Two separate experiments was arranged in a randomized complete design in 4 replicates in order to evaluate agronomy aspects of cultivation and aim of evaluation effective treatments in breaking dormancy of native and valuable medicinal plant, Caper seeds (Mazdavand ecotype) and also to evaluate the best seed bed medium for germination of Caper seeds along with sustainable agricultural systems. Treatments in breaking dormancy test included control (distilled water), pre chilling (for 2 and 3 months), GA3 (250 and 500 ppm for 12 hours), KNO3 (0.2 and 0.5% for 12 hours), scarification with sandpaper (85%), seed coat removal, soaking in NaClO 0.5% for 5 minutes, scarification+250 ppm GA3, scarification+0.2% KNO3, scarification+250ppm GA3+0.2%KNO3. Treatments in evaluation the best seed bed medium experiment included control (soil of habitat), manure fertilizer, vermicompost and bio-fertilizer (phosphonitrokara). According to results of first examination, pre-chilling for 2 and 3 months were the best treatments for breaking dormancy (with 85% germination and 3.5 seeds per day germination rate). Also, results of evaluation the seed bed medium, showed that vermicompost had the highest germination percentage, highest number of leaves and the most seedling weight vigor index. Vermicompost and manure fertilizer had the highest leaf length, shoot length and seedling dry weight. Manure fertilizer and vermicompost, while creating sustainable agricultural conditions, increased the growth and improved morphological characteristics of the Caper medicinal plant seedlings.

Abstract Considering the importance of proper nutrition of mother plant in the production of seeds with high vigor, a factorial experiment was done in a completely randomized design with 3 replications to study the germination characteristics of artichoke seeds which harvested from mother plants treated with chemical and biological fertilizers, in 2013. Chemical fertilizer treatments consisted of three levels (100% chemical fertilizer, 50% chemical fertilizer and control), and bio-fertilizer consisted of 4 levels (control, inoculation with Nitroxin, inoculation with Barvar 2 and inoculation with both bio-fertilizer). The use of chemical and biological fertilizers in the maternal plant had a positive and significant effect on germination and seedlings growth of artichoke. The results showed that among different levels of chemical fertilizer, the highest 1000 seed weight, germination percent, germination rate, vigor Index, plumule dry weight, radicle dry weight, seedling dry weight, radicle length, plumule length, seedling length was obtained in the residual effects of 100% chemical fertilizer + 100 kg nitrogen per hectare. Seed inoculation with both bio-fertilizer had the maximum amount of mentioned attributes. The control level had the highest mean of germination time. It councluded that application of chemical fertilizers along with biological fertilizers can lead to improvement of most germination indices in artichoke plants by increasing the absorption of nutrients such as nitrogen and phosphorus.
