Carbon assimilation accumulation and partitioning was studied in one-year-old fruiting limbs of greenhouse-grown "Ruiguang 5" nectarine(Prunus persica L.var.nectarina Ait), affected by about 10%~12% shading treatment(simulating the light intensity decrease due to dust accumulation on greenhouse covering by adding old plastic film to it) during the second rapid swell of peach fruit growth.
In the period of fruit rapid growth, the fruit had higher competition for (NH_4)_2SO_4 , Gly and L-Glu than the leaf and lower for Ca(NO_3) under water culture and leaf labeled condition.
Studied on tissue culture and rapid propagation of Ageratum houstonianum Mill. The results showed that the best explant in tissue culture was leaf. The best media for each stages were as follows: (1) Callus inducing medium: MS+6-BA1mg/L+NAA0.5mg/L;
The top buds and axillary buds of Nepenthes mirabilis used as explants for tissue culture and rapid propagation were studied. The results showed that the young buds could be induced after 10 days cultured on the medium 1/2MS+6-BA 1mg/L+NAA 0.1mg/L.
In the early 90s ,with the rapid development of the Garden industry, individual breed of the grass for lawn couldn' t satisfy the need of the Garden constructing . People began to import a great many greed of grass for lawn from the foreign country.
Along with the rapid development of our country's urban construction,the traditional flood irrigation can't meet the needs of the irrigation of the modern lawns,and it is inevitable to adopt the high-efficiency irrigation model.
The use of time-frequency methods (phase space methods) allows the use of rough symbols of ultra-rapid growth in place of smooth symbols in the standard classes.
The pharmaceutical sciences are advancing rapidly in the post-genomic era of the 21st century with the completion of the human genome, as well as those of many other organisms including bacteria and parasites, and the rapid advances in proteomics.
The α-isomer exhibited rapid and significantly higher peak plasma concentrations in all the species post intramuscular administrations, while β-isomer showed prolonged plasma levels.
This suggests that the rapid initial reduction in percent parasitemia may be due to α- isomer and the activity is maintained by the β- isomer.
Flavonoid antioxidants act as scavengers of free radicals by rapid donation of a hydrogen atom.
