In Vitro and In Vivo Characterization of Alpha-1A Selective Agonists and Their Utility for Stress Incontience
      
A new way to estimate the parameters in the progressive stress accelerated life testing
      
In this article a deficiency in the classical approach is pointed out and a new method for the statistical analysis of life data, especially for electronic products, under progressive stress (voltage)V(t) =Kt is given.
      
Using the Bayesian method, for certain choices of the prior distribution, several forms of estimators of the parameters in the normal stress Weibull distribution and the inverse power law model are derived.
      
In particular, when the new shape parameter of the distribution under progressive stress is given (or estimated in advance), the closed forms of these estimators are relatively simple and are numerically accessible on computers.

In the light of the existent problems of clone arrangement in Hainan rubber areas. this paper puts special stress on analysing the performance of PR107 in Worst Hainan Island, involving its growth, yield and resistance, so as to have it popularized on a sound basis. The experimental results show that PR107 is really well adapted to West Hainan, For the first five years of tapping, the average per mu (1 mu=1/15 ha) yield of PR107 is slightly lower than that of RRIM600; but for the second five years of tapping,...

In the light of the existent problems of clone arrangement in Hainan rubber areas. this paper puts special stress on analysing the performance of PR107 in Worst Hainan Island, involving its growth, yield and resistance, so as to have it popularized on a sound basis. The experimental results show that PR107 is really well adapted to West Hainan, For the first five years of tapping, the average per mu (1 mu=1/15 ha) yield of PR107 is slightly lower than that of RRIM600; but for the second five years of tapping, that of PR107 is remarkably higher than that of RRIM600 or HK (Haiken) 1 because PR107 has such advantages as higher survival rate in the field, lower incidence of dry trees and rapider increase in yearly average yield after opening for tapping. As for resistance to wind, PR107 is stronger than RRIM600 and comparable to HK 1. In respect of tolerance to cold, either crown or stem of PR107 is superior to that of RRIM600, although the stem of the former is similar to that of HK 1. Moreover, being less susceptible to brown bast disease, PR107 is more tolerant to intensive tapping and gives latex with a particularly high d.r.c.Hence, PR107 is adaptable to stimulated tapping and has a greater yield potential, It is estimated that further use of PR107 may increase the rubber production by 5—20% in West Hainan Island,

针对海南橡胶垦区存在的品种配置问题,本文着重分析PR107在海南岛西部地区的生长、产量以及抗性等方面的反应,以便合理推广使用。研究结果表明:PR107在海南岛西部地区确有良好的适应性,开割头五年的平均亩产置虽略低于RRIM600,但由于大田保苗率高,死皮树少,开割后的产量递增快,第6—10割年平均亩产量显著优于RRIM800和海垦1。PR107抗风能力比RRIM600强,而与海垦1相当(指风力小于12级时),树冠及茎干的耐寒力均比RRIM600强,茎干的耐寒力与海垦1相当。不容易死皮,比较耐割,干胶含量特高,适合于刺激采胶,产胶潜力大。因此,认为PR107可在该地区继续推广使用,并能收较好的增产效果(约增产5~20%)。

The physiological and biochemical indices introduced in this paper are bound water/free water ratio, catalase activity,hydrolytic sugar content, reducing sugar content,cell membrane permeability and cell viability.They vary with the low temperature stress. The same is true of citrus hardi ness.

本文主要阐明在低温影响下,抗寒性强弱不同的柑桔树在束缚水/自由水比例、过氧化氢酶活力、糖分含量、细胞膜透性和细胞生存力等生理生化指标的不同变化和差异,并对这些差异产生的原因和这些指标的测定方法的实际应用进行了初步探讨。其中电导法是一项既简便又快速鉴定柑桔抗寒性的方法。

In regions of the major litchi production area, problems usually arised when flowers of litchi fruit trees at bearing ages(about 15-20 years old) failed to fruit. and conditions such as abscissions of flowers and fruits with unstable or low yields occurred. It was speculated that boron stress may be the cause of failures in pollination or fertilization leading to the decrease of unit area fruit production. Borax in different concentrations together with potassium dihydrogen phosphate gave good results...

In regions of the major litchi production area, problems usually arised when flowers of litchi fruit trees at bearing ages(about 15-20 years old) failed to fruit. and conditions such as abscissions of flowers and fruits with unstable or low yields occurred. It was speculated that boron stress may be the cause of failures in pollination or fertilization leading to the decrease of unit area fruit production. Borax in different concentrations together with potassium dihydrogen phosphate gave good results in promoting leaf contents of boron, nitrogen, and chlorophylls so as to increase fruit yields of healthy bearing litchi trees. Three treatments were eminent in the experiments, namely, B 0.2%~0.4% spray. B 0.2%+KH_2PO_40.2% spray, and B 4-5 liang/tree soil dressing. At the concentration range of 60 ppm. this microelement advanced the germination as well as the growth of pollen tubes. Thus created very favorable conditions for fertilization and greatly increased the fruit setting rates. However, concentrations of borax adove·80 ppm showed inhibitive effects.

适龄荔枝(15~20年生)“花而不实”,落花落果及产量低而不稳,是福建荔枝主产区生产中存在的重要问题。缺硼会影响荔枝授粉受精及单位面积产量。不同浓度硼砂(B)处理的结果表明:喷洒B0.2%~0.4%、B0.2%+KH_2PO_40.2%和土施B4~5两/株,能提高荔枝叶片中硼、氮、叶绿素含量,显著提高荔枝(强壮树)单株产量。硼在60ppm范围内能促进荔枝花粉萌发和花粉管生长,利于受精及提高座果率,超过80ppm浓度却起抑制作用。
