The pod numbers per plant of 4 varieties increased with the application of nitrogen and every yield characteristic index increased sharply especially from lower to middle nitrogen level, but seed weight per pod began to decrease on high nitrogen level.
The rehabilitated forest of age 10 in different models in degraded red soil region located in Taihe County and Yiyang County of Jiangxi Province was taken as the object of the study. The state of undergrowth, some character indexes of soil physical and chamical characters and soil microbe were investigated.
The author measured photosynthetic character indexes of different wheat varieties under the general water-saving condition, analyzed the limited factor of wheat varieties for obtaining higher yield, and discussed the relation between photosynthetic character indexes and the limited factor of higher yield, complied with these, assayed especially the character of the high-yield variety by clustering analysis.
Character index of three kinds of maize in summer seeding area of Guanzhong of Shaanxi province was that LAI was about adapted for 5.5,GAR was ensured to high 14.0 g/m2·d,intercepting and capturing luminous energy of total plant was above 92%,that of leaf of low spike was not under 14%.
Quantitatve relations among the qualitative character index such as the leaf axits and diameters of Citrus unshiu Marc's bearing branches, and the number of bearing branches' flowers, ovaries' diameters and the percentage of foliate flowers are analyzed.
Comprehensive discrimination was conducted with 75 jujube cultivars existent in northern Shaanxi and 13 character indices, resulting in 16 preferred cultivars for the initial selection, including 6 cultivars for making dry fruit, 5 for fresh consumption and another 5 for both types of usage.
The variance analysis shows that variations of all the morphologic traits within population are significant,and significant differences exist in 5 character indices among populations(α=0.05),which may result from genetic and environmental factors.
For 31 varieties of alfalfa from domestic and abroad, the correlation coefficient and the partial correlation coefficient between canopy temperature and agronomic character indices during branching period to pod forming period was computed by using correlative analysis technology.
In addition, a worker characteristic index that combines percentage White, percentage married, and average age of workers shows surprising effects on the percentage of women in sales occupations.
Assume that the characteristic index α of stable distribution satisfies 1 >amp;lt; α >amp;lt; 2, and that the distribution is symmetrical about its mean.
This paper presents a trend coefficient as a characteristic index with which to investigate the 1951-1998 secular trend variation (STV) of northern 500-hPa height on a seasonal basis.
An approach based on the characteristic index elements, the correlation diagrams of some of the elements interested, and the abundance patterns of some of rare earth elements is valid for clarifying the different source regions.
A dimensionless stick-slip number η = √8U1h2/(kθRs2) was defined, which can serve as a characteristic index for the appearance of nano/microtribology stick-slip behavior.
We illustrate marker assisted analysis of genetic differentiation with a sample of RFLP and isozyme data from 111 accessions of rice lines and compare it to morphological differentiation based on Cheng and Wang' morphological character index.
You can specify a character index, using the north_arrow tag's charIndex attribute, if you want to change the North arrow symbol.
