Abstract. A study was conducted at four Village Development Committees (Masuriya, Udashipur, Basauti and Pahalmanpur) of Kailali dis- trict, Far western Region, Nepal in 2016/17 to find out the effect of different storage materials on the seed moisture content and germination percentage of wheat. Seeds of wheat were packed using five storage materials (metal seed bin, earthen pot, purdue improved crop storage / Pics/ bag, gunny bag and super grain bag). The stored seed samples were drawn at three-month intervals starting from May 2016 to January 2017. The experiment was arranged in Randomized Complete Block Design (RCBD) in four replications. The results of analysis of variance revealed that the effect of storage materials was significant (P≤0.05) on seed moisture content and seed germination of wheat. After nine months of storage, the seeds stored in Pics bag recorded the lowest moisture (13.3%) and temperature (26.4°C), and the highest germination percentage (91.75%). The lowest quality performance (high moisture and temperature, low germination) of stored seeds was observed in an earthen pot. From the results obtained, it was concluded that wheat seed could be stored for a long time in Pics bag without deteriorating its quality parameters.

 

Possibilities for application of plant promotor Immunocitofit in integrated pepper production

Abstract. The effect of multi-objective promotor Immunocitofit on the germination, germinating energy, yield and degree of infestation as a result of Verticillium wilt was studied in treatment of pepper seeds and plants variety Kurtovska kapiya 1619. The experiment was performed both in laboratory and in open field conditions in the Maritsa Vegetable Crops Research Institute, Plovdiv during the period 2008-2009. Immunocitofit has stimulated the mass germination of the seeds and increased their germination ability. The yield obtained from such plants (treated seeds + threefold treatment during the vegetation: in bud formation phase + twofold treatments every 15 days with addition of 0.5 % kristalon 18, 18, 18) is higher, by 23.54 % on average compared to untreated control. A dominant power of effect (64.51%) on the variability of the character showed the year (growing conditions) followed by the production system (24.62%). The index of damage caused by Verticillium wilt is the lowest also in the variant with treated seeds and plants by the scheme + kristalon (i = 7.78%) and the highest in the untreated control variant (i = 29.96%). All systematic factors have an effect on the expression of this character. The growing system has the greatest effect (40.99%) on the expression of this character, followed by the factor seed treatment (29.33%) and the interaction treatment of seeds x growing system (25.08%).

Application of different nacl concentrations on seed germination of flax (linum usitatissimum l.) Cultivar

This investigation was conducted at the Field Crops Department, Agriculture Faculty, Namik Kemal University Tekirdag, Turkey. The present
research has studied the effects of NaCl of different concentrations on some characteristics of germination of flax. One flax (Linum usitatissimum L.) variety
(Raulin) has been studied under four salinity treatments, including, 0, 50, 100 and 150 mM in the laboratory conditions. In the experiments, germination rate,
plant fresh weight, hypocotyl and radicula length for all genotypes were decreased at the increase of salt dose. The evaluated flax variety was significantly
different for germination speed and radicula length. Although the highest germination speed was recorded in 100 mM (100.0 %), 0 mM and 50 mM salt doses
had the highest values for hypocotly and radicula length.
