Cucumis sativus is a vegetable crop belonging to the Cucurbitaceae family and originates from temperate, subtropical sub-humid areas. This study was aimed to evaluate the effect of water extract of immature melon seeds in inhibition of seed germination of cucumber and celery plant. This study was conducted in the laboratory of the Department of Science, Faculty of Basic Education, Diyala University, Iraq. The seeds of these vegetables were selected and diagnosed in the herbaceous plant in the Department of Life Sciences. During the washing of immature seeds that were isolated from other melon residues. The results showed that the concentration of (0.1, 0.3, 0.7) and compared to the comparison models had the same effect in germination in seeds for cucumber. For celery plant only (0.7) gave the highest percentage of inhibition of celery seed plant and reached 20% Which was 80%. As for the length of the root only, the concentration of (0.7) gave the lowest rate for the cucumber and celery which amounted to 2.132 and 0.866 respectively, compared to the comparison treatment amounted to 5.932 and 1.399 respectively, in addition to other transactions. In addition, the concentration (0.7) gave the lowest length of the cucumber and celery time of 8.799 and 2.566 respectively, compared with the comparison treatment given to both plants 13.232 and 3.066 respectively, in addition to other treatments. As for the soft and dry weight of the cucumber plant, the concentration was given (0.7) the highest rate of soft weight at 0.2920, while the concentration (0.1, 0.3) gave 0.2057 and 0.0599 respectively, while dry weight gave the concentration (0.7).

Combinational traits of seed size and seed-coat hardness in Citrus garrawayi (F.M.Bailey) (syn. of Microcitrus garrowayi) were investigated as markers for estimation of seed morphological and physiological maturity. Seed size (length) and coat hardness correlated well with changes in seed coat and embryo morphological development, dry-weight accumulation, decreases in moisture content and a significant increase in germinability. Seed moisture content decreased from 82 ± 1% in immature seeds to 40 ± 1% at seed maturation. The outer integument of immature seeds consisted of thin-walled epidermal fibres from which outgrowths of emerging protrusions were observed. In comparison, mature seed coats were characterised by the thickening of the cell walls of the epidermal fibres from which arose numerous protrusions covered by an extensive mucilage layer. Immature seeds, with incomplete embryo and seed-coat histodiffereniation, had a low mean germination percentage of 4 ± 4%. Premature seeds, with a differentiated embryonic axis, were capable of much higher levels of germination (51 ± 10%) before the attainment of mass maturity. Mature seeds, with the most well differentiated embryonic axis and maximum mean dry weight, had the significantly highest level of germination (88 ± 3%).

Albino Grifola frondosa (Dicks.) Gray “maitake” mushrooms (described as G. albicans Imazeki and then placed in synonymy with G. frondosa) are particularly rare, and the few pertinent records are not treated in scientific publications. A field investigation carried out in Sicily (Italy) led to the collection of an unusual white Grifola specimen at the base of a living tree of Quercus pubescens Willd. s.l. The outcome of sequencing the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) indicated that it belongs to G. frondosa and provided an insight to the phylogenetic relationships within the genus. The results of nutritional composition analysis showed that the albino basidioma possesses relatively high contents of Ca, Fe, K, and Cu and is rather low in Na when compared with literature data on edible mushrooms. Vitamin (B1, B2, B3, B5, B9, and D2) contents ranged from 0.15 to 3.89 mg per 100 g of mushroom dry weight. The cold-water extract of this specimen was effective at inhibiting the growth of Staphylococcus epidermidis ATCC 12228 and Pseudomonas aeruginosa ATCC 15442 at the maximum screening concentration of 50% v/v. In addition, the extract slowed down the ability of Staphylococcus aureus ATCC 43300 to form biofilms. According to data hereby reported, the albino G. frondosa is a culinary-medicinal mushroom with a promising exploitation potential.

Copper content and growth of excised hydrilla [DioeciousHydrilla verticillata(L.f.) Royle # HYLLI] apical shoot segments were determined following exposure to copper sulfate (CuSO4), copper-triethanolamine (Cu-TEA), and copper-ethylenediamine (Cu-EDA). For all copper formulations, inhibition of growth was related to the amount of copper associated with the excised shoots. At equal copper exposure, the Cu-EDA formulation produced the greatest inhibition of growth and generally the highest copper levels in the plants. The Cu-EDA formulation inhibited dry weight gain by more than 80% 3 weeks after a 2-h exposure to 2.0 or 4.0 ppmw copper. Under similar conditions, CuSO4or Cu-TEA produced 60% inhibition. The presence or absence of light during a 2-h exposure had no effect on the efficacy of uptake of copper from any of the formulations. Formulation-dependent differences in the mechanism of copper uptake is suggested because rinsing of exposed shoots with dilute acid (0.01N HNO3) removed copper from shoots treated with CuSO4or Cu-TEA but not from those treated with Cu-EDA.

