This may simply reflect their geographic separation, but might also be due to a barrier to cross-fertilization. Experimental crosses have shown that the clonal lineages undergo self fertilization with equal frequency as out-crossing [ 25].
Santinato et al. (2008) observed that coffee trees fertilized with coffee husk plus mineral fertilizer had equal or higher yields than exclusive mineral fertilization.
The maximum number of fertilizations was equal to the number of optimized cuttings (i.e., three since three cuttings were optimized).
When each of the 25 stands per growing site was assumed to cover an equal area, the effect of fertilization on timber production was as shown in Fig. 9.
Successful fertilization rates were equal to or higher than 90% for about half of the strains used for crosses.
Two to three hours after fertilization, P. lamarckii embryos undergo equal spiral cleavage and subsequent divisions occur variably at 30 min to 1.5 h intervals.
If there is an excess of females, their steady-state abundance depends also on the steady-state fertilization fraction, which is just equal to the stationary male-to-female ratio R *.
Afterwards, CSeq(t) in year t equals NEP CP (t), assuming no CO2 fertilization and other climate feedbacks (as such, the NEP of the natural vegetation is about 0).
Other things being equal, the demand is unchanged by the CO2 fertilization.
Following ICSI, selected zygotes with successful fertilization (presence of two pronuclei (2PN) of equal size in the center of the ooplasm) were individually cultured in a Minc benchtop incubator at 5% O2, 6% CO2, 98% N2 until day 3.
Boveri's third report proved the theory introduced by Belgian cytologist Edouard van Beneden that the ovum and sperm cell contribute equal numbers of chromosomes to the new cell created during fertilization.
