Effect of chitin on growth and chlorophyll content of two medicinal plants
The effect of chitin soil amendment was studied in the characteristics of organic glasshouse cultivation of the lemon balm and tarragon plants. Chitin in the peat substrate did not affect the length and weight of the lemon balm plant, while at the peat-sand substrate it increased the corresponding sizes and the total chlorophyll content. In the peat-sand and chitin substrate the increase of the characteristics...

Development of some high yielding rice lines tolerant to drought stress conditions
In Egypt, water requirement for the rice crop is a problem because of the limited irrigation water available from the River Nile. To solve that problem, a breeding program for drought tolerance, starting from hybridization until yield trials experiments, was designed. Ten promising lines were derived from IET 1444/ Sakha 102, Sakha 101 / IR 65600 and Sakha 101 / Gaori populations. Attentions were paid to the traits more...

Evaluation of allelopathic action of some selected medicinal plant on lettuce seeds by using sandwich method.
Laboratory experiments were conducted to evaluate allelopathic action of fourteen selected medicinal plants of semi-arid plain areas on lettuce growth through Sandwich method. Toxic (inhibitory) and non-toxic (stimulatory) effects were assessed by recording their effect on germination, radicle and percentage growth of hypocotyl. Both were examined for hypocotyl growth of lettuce seeds under the influence of leaves....

Modeling of the individual leaf area and dry weight of oregano (Origanum onites L.) leaf using leaf length and width, and SPAD value
The study was aimed to modeling of the individual leaf area and dry weight of oregano (origanum onites L.) using leaf length, leaf width and SPAD value. Non-destructive approach of modeling can be very useful for plant growth estimation. To predict individual leaf area and dry weight of oregano, models were developed using leaf length, leaf width, SPAD value, and different combinations of these variables....

Effects of Camellia sinensis and mixed probiotics on the growth performance and body composition in broiler
This study was conducted to investigate the effects of green tea and fermented green tea probiotics on the growth performance and body composition in broiler chicks. A total 168 Ross broilers chicks, one-day old was randomly allotted to 6 treatments with 4 replications having 7 layers per replication. There were six dietary treatments namely negative control (without antibiotics), positive control (basal + 30 ppm...

The quantitative effect of the temperature and light intensity at growth in Origanum onites L.
The study was aimed to define the relationships between temperature, light intensity and growth parameters. Namely, net assimilation rate, relative growth rate, leaf weight ratio, leaf area ratio and specific leaf area for oregano (Origanum onites L.). The quantitative effects of temperature and light intensity on growth parameters were examined in greenhouse-grown oregano plants. All equations produced for growth...

Micropropagation of Polygonum acre Kunth var. aquatile (Mart.) Meisn, and seasonal variation of tannins in acclimatized plants
A protocol for in vitro clonal propagation of Polygonum acre Kunth var. aquatile(Mart.) Meisn. is described as an alternative method to standardize raw material for production and experimentation. Disinfected nodal segments were inoculated into Murashige and Skoog basal medium (MS) and initially subcultured in the same kind of medium. They were then transferred to solid MS medium supplemented...

RAPD profile for the assessment of genotoxicity on a medicinal plant; Eruca sativa
Eruca sativa (Family: Brassicaceae) has gained an importance as a vegetable and spice, especially among Europeans. The genotoxicity of three heavy metals, viz. Zn, Pb and Cd was studied on E. sativa which showed a dose-dependent effect on radicle and coleoptile lengths. The radicle length was more affected as compared to coleoptiles length under all tested concentrations. The ranking of genotoxic...

Improved shoot organogenesis and plant regeneration of Echinacea angustifolia DC
We established an improved method for shoot organogenesis and plant regeneration from stem cultures of Echinacea angustifolia DC. The regenerated shoots obtained from stem cultures on solid MS medium containing different concentrations of BAP and kinetin. The highest number of shoots per explant (3.2) and shoot length (1.3 cm) was obtained on MS medium containing 2 mg/l BAP. The addition of auxins in MS...
