The emission levels were reduced under cloudy and rainy days, even at full blooming stages, prompting us to investigate whether light or circadian rhythm plays an important role in the production of floral scent in orchids.
The average composition of Albert's solution was (mg/l) N 83, P 30, K 124, Ca 106, S 226, Mg 20, Cu 0.02, Fe 1.0, Zn—0.1 and Mn 0.27 and Mo 0.05 and it was applied in concentrations 1.6 and 2.6 g/l during growing and blooming stages, respectively (Saparamadu et al. 2010).
Hypericum perforatum L. (Clusiaceae) samples were collected mid July 2007 from the mountain Čemernik, south of Serbia, at blooming stage.
In the alage blooming stage, the growth of algicidal bacteria was promoted by the nutrients that are organic materials released by the algae.
In the model, several different compositions of foam rubber can be mixed at the foam blooming stage, and products are processed at the manufacturing stage.
The maximum yield of dry and fresh herbage, yield and content of oil and thymol yield were obtained in 15 cm space and beginning of blooming stage.
NF consisted with two different nutrient formulations, NFG for growing stage and NFB for blooming stage having the composition (mg/l): NFG: N 313, P 80, K 202, Ca 300, Mg 78 and NFB: N 366, P 80, K 650, Ca 169, Mg 78.
Each ramet bore one to three capitula in the early blooming stage and the capitula of each host had approximately the same size.
At the blooming stage (D4), the floral scent profile predominantly consisted of the monoterpene linalool, β-ocimene, 1,8-cineole and sesquiterpene α-farnesene as well as methyl benzoate (Fig. 1c-g).
Artemisia annua essential oil was obtained from a Romanian variety of A. annua (ROMN 08), cultivated at the same site and under the same conditions as GERM07, but harvested when plants were in early to late blooming stage.
Given that petals are the main tissue for floral volatile compounds emission in H. coronarium [ 46], and the release amounts of these compounds at squaring stage (D1), blooming stage (D4) and senescence stage (D6) display significant difference (Fig. 1), petals at these stages were chosen for DGE profiling analysis.
