Development at the paintings of illustrators of the previous, starting from Elizabeth Blackwell, whose drawings helped to unlock her husband from debtors' felony, via to the phenomenal medical drawings of Beatrix Potter, this booklet offers with either the sensible paintings and the comparable botany of the topic. beginning with an advent to uncomplicated botany; this consultant subsequent covers education of plant fabric for drawing and using pencils, watercolors, coloured pencils, and pen and ink; and finishes with correcting blunders and completing touches and advised issues for extra research.

Changes in the utilization pattern of primary substrate, viz. [U-C-14] acetate, (CO2)-C-14 and [U-C-14] saccharose, and the contents of C-14 fixation products in photosynthetic metabolites (sugars, amino acids, and organic acids) were determined in Fe-deficient Java citronella in relation to the essential oil accumulation. An overall decrease in photosynthetic efficiency of the Fe-deficient plants as evidenced by lower levels of incorporation into the sugar fraction and essential oil after (CO2)-C-14 had been supplied was observed.
1994). In vitro plants of C. citratus were established, starting from shoot apices derived from plants cultivated under field conditions. The effect of the immersion frequency (two, four, and six immersions per day) on the production of biomass in temporary immersion systems (TIS) of 1 L capacity was studied. 3) was obtained when six immersions per day were used. 2 g) were obtained with a frequency of four and six immersions per day, respectively. 97 cm) were greater in the treatment with four immersions per day.
2001). In Java citronella significant positive correlations were observed between fresh matter, citronellol content, dry and fresh matter yields, and total essential oil content (Omisra and Srivastava 1994). 5, and 50 mm) and methods (ridge and furrow, and broad bed and furrow method) of irrigation acid nitrogen levels (0, 200, and 400 kg N ha−1 yr−1) were studied on herb and oil yields of Java citronella, highest herb and oil yields were achieved with the application of 400 kg N, maintaining 25 mm depth of irrigation, while the content and quality of oil were not affected either by irrigation or nitrogen (Singh et al.
