| Abstract | ||||
| A field experiments were carried out in season of 2016/2017 at Botanical garden, Botany and Microbiology Department, Faculty of Science, Al- Azhar University, Nasr City, Cairo, to study the role of bio stimulant (seaweed and plant leaves extracts as a liquid fertilizer) and some growth regulators (indole acetic acid and benzyl adenine) as comparative studies to select the better for improving the growth, biochemical constituents and yield of sesame plants. The results revealed that application leaves extracts of Punica granatum showed significant improvement effects on shoot length, number of pods/plant, weight of seeds / plant, contents of chlorophyll a; b; total chlorophyll (a+ b), carotenoids, total lipids, amylases and peroxidase activities of sesame plants as compared to the other treatments. Fresh and dry weight of shoot was significant increases by using Olea europaea leave and Sargassum latifolium water extracts. Carotenoids content was significant increase in response to all of bio stimulant growth regulators. Olea europaea, Carolina elongata leaves water extracts (5g/L) and benzyl adenine (50 ppm) caused significant decrease of chlorophyll a, b and a+b. Total soluble carbohydrates of shoots of sesame plants significantly decreased in response to Psidium guajava leaves extract compared to the control and other treatments. However, Olea europaea and benzyl adenine caused significant increase in total soluble carbohydrates at yield stage. All treatments caused significant increase of total lipids of sesame plants. Data cleared that, amylase and peroxidase activities significantly increased by all treatments. | ||||
