We studied the parental taxa and the interspecific reciprocal hybrids between Larix leptolepis with Larix gmelinii, using classical cytogenetic methods, as well as fluorescence in situ hybridization (FISH) and genomic in situ hybridization. A high frequency (>90%) of complete bivalent formation was observed in reciprocal hybrids. Less than 10% of pollen(More)
This paper, the effects of ABA, PEG400 and AgNO3 on the number of somatic embryos of Larix Principis-Rupprechtii were carried out by 311-A regression design. The regression equation was established which expresses the number of somatic embryos of Larix Principis-Rupprechtii as function, and the ABA, PEG400 and AgNO3 on as variable respectively. Using the(More)
New side chain-modified iodothyronines have been synthesized. They include: 1-[4-(4-hydroxyphenoxy)-3,5-diiodophenyl]-1,2-ethanediol (T2EG); alpha-hydroxy-4-(4-hydroxyphenoxy)-3,5-diiodobenzeneacetic acid (T2HAA) and their 4-methyl ether derivatives (MT2EG, MT2HAA); 1-[4-(4-hydroxyphenoxy)-3,5-diiodophenyl]-2-aminoethanol (T2EA);(More)
Larix principis-Rupprechtii is one of the superior afforestation forest trees growing in north China. Embryogenic cultures were initiated from immature zygotic embryos of Larix principis-Rupprechtii on S culture medium containing 2, 4-D 0-2.2 mg/L, KT and BA each at 0-0. 8 mg/L. Embryogenic calli were subcultured and multiplicated on S + B culture medium(More)
