as a result of S application. Results showed that Na, Cl and Na/K ratio that increasing irrigation water cau
