field germination
1.2. The seed germination rate of different provenances of Toona sinensis was high. However, the rate of field germination rate was lower than seed germination rate and varied from 25.33 percent to 55.33 percent.
2.From the study, it can be recommended that soil amended with residential sludge (1:1) provide better field germination, growth and nodule formation of L. leucocephala in degraded soil.
4.With the typical water-base waste drilling fluid in Daqing oil field,authors carried out experiments of germination percentage of maize and soybean seedgrown in the field and germination percentage of soybean seed cultivated in pots todemonstrate the effect of waste drilling fluid upon crops.
5.The results show that 20% of tricyclazole and IBP and 30% of isoprothiolane have better effects for controlling Magnapothe grise in rice field. Three pesticides strongly control spore germination (only 0. 33%~1. 0% of spore germination rate).
6.In field experiments,BK B2 and B1+2 could not only promote germination of garlic seeds and growth of seedings,but also increase yield.
7.The results show that the non?aged seed has a higher vigor than the aged seed was low. The results corresponded to the germination rate in the field.
8.Incomplete diallel cross was made by CMS Shaan2A,PolimaA,1763A with four restoring lines 92 P 187 、Ken C 1、Ken C 8 and L 45 .Their F 1 generations as trial materials,under sclerotinose natural germination in field and artificial inoculation,survey identification disease index and disease incidence of combinations,the combining ability of parents and the combinations to disease resistance was evaluated.
9.gossipina remarkably, but different varieties had significant difference. Percentage of the conidia germination which were in the extracts or eluant of cotton leaves and bolls of Simian 2, Yanmian 48, Dai 15 and Zhongmian 12 was lower than others. The result was more or less indentical with that the lower disease index of victor boll or field inoculation.
10.Germination rate of ?Phoebe bournei? seed in the field is an index to evaluate seed vigor. The seeds artificially aged(38℃,100%RH,72 h)and seeds not artificially aged are used as different materials for vigor testing to find some reliable methods to determine the seed vigor of ?Phoebe bournei? simply and quickly for production.
