Green part

July, at the commencement of flowering. The stems now preponderated, and the green parts of the plant showed a smaller percentage of essential oil, whilst the young flowers already contained a larger proportion of essential oil. 

It is thus apparent that at the commencement of vegetation of the peppermint the oil is rich in menthol, hut only a small amount is present in the esterified condition. Menthone only exists in small quantity. As the green parts of the plant develope, the proportion of esterified menthol increases, as has heen found to be the case with other alcohols. This esterification, however, only takes place in the leaves, and when the essential oil extends towards the flowering tops, it becomes poorer in esters. 

These observations throw light on the mechanism which governs the transformation in the plant of the compounds belonging to the menthol group. This alcohol being produced simultaneously with the green parts of the plant, is partially esterified in the leaves the esterification here... 

Pectins occur naturally in both soluble and insoluble forms. Soluble pectin occurs in plant juices and is particularly abundant in those juices which form jellies, such as black-currant and gooseberry. Insoluble pectins tend to occur in the green parts of plants, in fruit and in root crops.1 This insolubility is apparently due either to the presence of the pectin as its insoluble calcium or magnesium salt or because it is combined (esterified ) with cellulose or some other insoluble polysac-... 

This is an interesting result, as with an absorption maximum in the blue-green part of the spectrum that is close to but not coincident with an absorption maximum in the spectrum for chlorophyll (see Figure 2.2).

Lignocellulose is the fibrous material that forms the cell wall of a plants architecture . It consists of three major components (Fig. 2.1) cellulose, hemicellulose and lignin [3, 14-16]. It contrasts with the green parts of the plants and the seeds, which are rich in proteins, starch and/or oil. 

Air, water, soil, and food are all unavoidable components of the human environment. Each of those elements influences the quality of human life, and each of them may be contaminated. Food is not only the elementary source of nutrients, but may also contain natural chemical substances with toxic properties, e.g., cyanogenic glycosides (many plants), solanine (green parts of potatoes, sprouted potatoes, and potatoes stored in light), industrial pollutants (heavy metals), biogenic amines (fish), or mycotoxins (moldy foodstuffs). 

Birds that breed in cavities and reuse their nest sites often incorporate green parts of aromatic plants into their nests. Starlings, Sturnus vulgaris, prefer certain species of plants to others. House sparrows. Passer domesticus, incorporate neem (margosa) tree, Azadirachta indica, leaves into their nests. Extracts from neem leaves repel arthropods and inhibit oviposition (Sengupta, 1981). The aromatic plants are thought to fulfill an important function by keeping down populations of microbes in the birds nests (Mason and Clark, 1986). 

Site of alkaloid formation, transport, and accumulation. QA are formed in the aerial green parts of legumes, especially in the leaves (.9) In lupin leaves we succeeded in localizing the key enzymes of QA biosynthesis in the chloroplast (10, 11), where the formation of the precursor lysine also takes place. Like most of the processes that are located in the chloroplast, QA biosynthesis is regulated by light (.8) and QA formation fol lows a light-dependent diurnal rhythm (, 13). The alkaloids formed in the leaves are translocated via the phloem (13, 14) all over a lupin plant, so that all plant parts contain alkaloids. QA are accumulated and stored preferentially in epidermal and subepidermal tissues of stems and leaves (15, 16). Especially rich in alkaloids are the seeds, which may contain up to 5% (dry weight) alkaloid (equivalent to 200 mmol/ kg). ... 

Groups of Ti bearing minerals have been studied by Gaft et al. (1981) and the broad bands in the blue-green part of the spectriun have been connected with individual TiOe luminescence centers and their clusters, while the yellow band was ascribed to a Ti " center (Fig. 4.36). 

It usually generates the broadband luminescence in the UV-green part of the spectrum. 

In our study we found that H3, H4, S2 and S3 centers are characterized by relatively broad bands with A ax at 520-545 nm, sometimes accompanied by very weak zero-phonon lines at 489 and 523 nm (S2), 498 (S3) and 503 (H3) nm. It is very difficult to distinguish between the centers of this group, especially when they present together. Under pulse laser excitation the decay time differences enable more definite recognition. Different decay components in the green part of the spectrum allow us to establish the presence of H3 (12 ps) and S3 (126 and 213 ps) centers. These broad bands are sometimes accompanied by narrow lines of GR1 center at 794 nm and by system at 700 and 788 nm (Bokii et al. 1986 Davies 1994). The relatively broad fine at 463 nm with a decay time of 312 ps appears which is not described in the hterature (Fig. 4.72). 

We see that all parts have a green part status except for the resistor, which has a red part status. This shows that all parts except for the resistors have consistent information in the schematic and the database. In the next section we will show how to correct this problem with the resistor. Type CTRL-F4 to close the Part Manager window. 

If you now close the schematic, open the Part Manager, and then update the status as shown in section 10.C.3, you will see that all parts are displayed with green part status, indicating that the schematic is consistent with the database ...

Parsley seed oil is obtained by steam distillation of ripe fruits of parsley. It is an almost colorless to amber-yellow liquid whose dry odor is characteristic of the crushed fruit, but different from that of the green parts of the plant.
