^(60)Co-γ辐照处理对绿莴笋种子的影响

[目的]选育品质优良的绿莴笋品种。[方法]用剂量分别为0(对照)、20、40、60、80、100、150、200 Gy的60Coγ-射线辐射处理泰国绿莴笋种子,研究60Coγ-辐射处理对绿莴笋种子萌发及幼苗生长的影响。[结果]60Coγ-辐射剂量为20、150、200 Gy时,绿莴笋种子发芽率高于对照。绿莴笋种子发芽率与60Coγ-辐射剂量呈正相关,辐射剂量为20 Gy时发芽率最高。60Coγ-辐射剂量为60 Gy时绿莴笋幼苗长势较对照好。辐射剂量在20~60 Gy范围内时,剂量越大,幼苗长势越好。绿莴笋幼苗根长在辐射前期与60Coγ-辐射剂量呈正相关,芽长与60Coγ-辐射剂量呈正相关。[结论]60Coγ-辐射剂量为20 Gy时绿莴笋种子发芽率最高,辐射剂量为60 Gy时绿莴笋幼苗长势最好。

The Concept of the Higher/the Lower Energy in the Atmopadesa Satakam of Narayana Guru

The paper presents an analysis of the concept of the higher/the lower energy （para-apara maya/prakrti/sakti） in the Atmopadesa Satakam （＂One Hundred Verses of Self-instruction＂）, the most important philosophical work of Narayana Guru composed in Malayalam. In order to better understand the issue, the same pair of opposites is discussed at length on the basis of Narayana＇s earlier Malayalam poems--devotional hymns （Siva Satakarn--＂One Hundred Verses on Siva＂, Kah Natakam--＂Dance of Kali＂, and Janani Nava Ratna Manjari--＂Nine Gemmed Bouquet to Mother＂） as well as later Sanskrit philosophical work [Darsuna Mala--＂Garland of Visions＂）. The comparative analysis of these texts demonstrates that--whereas Darsana Mala reflects more or less accurately Vedantic concepts, Atrnopadesa Satakam presents deeply syncretic formation, influenced to a large extent by philosophical systems related to bhakti （devotion）, like Sata or Saiva Siddhanta. The reason for such a state of affairs could be the purpose of Malayalam work destined to become vehicle for instructions given to lower caste people in Kerala. The paper offers an analysis of the relevant passages of the texts accompanied with explanatory notes extracted from the commentarial literature.
