一、插条: 番木瓜除通常采用播种繁殖外,截取小枝条使其在愈合处自然生长也是可行的。番木瓜插条在温室沙床内能很好地生根。 Allan在试验中采用间歇喷雾与内部加热的方法,其生根率可达80～90％,五周后,生根的插条可进行移植。插条的切端因木瓜乳的分泌,一般会形成一薄层,而导致组织坏死。为避免此情况发生,先连根挖起生长达10～12个月的番木瓜植株,将其保持在潮湿的环境里十天,使其乳汁浓度变稀成水状,再截取10～15厘米长的枝条,用1,000 ppm的吲哚丁酸处理,其生根率可达42.5％,而对照仅为20％(Bhuva)。

喷雾处理促进热带果树扦插发根

亚热带植物科学 1989年第1期28卷 62-63页

作者： R.s.Dhua s.k.mitra 庄馥萃

果树通常用种子繁殖。因为大多数果树在自然界中是异花授粉的,所以不能由种子培育出纯种植株。但是,可以用压条、嫁接法繁殖这些果树。虽然扦插是花钱最少的一种营养繁殖方法,但是获得成功还是有限的。因为有些果树扦插容易生根,有些... 详细信息

果树通常用种子繁殖。因为大多数果树在自然界中是异花授粉的,所以不能由种子培育出纯种植株。但是,可以用压条、嫁接法繁殖这些果树。虽然扦插是花钱最少的一种营养繁殖方法,但是获得成功还是有限的。因为有些果树扦插容易生根,有些扦插尚可生根,而相当多种则完全不能生根。插条生根潜力的这些差异,在很大程度上可能是由于激素和非激素生根因子及辅助因子不同所致。

Model selection strategies have been routinely employed to determine a model for data analysis in statistics, and further study and inference then often proceed as though the selected model were the true model that were known a priori. Model averaging approaches, on the other hand, try to combine estimators for a set of candidate models. specifically, instead of deciding which model is the 'right' one, a model averaging approach suggests to fit a set of candidate models and average over the estimators using data adaptive *** this paper we establish a general frequentist model averaging framework that does not set any restrictions on the set of candidate models. It broaden, the scope of the existing methodologies under the frequentist model averaging development. Assuming the data is from an unknown model, we derive the model averaging estimator and study its limiting distributions and related predictions while taking possible modeling biases into *** propose a set of optimal weights to combine the individual estimators so that the expected mean squared error of the average estimator is minimized. simulation studies are conducted to compare the performance of the estimator with that of the existing methods. The results show the benefits of the proposed approach over traditional model selection approaches as well as existing model averaging methods.