To evaluate probable allelopathic effect of water extract originated from different parts of russian knapweed (Acroptilon repens L.) on growth of purslane (Portulaca oleracea L.), a factorial experiment was conducted based on randomized complete block design with three replications at greenhouse condition in 2011. Treatments were water extract concentrations (0, 5, 10, 15 and 20 percent) obtained from different part of russian knapweed (aerial part, flower and root). Results showed the significant effect of extract type on seedling length, and extract concentration on shoot length, root length and seedling length. Interaction effect between extract type and concentration on the ratio of root/shoot length, seedling fresh weight, seedling dry weight and germination percentage was significant, too. Means comparison indicated that the longest root (3.55 cm), shoot (4.65 cm) and seedling (8.20 cm) were obtained from control treatment, reducing with higher concentration of extract. The longest shoot (6.95 cm) belonged to extract originated from russian knapweed flowers. The highest ratio of root/shoot length (0.73), seedling fresh weight (0.61g) and seedling dry weight (0.044 g) belonged to control treatment. In general, increasing of extract concentration caused in reduction of germination and seedling traits. Meanwhile, extracts of aerial part had more sever reducing effect than root and flower extracts.

SummaryEighteen foetal sheep were used to study the relationship between suboptimal growth and linear size of skeletal units, dry weights of representative muscles and muscle histology. Foetuses with suboptimal growth caused by inadequate maternal nutrition and competition with other foetuses showed a decrease in skeletomuscular growth although allometric growth was not affected. A slight correlation (r =0·14, P < 0·005) existed between dry weight of the longissimus dorsi and mean minimum myofibre diameter. On morphological evidence, myofibre hyperplasia was thought to be complete by approximately 80 days gestation in all foetuses. Increases in the number of myofibres crossing mid-length transverse sections of the sartorius occurred after this time but were thought to be due to intrafascicularly terminating myofibres growing in length. Suboptimal muscle growth of foetuses in the latter third of gestation was thought to be associated with an inhibition of growth in length of intrafascicularly terminating myofibres.

The mistletoeLoranthus parasiticushas been used as a compound for traditional medicine in Northeast Asia for a long time and is known to possess neuroprotective action. Nonetheless, the effect ofLoranthus parasiticuson allergic responses remains unknown. In the present study, we evaluated whether the water extract ofLoranthus parasiticus(LPE) could inhibit IgE-mediated allergic responses in RBL-2H3 cells. LPE inhibited the release ofβ-hexosaminidase (IC50, 184.5 μg/mL) and the formation of tumor necrosis factor-α(IC50, 84.27 μg/mL), interleukin-4 (IC50, 93.43 μg/mL), prostaglandin E2(IC50, 84.10 μg/mL), prostaglandin D2, and leukotriene C4(IC50, 43.27 μg/mL) in a concentration-dependent manner. Moreover, LPE inhibited phosphorylation of Syk, PLCγ1/2, PKCδ, ERK, JNK, p38, and Akt. In the late phase, LPE decreased 5-lipoxygenase phosphorylation and COX-2 expression but not cPLA2phosphorylation. Additionally, LPE included total phenolic compounds (10.72 mg/g dry weight) and total flavonoids (56.20 mg/g dry weight). These results suggest that the phenolic compounds or flavonoids contained in LPE may be associated with antiallergic activity. The phenolic compounds and flavonoids in LPE are antiallergic phytochemicals capable of inhibiting the activation of the FcεRI signaling cascade in mast cells. Such effects may provide further information for the development of a phytomedicine for allergic diseases.

The autointoxication of chrysanthemum was studied using water extract of Dendranthema morifolium's rhizospheric soil. Results of bioassays showed that the water extract inhibited chrysanthemum seed germination and the activities of some important root enzymes. The seedling nitrate reductase activity was decreased linearly with increasing concentration of the extract. The activity of root dehydrogenase was inhibited only at the highest concentration tested [3.2 g·mL-1, dry weight (DW)], but was stimulated at a lower concentration tested (1.6 g·mL-1, DW). Malondialdehyde content increased at higher than 1.6 g·mL-1, DW concentrations of the extract. The autointoxication phenomenon might be related to the difficulties in continuous plantings of chrysanthemum at the same location.
