introduction lentil (lens culinaris medic) is a member of the leguminosae (fabaceae) family and an important pulse crop grown in iran. growth of lentil plant is highly sensitive to environmental conditions, especially solar radiation, high temperature and water availability. one of the important reasons for unstable lentil yield is the indeterminate growth habit of lentil plants. extensive vege...

Reproductive ecology of Agalinis acuta was investigated by examining potential for self-fertilization before and at anthesis, reproductive output from outcrossed vs. selfed matings, and effects of browsing, plant size, and conspecific plant density on seed and fruit production. These features of a plant species can provide indirect information pertinent to conservation such as patterns and main...

A pot experiment was conducted in a completely randomized design, to study the effect of zinc sulphate (ZnSO4) and Ascorbic acid(AS) foliar application application 20 and 40 ppm was compared to the control (distillated water) on flowering Gazania (Gazania rigens L. daybreak red stripe).Results were analyzed by SPSS software and Duncan test. Results showed that ZnSO<...

to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...

Through competition for pollinators, invasive plants may suppress native flora. Community-level studies provide an integrative assessment of invasion impacts and insights into factors that influence the vulnerability of different native species. We investigated effects of the nonnative herb Lythrum salicaria on pollination of native species in 14 fens of the eastern United States. We compared v...

This study evaluated the effect of artificial pollination on pistachio trees in an orchard at a low ratio of male to female trees in Qazvin province, Iran, over the years 2012-2013. Experimental factors included three female cultivars (Akbari, Owhadi, Kalebozi) and three types of pollinizer (Control, GA, and GB) with three replications. In each female tree, two branches were selected in the nor...
