some reports indicated that terpenoides allochemicals material induced oxidative stresses during seed germination phase. α-pinnen, as one of important allechemical monoterpenoids, reported from species of several plant family and especially ferula flabelliloba from apiaceae. in order to investigate the allelopatic effect of f. flabelliloba and the time of sampling on physiological and biochemic...

Microbial inoculants are environmentally sustainable alternatives to petrochemical-derived herbicides, pesticides, and fertilizers in agriculture. We demonstrated the potential develop a commercializable Klebsiella variicola product with storage on-seed stability by encapsulating cross-linked alginate matrix (CLAM) powder spray drying. The microencapsulation drying (‘CLAM process’), an industri...

This paper is a preliminary report of in vitro studies comparing platelet storage in the new polyolefin PL732 packs with the present polyvinyl PL146 packs. The parameters used to assess platelet viability in these studies were the recovery from the hypotonic stress test (HST) and the pH. The effect of the mass of concentrate was assessed by preparing 20 g, 35 g and 50 g packs. The method of agi...

The relationship between molecules having granulocyte colony-stimulating activity (G-CSA), erythroid burst-promoting activity (E-BPA), and activity promoting increase in the number of granulocytic progenitors in liquid culture ( GPA) was explored in conditioned medium from human leukocytes (HLCM) and human placenta (HPCM). As tested on human hemopoietic progenitors in culture. G-CSA eluted from...

The objective of the present study was to evaluate the effects of light and temperature on germination of Cereus pernambucensis seeds, a species of columnar cactus native to Brazil and naturally incident in the restinga. Cereus pernambucensis seeds were incubated under different temperatures, from 5 to 45 °C, with 5 °C intervals, and under alternating temperatures of 15-20 °C, 15-30 °C, 20-25 °...

The caper (Capparis spinosa L.) is a perennial plant characteristic of the Mediterranean region that presents difficulties in its propagation, both vegetatively and by seeds. main aim this study to provide collection guidelines achieve viable commercial for which three experiments were undertaken determine viability germination different seed lots. In first experiment, own produced seeds (colle...

Seed dispersal of Guarea glabra and G. kunthiana (Meliaceae) in Monteverde, Costa Rica was studied to determine how seed predation and secondary dispersal affect the distribution of seeds available for recruitment. The arillate seeds are consumed mainly by birds that regurgitate or defecate the seeds intact. After dispersal, 45.6% of G. glabra and 26.6% of G. kunthiana seeds were buried 1– 3 cm...

An experiment was carried out at the Department of Field Crops laboratory, College Agriculture, University Tikrit, in order to know effect stimulating stored seeds triticale Farah cultivar by α -amylase enzyme using a complete random design (CRD) factorial experiment. The first factor storage periods 6 months, 1.5 years and 2.5 (S1,S2 S3) second concentrations 0 (dry seeds), soaked distilled wa...

Lettuce (Lactuca sativa L. cv Minetto) seeds were primed in aerated solutions of 1% K(3)PO(4) or water at 15 degrees C in the dark for various periods of time to determine the manner by which seed priming bypasses thermodormancy. Seeds which were not primed did not germinate at 35 degrees C, whereas those which were primed for 20 h in 1% K(3)PO(4) or distilled H(2)O had up to 86% germination. T...
