“…Compounds 3, 6, 9 and 11-19 were tested in ABTS radical-scavenging assays, as well as six compounds 3, 11, 13-15, 17 and 19 in DPPH radicalscavenging assays. Results show that phenols and coumarins (11)(12)(13)(14)(15)(16), MSE, and n-BE show relatively low antioxidant activity (IC 50 <20 g/ml); phenol compounds 12, 13 and coumarin 16 (1), 8-hidroxy-1-oxo-(14,15 eremophil-7(11),9(10)-dien-12,8-olide (2), 1-hidroxy-2-oxo- (14,15 eremophil-1(10),7(11),8(9)-trien-12,8-olide (3), Cytotoxic activity of sesquiterpene lactones was also shown in species Ligularia platyglossa (Franch.) Hand.-Mazz (Asteraceae) (8).…”

The research addressed the effect of gibberellic acid (GA 3 ) on growth and flowering of Ajania pacifica /Nakai/ Bremer et Humphries 'Bea'. The vegetative growth lasted for 8 weeks in glasshouse, under natural long day and from August 15 -under natural short day. The plants were divided into four groups: 1 -the plants sprayed with distilled water (control combination); 2, 3 and 4 -the plants sprayed with GA 3 ones, twice and thrice, respectively, starting from the 5 th week of growth, and then in the 6 th and 7 th week, successively. Each of the group was divided into two subgroups: the first one treated with GA 3 at concentration of 250 mg·dm -3 and the second with 500 mg·dm -3 . It was observed that double spraying with GA 3 accelerated the buds development of Ajania pacifica, thus shortened the cultivation time by about two days. Treatment with GA 3 at concentration 500 mg·dm -3 stimulated the elongation of shoots more than treatment with GA 3 at 250 mg·dm -3 . The plants sprayed twice were longer than the control and then those sprayed one time. However, elongation of shoots was not remarkable; corymbs were shorter, narrower, and contained lesser number of inflorescences. The present study indicates the specificity of the response of Ajania pacifica to GA 3 treatment, which appears to be different from other ornamental species.

“…Many wild species in genus Ajania have long been used as traditional Chinese medicine (Li et al 1999;Meng et al 2001) or ornamental foliage plants (Iwatsuki et al 1997;Zhao et al 2008) and are evenly promising groundcover plants (Zhao et al 2009). As a native species to China, A. przewalskii Poljak.…”

Reproductive barriers in the intergeneric hybridization between Chrysanthemum grandiflorum (Ramat.) Kitam. and Ajania przewalskii Poljak. (Asteraceae)

In order to reveal the causes of low seed set in the intergeneric cross between Chrysanthemum grandiflorum (Ramat.) Kitam. 'Zhongshanjingui' (female parent) and Ajania przewalskii Poljak. (male parent), we systematically investigated megasporogenesis and megagametogenesis of female parents, pollen germinability of male parents, pollen-pistil interaction and hybrid embryo development using paraffin section and light, fluorescence and scanning electron microscopy. The results indicate that development of megagametophyte of female parent belongs to Polygonum type and 84.6% ovules developed to normal 8-nucleate embryo sac at the stage of pollination; the pollen germinability in vitro of male parent was 39.3%; a large number of pollen grains germinated normally and no callose deposited on the female stigmas within 24 h after pollination. Furthermore, about 75% ovules were fertilized, whereas only 17.2% ovules developed to normal maturing embryos at 15 days after pollination due to abortion at various developmental stages. Taken together, these results suggest that sterile ovules of female parent, pollen viability and pollen-pistil interaction have no significant influence on seed set in the cross. A high percentage of embryo abortion or degeneration, i.e. post-fertilization barrier, may be the main factor for low seed yield.
