[Effects of flood stress on anthocyanins synthesis with relative enzymes and genes of Chrysanthemum morifolium cv. 'Hangju'].

The study is aimed at determine the content of anthocyanins and expressions of relative genes and activity of relative enzymes. The effects of flood stress on anthocyanins synthesis with relative genes and enzymes of Chrysanthemum morifolium cv. 'Hangju' were analyzed.

[Study on winter dormancy of Thesium chinense and its phenological phase].

In order to explore reasonable artificial cultivation pattern of Thesium chinense, the biological characteristics and nutrients change in the process of winter dormancy of T. chinense was studied. The phenological period of T.

[Identification of chemical signals and haustorium induced of Thesium chinense].

To separate and identify chemical signals which induce Thesium chinense haustorium formation, the components of T. chinense roots secretion collected with XAD-4 resin were detected by GC-MS. The effect of DMBQ as exogenous signals to induce haustorium formation in T.
