Seasonal dependence of rooting success in cuttings from natural forest trees in Madagascar

Four ligneous species from the tropical forest in the east of Madagascar, with a proven or potentially high economic value, were subject to ‘low-tech’ vegetative propagation tests from stem cuttings. The species concerned were Aphloia theiformis, Ilex mitis, Prunus africana and Ravensara aromatica. The cuttings were three-node segments of stems on which one leaf was retained. All the species proved amenable to rooting. The maximum percentage of rooting ranged from 33% for P. africana to 60% for I. mitis. Rooting success was dependant on the season of cutting (high in the hot season, from October to May, and null in cold season). This study is the first successful attempt at propagating cuttings from Malagasy forest species. This result is of particular importance to P. africana, threatened by destructive exploitation in Madagascar. It goes a step further in the domestication of this species by demonstrating the ability of cutting from 10 year old ortets collected in natural forest to root as it offers the possibility of a reliable and effective method of reintroduction for the species in overexploited zones.     

修辞与语用词义的生成

修辞是语用词义生成的途径之一,两者有共同的思维、心理基础,词义通过修辞手法在语境中获得修辞变体,词义的修辞变体可以在原词义基础上发生临时变化而形成语用词义。修辞联想指以各种修辞手法的运用作为引申理据的语用词义引申方式,包括比喻联想、借代联想、双关联想、反语联想、比拟联系和象征联想等。     

隐喻能力与词汇习得的关联性刍议

隐喻是人类理解与把握世界的认知方式。隐喻能力的熟练掌握是学习者学习词汇的重要标志。隐喻能力与词汇习得彼此之间是相互制约、相互促进的。隐喻能力越强，词汇的习得就越容易；反之，词汇的习得就越困难。     

Sucrose assists selection of high‐quality oocytes in pigs

We investigated whether high‐quality in vitro matured (IVM) oocytes can be distinguished from poor ones based on the morphological changes after treatment with hyperosmotic medium containing 0.2 mol/L sucrose in pigs. We hypothesize that IVM oocytes maintaining round shape have higher quality than mis‐shapened oocytes following dehydration. Oocyte quality was verified by determining embryonic developmental competence using in vitro fertilization, nuclear transfer and parthenogenetic activation. In all cases, the round oocytes had greater (p < .05) developmental competence than that of mis‐shapened oocytes in terms of blastocyst rate and total cell number in blastocysts obtained after 6 days of in vitro culture. We also confirm that round aged oocytes are higher in quality than mis‐shapened aged oocytes. In an attempt to find out why high‐quality oocytes maintain a round shape whereas poorer oocytes become mis‐shapened following sucrose treatment, we examined the arrangement of actin microfilaments and microtubules. Abnormal organization of these cytoskeletal components was higher (p < .05) in mis‐shapened oocytes compared to round oocytes after 52 hr of IVM. In conclusion, sucrose treatment helps selection of high‐quality oocytes, including aged oocytes, in pigs. Abnormal cytoskeleton arrangements partly explain for low developmental competence of mis‐shapened oocytes.

Public and Private Employers’ Perceptions of the Competence of Botswana College of Agriculture Graduates

A large sample size technique was used to select 30 employers each from the private and public sector to examine their perception of the competence of agricultural graduates. Data were collected with a structured questionnaire and analyzed using means, standard deviation, and t test. The results show that, for 16 crop production tasks, public agroemployers were favorably disposed to competence in 4 tasks, while private employers were not favorably disposed to competence in any tasks. Both public and private employers were not favorably disposed to competence in farm engineering tasks. The Botswana College of Agriculture curriculum should be overhauled to better prepare graduates for employment.
