Taking two-year-old peach tree of cv 'Chunjie' as test material, the natural inducing factors of peach bud dormancy and the roles of Ca2+ in the dormancy induction were studied. The results revealed that peach plant was very sensitive to short sunlight and/or natural low temperature. These two factors could induce growth cessation, dormancy, and(More)
The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) in 30 water samples and 5 tissues (gill, liver, brain, kidney and muscle) of 36 fishes which were collected from 18 typical lakes of the Daqing lakes group, China were measured between February and April 2012. The results of PAHs concentrations in the water showed that the range of total(More)
Taking the 6-year-old peach "Shuguang" as test object, this paper studied the effects of short-term heating at 40 degrees C, 45 degrees C, and 50 degrees C on the bud livability, bud burst, reactive oxygen content, and activities of related enzymes in peach bud, aimed to investigate the regulation effect of short-term heating on the endodormancy release of(More)
High chilling requirement grape (Vitis vinifera-V. labrusca cv. Summer Black) was used to evaluate its dormancy under short sunlight day (SD), long sunlight day (LD) and natural condition (CK). The results indicated that grape bud dormancy could be induced by natural low temperature and short sunlight alone or together. Short sunlight was the main(More)
The effects of three canopy shapes, i.e., vertical canopy, V-shaped canopy and horizontal canopy, on canopy microenvironment, quality of leaves and fruits were studied in the 3-year-old grape 'Jingmi' grafted on ' Beta' in greenhouse. The results showed that gap fraction and openness of vertical canopy were significantly higher than that of V-shaped canopy(More)
