Sentence examples for fertilization values from inspiring English sources

To exclude the effect of normal die off that occurs during the first two weeks post fertilization, values were adjusted such that day 15 values represent 100% survival.

Nevertheless, it is common practice for farmers to estimate the fertilization value of manure by considering a small part of organically bound N and a reduced effectiveness of the mineral N (Kirchmann 1985), the latter in order to allow for gaseous and/or leaching losses at application and during the growing season.

Third, the assessment of the consequences of the deviations between individual fertilization success values and sperm competittive ability values.

With an ample 180-s time period for sperm to find and fertilize ova (see mean fertilization success values on Fig. 2), sperm from farm and wild males showed similar levels of fertility, either with wild (t1,17 = 0.214, P =  0.832) or farm eggs (t1,17 = 0.664, P =  0.511).

Fertilization success values render biased sperm competitive ability values.

For example, under the conditions described in the methods, heritabilities of sperm competitiveness calculated in full-sib experiments of around 0.6 will be on average estimated as being 0.3 because of the deviations that fertilization success values impose on the real sperm competitive ability values.

Every single value of sperm competitive ability can generate a wide range of fertilization success values as a result of variation in the sperm competitive ability of rival males (Figs. 1A and 1B).

The levels of SFR were lower for treatments where the applied sewage sludge doses were equivalent to four and eight times the normal doses of N mineral fertilization, reaching values of 1.7 × 1018 and 1.24 × 1018 spins g−1 HA, respectively.

Simulations of mating trials performed in the context of sibling analysis indicate that the heritability of sperm competitive ability is dramatically underestimated when fertilization success values are used.

The difference between the intraclass correlation coefficient for s2- Offspring and for F2- Offspring would therefore inform on how the estimations of additive genetic variance in sperm competitive ability are affected by the relative nature of fertilization success values.

In general terms, random extraction of males from the population together with the use of large sample sizes to calculate fertilization success values are advisable to minimize random effects influencing the degree to which fertilization success does not reflect sperm competitiveness.
