After reviewing the previous dissertation on quantitative characteristic trait of recalcitrant seeds, three aspects of quantitative characteristic trait of seed recalcitrant were defined, which are interspecific aspect, intraspecific aspect and individual developmental aspect. And it was supposed that seed recalcitrance was a compound characteristic, with its core composed of desiccation tolerance, low-temperature tolerance and storage tolerance at least, and its concomitants composed of seed size, 1000-seed weight, moisture content at shedding, non-dormancy, systemic taxonomy, ecological and biochemical aspects. Because these core and concomitants are all gradual, transitional and quantitative, it was inferred that seed recalcitrance was a compound quantitative trait.

文章简要概述了从顽拗型种子到顽拗性种子这样一个对顽拗性种子认识提高的过程,在综述了前人关于顽拗性种子数量性状特征论述的基础上,把种子顽拗性的数量性状特征划分为种间、种内和个体发育三个层面,提出种子顽拗性是一种复合性状,其核心至少包括脱水耐性、低温耐性和贮藏耐性三方面的内容,其伴随性状包括种子尺度、千粒重、初始含水量、休眠特性、分类地位、地理分布和保护性物质含量等多方面的内容,而且这些核心内容和伴随性状的每一个方面都具有渐变的、过渡的、数量型的特征,从而阐明种子顽拗性是一种复合数量性状。

Using different concentrations of PEG solution simulated drought stress, measured PB86, PR107, RRIM600 and GT1 rubber tree seedling leaves relative water content, the relative conductivity, malondialdehyde, soluble sugar content, superoxide dismutase, 8 physiological indicators, and their changes in the law, and using principal component analysis, membership function analysis, correlation analysis grey mathematical statistical methods, such as the evaluation of four strains of rubber tree seedlings and with the drought resistance the relevance of indicators; at the same time analysing the use of hypertonic solution screening rubber tree seeds and the drought resistance of different rootstocks on 7-33-97 budding seedlings of the impact of drought that rubber tree planting material and rootstocks drought assessment, and provide a theoretical basis choice.

利用不同浓度的PEG溶液模拟干旱胁迫,测定了PB86、PR107、RRIM600和GT1橡胶树实生苗叶片相对含水量、相对电导率、丙二醛、可溶性糖含量、超氧化物歧化酶等8项生理指标,研究了它们的变化规律,并利用主成分分析、隶属函数分析、灰色关联分析等数理统计方法评价了4个品系橡胶树实生苗的抗旱性及其与各指标的相关性;同时分析了利用高渗溶液筛选的橡胶树种子的抗旱性以及不同砧木对热研7-33-97芽接苗抗旱性的影响,以为橡胶树抗旱砧木和种植材料的评价、选择提供理论依据。

When the Agropyron seeds were treated with 1.0kv.cm-1,the seedling rate,seedling length and root length increase by 4.5%,81% and 48% respectively,and treated with 4.5kv.cm-1,the seedling rate,seedling length and root length increase by 4.8%,84% and 66% respectively.

结果表明:不同电场对冰草种子萌发及幼苗生长产生不同的影响,用1.0 kv/cm电场强度处理冰草种子10 min,可提高种子出苗率4.5%,苗长增长81%,根长增长48%;用4.5 kv/cm电场强度处理冰草种子10 min,可提高种子出苗率4.8%,苗长增长84%,根长增长66%。

Farm. In the past (until app. 25 years ago) pistachiodiversity was maintained high in the field through a number of cultivation practices, s.a. use of male varieties derived from seed, use of wild Pistacia species to boost pollination and hence the fruit setting, use of natural populations of wild Pistacia (P. atlantica) as rootstock due to their well known resistance to stony and calcareous soils.

最近在农场栽培无花果技术的改变更加导致作物的多样性减少。25年前,无花果多样性通过多种栽培保持在很高的水平(源于种子的雄性物种采用,野生开心果物种改善授粉的采用,自然野生开心果作为根茎的采用——因为他们已知很好的抵抗多石和石灰性土壤的能力,等等

In Ceylon the Sylvestrine Benedictines have undertaken (1883) missionary work amongst the natives in the Diocese of Kandy, the bishop of which is a member of the order; and still more recently the congregation of St. Ottilien, expressly established to provide workers for the foreign mission field, has established missions amongst the native tribes of Central Africa, where the seeds of the Faith have already been watered by the blood of its first martyrs.

The results showed that O. fragrans seeds were desiccation-sensitive as the seed viability declined to 6% when the seed moisture content was reduced to 11.6%. The seed electrical conductivity increased with the declining moisture content, a sign, which was caused by increasing cell membrane cleavage. Superoxide dismutase activity decreased rapidly during desiccation; but peroxidase activity increased to the maximal value when dehydration for 12 h, then declined rapidly when seeds were dehydrated more than 12 h.

There remained the generic conditions imposed by natural, as distinct from human law, as integral parts of the human whole: the necessity of destruction to procure alimentary sustenance: the painful character of the ultimate functions of separate existence, the agonies of birth and death: the monotonous menstruation of simian and human females extending from the age of puberty to the menopause: inevitable accidents at sea, in mines and factories: certain very painful maladies and their resultant surgical operations, innate lunacy and congenital criminality, decimating epidemics: catastrophic cataclysms which make terror the basis of human mentality: seismic upheavals the epicentres of which are located in densely populated regions: the fact of vital growth, through convulsions of metamorphosis, from infancy through maturity to decay.

Personally, even with the May 27th pole shift date come and gone, we are continuing preparations - we have added to our freeze dried food and seed stores and we now have multiple systems to collect water, store water, purify water and heat water and are currently working on the bicycle powered air infiltration system to our shelter as well as have added two 4 x 10 solar panels to the shelter roof to produce water, have purchased two 120 photovotaic panels to make electricity with along with a charge controller and deep cycle RV batteries, and now have a bicycle generator ( a really nice unit found at www.windstreampower.com ) to produce electricity should there be no sun along with two 12VDC to 120V invertors for running small appliances and even the washing machine.

就个人而言,即使2003年5月27日---极移的日期来了又溜走,我们还是在继续做准备----我们已经增加了冷冻干食品和种子的储存量,并且有了收集,存储,净化和加热水的复合系统设备。我们现在正致力于为避难所建造由自行车供电的空气渗透系统,还在避难所的屋顶上加入了2个4x10的太阳控电板,以便制造出水源。我们也购买了两个120光生电池板和两个充电控制器,以及可多次循环使用的 RV 电池,用于供电。现在我们已有了自行车发电机(在 www.windstreampower.com 上发现的一个很不错的东西),没有阳光的时候用于发电。
