High temperature during seed set and seed filling can reduce yield and seed quality. In order to evaluate the effect of high temperature during PLANTing date and also PLANT density on soybean seed quality, an experiment was conducted at two locations, namely, Seed and PLANT Certification and Registration Institute in Karaj and Agricultural and Natural Resource Center of Moghan, in 2013. The studied factors were included PLANTing date (5th of May, 5th of June and 5th of July), PLANT density (300, 400 and 500 thousand PLANT/ha) and soybean varieties (Williams and L17) were sown in the rate of 40 PLANTs per m-2 at 5th May, 5th June and 5th July. The experiment was conducted as a factorial based on a randomized complete block design (RCBD) with three replications. The results of standard germination test showed that in Moghan area, the highest normal seedling percentage (92. 1%) was obtained at fifth of June and in Karaj area, it (96. 2%) was gained at fifth of July. In addition, it was noticed that cv. L17 in Moghan and cv. Williams in Karaj had the highest normal seedling percentage. The results of accelerated aging test was cleared that the normal seedling percentage in karaj was more than Moghan area and it showed that the quality of seed that were produced in Karaj was better than Moghan area. There was no significant difference between areas in 300 and 400 thousand of PLANT/ha and in these both density, the result of Karaj was better than Moghan area, but there was significant difference between normal seedling percentage after accelerated aging test in Karaj (77. 6%) and Moghan (58%) in 500 thousand PLANT/ha. The highest seedling vigor index (11. 75) was obtained in 400 thousand PLANTs/ha at fifth of July in Karaj area and the lowest rate of it (5. 41) was observed in 300 thousand PLANTs/ha at fifth of June in Karaj area.

This research was done during 2015-2016 as split-plot experiment as RCD with 3 replication in laboratory of Agriculture and Natural Resources Research Center, Zanjan. Sowing date of MOTHER PLANT as main-plot in 3 levels contained: D1: 7 Oct 2011, 2012 D2: 22 Oct 2011, 2012 D3: 6 Nov 2011, 2012 and 10 cultivars of MOTHER PLANT included: Opera, Ahmadi, KR4, GAo96 × Zarfam (1)(2), Okapi × GAo96 (2)(5), Orient × Modena (2)(4), Orient × Modena (5)(4), Okapi × GAo96 (2)(2), Okapi × GAo96 (5)(2) and GAo96 × Zarfam (5)(1) as sub-plots were considered that conducted in a two year experiments as split-plot as base of RCBD. The studied traits included: germination percent, time required for germination, germination rate, root length, shoot length, seedling dry weight. The result of variance analysis showed that sowing date and cultivar simple effect were significant on mentioned traits. Sowing date and cultivar interaction also was significant effect on mention characteristics. The mean comparison of sowing date and cultivar interaction on germination percent demonstrated that Opera, Okapi x GA096 (5)(2) and GA096 x Zarfam (5)(1) each with mean of 100% had the most germination percent in all sowing date. Generally, results revealed that delaying in sowing date resulted to decreased germination percent. Result showed that cultivars and lines that had the highest germination percent also had the longest root and shoot length.

Seed senescence is one of the major problems in the production of crops. In order to evaluate the effect of accelerated aging on germination and other seed germination components produced from the treated MOTHER PLANT in three bean cultivars, a factorial experiment was conducted in a randomized complete block design with three replications at the research laboratory of Faculty of Agriculture, Shiraz University. The factors were including pinto bean varieties at 3 levels includes E9, E10, and Khomain, accelerated aging at two levels includes accelerated aging and control, and the third factor was seeds produced from treated MOTHER PLANT seed in the farm at 7 levels includes: polyethylene glycol (PEG)-5 bar at 6 hours, , potassium chloride (KCl)-20 mM at 6 hours, calcium chloride (CaCl2)-15 mM at 3 hours, sodium chloride (NaCl)-20 mM at 6 hours, salicylic acid (C7H6O3) 500 mg per liter at 12 hours, distilled water at 12 hours and without pretreatment (Control). The percentage and rate of germination, seedling dry weight, weight and length vigor index and 9th day germination energy were measured. The result showed that the interaction between accelerated aging, pretreatment and variety on germination traits including germination percentage, seedling dry weight, weight and length vigor index and germination energy of the 9th day at 1 % level, interaction between accelerated aging and pretreatment on germination rate at 1 % level and interaction between pretreatment and variety on germination rate and coefficients of allometric at 5 % level were significant. Seed germination traits at accelerated ageing treatment was lower than control. The maximum germination percentage and germination energy of the 9th day was for sodium chloride at 6 hours and E10 variety, maximum seedling dry weight, germination rate and weight and length vigor index in calcium chloride (CaCl2) at 3 hours treatment and E10variety were detected. The result showed that according to the variety and selection of appropriate pretreatment of MOTHER PLANT, it is possible to improve storage and have seeds with higher power and less deterioration.

To evaluate seed vigor of marigold affected as organic, biological, nano and chemical fertilizers on MOTHER PLANT, a study was conducted in Research Center and Education of Agricultural and Natural Resources of Khorasan Razavi province. The seeds sowed in seedling trays and then seedlings were transPLANTed to the main land. PLANTs were under the impact of 10 fertilizer treatments contains Compost (15 ton/ha), Vermicompost (5 ton/ha), cow manure (15 ton/ha), Compost with Pseudomonas putida, Vermi compost with Pseudomonas putida, Nanobiologic fertilizer (1. 5 L/ha), Nano chalate ZFM (2 kg/1000 L), Nano composit Bioorganic (200 kg/ha), Chemical fertilizer (150N, 50P, 50K) and control. The experiment was conducted in a completely randomized design with 10 treatment with three replications. . At each one of treatments seeds after harvest transported to the laboratory and posed to germination test in germinator at temperature 20 ° C for 15 days. Then traits such as percentage and speed of germination, mean germination time, seedling length, seed vigor index and seedling dry weight were measured. The results showed that fertilizer treatments had significant effects on germination percentage, germination rate, mean germination time, seedling length and vigor index of Calendula officinalis seeds but had not on seedling dry weight. The highest seed germination was found in compost treatment that was 94% (24. 5% increment) and the lowest was seen in control treatment (76%). The highest germination rate was seen in compost treatment (6. 05) and the lowest was in control (2. 54). Application of compost in comparison to control showed 46. 06% reduction in mean germination time. Also using compost had the greatest germination rate in compared to control (more than 138%). Overall compost treatment showed the best performance on the seed and seedling traits of marigold.
