مقایسه‌ رشد، عملکرد و ویژگی‌های ظاهری میوه چهار رقم فلفل‌دلمه‌ای

For comparing the effects of two planting substrates on vegetative growth, flowering rate, fruit appearance and qualities, yield of four bell pepper (Capsicum annum L.) cultivars, a greenhouse 4×2 factorial experiment was done by using a completely randomized design with 4 replications. First factor was 80% cocopeat + 20% perlite and 80% mosspeat + 20% perlite and the second one was four bell pepper cultivars consisted of green Traviata, red Inspratian, orange Aracia, and yellow Taranto. The results showed that mosspeat caused better effects on vegetative growth consist of length and diameter of stem, relative chlorophyll, fresh and dry weight of root and stem and reproductive factors consist of flowering rate, fruit length and diameter, fruit shape index, rigidity and pericarp thickness and it increased fruit number and fresh and dry weight of fruits in each plant in comparison to cocopeat. Amongthe cultivars red cultivar was the superior one for important factors vincluding relative chlorophyll, fresh and dry plant weight, fruit shape index and pericarp thickness. There was significant interaction between cultivar and bed indicating that the response of bell pepper cultivars was varied in different beds
