Effect of mechanical scarification, dry heat, hot water, and sulphuric acid on the germination behavior ofCistus populifoliusL. (rockrose) was studied. Untreated seeds after 60 days of incubation germinated less than 7%. After thermal treatments, 90% germination was achieved, and sulphuric acid pretreatment gave 61% germination. Soaking in distilled water did not increase germination, but scarification of the seed coat gave 57%. Hardness and impermeability of the seed coat appear to cause deep dormancy inC. populifoliusseeds.

Effect Of Chlorine

Effect of chlorine, potassium permanganate and peracetic acid pretreatment on H2O2 bleaching properties of cotton stalk SCMP was studied in the paper. The results showed that brightness gradually increased with dosage of chlorine, however, the increase is small, and bursting index and breaking length firstly increased and then decreased as dosage of chlorine is great than 1.5%. Brightness of H2O2 bleached pulp decreased for potassium permanganate pretreatment, even change the bleaching sequence. Brightness of PaPP bleaching is the highest with peracetic acid pretreatment. Among the studied reagents, chlorine and peracetic acid can increase brightness of H2O2 bleaching, however, pretreatment with potassium permanganate can not improve bleaching properties. The brightness with CH3COOOH pretreatment is higher than that of chlorine pretreatment.
