life table parameters of aphis pomi degeer (hemiptera: aphididae) were determined on two host plants: apple (malus pumila l.) and flowering quince (chaenomeles japonica lindl.). this study was carried out under laboratory conditions (25 ± 1 ºc and rh of 70 ± 5 % and a photoperiod of 16: 8 h (l: d). the survivorship from first instar nymphs to adult was very close in m. pumila and c. japonica. t...

Abstract Background Plants have remarkable diversity in petal colour through the biosynthesis and accumulation of various pigments. To better understand mechanisms regulating pigmentation Lonicera japonica , we used multiple approaches to investigate changes carotenoids, anthocyanins, endogenous hormones gene expression dynamics during transitions, i.e., green bud petals (GB_Pe), white flower (...

Two new triterpenoids namely, 3α-hydroxyferna-7, 9(11),22-trien-12-one (1) and 3α-acetoxyferna-7, 9(11)-dien-22-ol (2) along with two known compounds 3α,16α-dihydroxyferna-7,9(11)-dien-12-one (3) and 3α,16α-dihydroxyferna-8-en-11-one (4) were isolated from Lonicera quinquelocularis. Their structures were elucidated by chemical and modern spectroscopic techniques. All the compounds showed good a...

Honeysuckle (Lonicera japonica Thunb.) is a traditional Chinese medicinal crop and belongs to the glycophyte with certain salt tolerance. This study aimed deeply dissect its adaptability by contrasting photosynthesis, photoinhibition oxidative damage under moderate severe iso-osmotic (150 300 mM NaCl) drought (19.3 % 28 PEG-6000) stresses hydroponic protocol. Photosynthesis was more susceptible...
