Design of sampling plan using auxiliary information
Aslam, Muhammad,Satti, Saqlain Latif,Moemen, Mitwali Abd-el,Jun, Chi-Hyuck Informa UK (TaylorFrancis) 2017 Communications in statistics. theory and methods Vol.46 No.8
<P>In this manuscript, a variable sampling decision rule for product acceptance is proposed when the additional or auxiliary information is available for the quality characteristics under study. The auxiliary information is usually correlated with the quality characteristics and so the regression estimator is used to develop the proposed sampling plan. To find the plan parameters, the two-point approach is adopted such that producer's risk and consumer's risk are satisfied. The advantage of the proposed plan is discussed with the usual single plan without auxiliary information. Tables are given for practical uses and explained with the help of industrial examples.</P>

Faba bean (Vicia faba L.) is one of the most important legume crops worldwide. High salinity is a major constraint for faba bean productivity in many countries, including Egypt. Here, we examined the efects of salinity-induced toxicity on the growth of two local faba bean genotypes by analyzing physiological and biochemical responses to identify the salt-tolerant attributes between the genotypes. In vitro experiments were carried out to characterize the response of two faba bean genotypes (Sakha 3 and Nubaria 2) to salinity imposed by diferent sea-salt concentrations (1000, 3000, 5000 and 7000 ppm). For both genotypes, salinity induced a marked reduction in dry matter gain along with a reduction in shoots height, roots length, leaves number and branches number. In addition, the photosynthetic pigments (chlorophyll a, b) were signifcantly decreased with the increase in salinity. Changes in tissue ion levels, peroxidase (POD) and polyphenol oxidase (PPO) activities depended on genotype, tissue and salinity level. The deteriorating efect of salt stress on the growth performance of genotype Nubaria 2 was lower than that of Sakha 3. This is maybe ascribed to its better antioxidant enzymes activities. Moreover, Nubaria 2 accumulated low quantities of Na+ in the shoots with a higher accumulation of ions in the roots compared to Sakha 3. The obtained results suggested Nubaria 2 seedlings have a strong ability to sustain sea-salt stress by the regulation of transport and distribution of ions and this genotype may be characterized as a salt excluder.
