As a result, the characteristics of the leaf epidermis of eight medical plants are very different from each other, for example, non-glandular hair, the shape, size and density of stoma, glandular hair and spot, etc.
The results of Na + and Cl - contents in the leaf secretion and inside the leaf showed that the glandular hair executed the function of salt_secretion, and when treated with the salt gland inhibitor the salt_secretion process was inhibited. As a result, Na + and Cl - were mainly accumulated inside G.
soja leaves. The results of Na + X_ray microanalysis under different salinities proved that the three cells of the glandular hair, especially the top cell, possessed strong competence for Na + accumulation.
The appropriate time for the researcher to study the density of glandular trichome on the leaf surface was during the lower leaf grows to its 40-50 days, the lumber leaf grows to its 50-60 days and the topper leaf grows to its 60-70 days.
Some genotypes of high trichome density were identified: K346, Nongda202, 8502, K149, NC628, 6388, Jinxing6007, K358. Some high trichome density genotypes were stable between two years: K346, NC628, K149, K358.Correlation analysis has been done between glandular trichomes density and leaves surface exudates weight per unit area of two years.
The results showed that stoma exists only on the lower epidermis and its distribution is irregular, and leaf epidermis consist of epidermis cells, stoma complexes and bushy trichomes including glandular hair and non-glandular hair.
Strong activity of β-glucuronidase first appeared in the epidermal and glandular hair cells of leaf primordia regenerated from callus of Scutellaria baicalensis Georgi.
Leaves predominantly accumulated β-glucuronidase in both glandular hair cells and mesophyll cells.
Glandular hair formation and resin secretion inEremophila fraseri F.
Each glandular hair secretes about 0.2 μg resin, which constitutes 17% of the mature leaf dry weight.
However, the beetles could not attach properly to surfaces covered with wax crystalloids or glandular hairs.
Leaf primordia matured rapidly in culture to form shoots within 1 month in which both the mesophyll cells and the glandular hairs were deeply stained.
Effects of three AM fungi on growth, distribution of glandular hairs, and essential oil production in Ocimum basilicum L.
The effects of colonization by three AM fungi, Glomus mosseae BEG 12, Gigaspora margarita BEG 34, and Gigaspora rosea BEG 9 on shoot and root biomass, abundance of glandular hairs, and essential oil yield of Ocimum basilicum L.
tarijense have numerous four-lobed glandular hairs on their leaves and were resistant to the flea beetle attacking potato crops near Lima, Peru.
Various morphological structures were found to appear on the callus surface in the following order: trichome (on the 2nd day), roots (the 2nd or 3rd day), embryoids (the 6th to 8th day), and buds (the 10th to 14th day).
It was found that amounts of trichome, which possessed multicellular structure with the average length of 160 μm and with an average diameter of 28 μm, existed in the frond ofP.
vittata, and the density of trichome on the pinnate axial surface was higher than that on the petiole.
Visible X-ray peak of As was recorded in the epidermal cell and trichome.
The relative weight of As in the pinnate trichome, which contained the highest concentration of As among all tissues of the plant, was 2.4 and 3.9 times as much as that in the epidermal and mesophyllous cells, respectively.
