Study on factors affecting facultative parthenocarpy and fruit development in tomato [PDF]
, 1993 兼性单性结实番茄 Severianin, RP75/59, Pset一1, Oregon Spring 和` Santiam 可在不利环 境条件下自然结果, 但用植物生长调节剂点花能显著促进结果, 而非单性结实番茄在相同条件 下自然坐果率极低。人工蕾期辅助授粉能显著提高单性结实番茄的坐果率和单果种子数, 并降 低其单性结实率。去雄处理导致Severianin 和Oregon Spring 的坐果率显著降低, 而去雄同时 授无生活力花粉能使RP75/59 的坐果率显著提高 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Acknowledging the limitations of existing measurement instruments in adequately capturing the distinct cognitive processes (e.g., form‐focused vs. meaning‐focused) involved in informal digital learning of English (IDLE), this paper asserts a pressing need to develop and validate robust instruments that measure form‐focused and meaning‐focused ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Molecular cloning, expression of heat shock protein 60 (HSP60) gene in Marsupenaeus japonicus and the association of its polymorphisms with thermal tolerance [PDF]
, 2015 日本囊对虾(Marsupenaeusjaponicus)是我国重要经济养殖虾类，但其在南方地区存在着高温度夏死亡率较高的养殖难题。因此，急需了解日本囊对虾的耐热性状及耐温的分子机制，为此，我们开展了日本囊对虾MjHSP60基因的克隆、表达分析及其多态性与耐热性状相关性的研究，获得了如下主要结果： 1.MjHSP60基因克隆 在日本囊对虾MjHSP60cDNA序列基础上克隆到了该基因DNA全序列。日本囊对虾MjHSP60基因全长4055bp，结构与拟穴青蟹一致，均由8个外显子及7个内含子构成 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Interlingual translation, as defined by Roman Jakobson, refers to the transfer of meaning between languages. However, this concept has often been conflated with linguistic shifts between distinct cultures and nation‐states. To challenge this misconception, I propose the concept of self‐consumption translation (SCT), a subfield of interlingual ...
