In order to study the role of fruit tree rootstocks on nutrient content in leaves of two Iranian red flesh apple genotypes and to determine the correlation of nutrients with different secondary metabolites, this study was conducted in Research Garden of Horticultural Sciences of Ferdowsi University of Mashhad during 2017-2019. The rootstocks that used were two dwarfing rootstocks, M9 and B9 and one red flesh apple colony rootstock of Bekran which were tested in a factorial randomized complete block design. The results of this study showed that the rootstock had a significant effect on nitrogen and phosphorus content in leaf samples of two red flesh apple genotypes and Red delicious cultivar, also, rootstock, scion and their interaction had a significant effect on potassium, iron, calcium and zinc content of leaf samples. The effect of B9 on the amount of all elements of scion leaves was negative and the effect of M9 was positive in all cases. The results showed that PAL enzyme activity was positively correlated with nitrogen, potassium, calcium, iron and zinc. Anthocyanin synthesis was also positively correlated with nitrogen content (0.47). The results showed that the amount of potassium, calcium and iron were highly correlated with UFGT activity. Total flavonoid content was also significantly correlated with calcium and zinc (-0.64 and -0.45, respectively) that these effects could be due to the participation of some of these nutrients as cofactors in enzyme activity and or precursors of phenolic compounds and secondary metabolites.

In order to evaluate the effect of different culture media on chemical and quantitative characteristics of Marigold, an experiment was conducted in completely randomized design with eight treatments and three replications in Islamic Azad University of Isfahan (Khorasgan) branch during the year of 2014. The treatments were including garden soil, garden soil + spent mushroom compost, garden soil + spent mushroom compost + rice bran, garden soil + spent mushroom compost + rice bran + manure, garden soil + rice bran, garden soil + rice bran + manure, garden soil + spent mushroom compost + manure, garden soil + manure. The results showed that increasing manure in various treatments enhanced carotenoids and anthocyanin in Marigold, so that the highest carotenoids and anthocyanin was observed in the combined treatment of manure, but adding rice bran and garden soil alone reduced carotenoids and anthocyanin in Marigold. The effect of the combined media (garden soil + spent mushroom compost + rice bran + manure) increased content of leaf flaveonoids, but absent of manure and mushroom compost significantly decreased them. The chemical compositions of Marigold were Delta-Cadinene, Gamma-Cadinene and Phthalic acid. The highest Delta-Cadinene obtained from spent mushroom compost + garden soil + manure medium.

To study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at College of Agriculture, ShahedUniversity in Tehran, 2011. The main plots were allocated to different levels biofertilizer and chemicalfertilizer phosphorus in four levels viz. 1. Control (no fertilizer), 2. Biofertilizer (Nitroxin,biophospherous fertilizer 2), 3. Integrated fertilizer (bio fertilizers+ 50 percent chemical fertilizer), 4.Chemical fertilizer (triple super phosphate). The subplots were allocated to different combinations of 1.Sole alfalfa, 2. Sole fennel, 3. 100 percent alfalfa+ 50 percent fennel, 4. 100 percent alfalfa+ 100 percentfennel. Results showed that the highest amount of crude protein was obtained in alfalfa+ 50 percentfennel at control treatment and the highest dry matter digestibility in sole alfalfa at integrated fertilizingsystem. The lowest percentage of essential oil was obtained in alfalfa+ 50 percent fennel at integratedfertilizing system.
