Germination Energy, Germination Capacity and Microflora of Allium cepa L. Seeds after RF Plasma Conditioning

Improving germination of Prunus avium L. seeds

To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...

Effect of Parthenium hysterophorus L. on Germination and Elongation of Onion (Allium cepa) and Bean (Phaseolus vulgaris)

Parthenium (Parthenium hysterophorus L.) has become an invasive woody plant in recent times in many part of the world affecting the agricultural productivity. Hence we carried out to evaluate the effect of P. hysterophorus on germination and elongation of Onion (Allium cepa) and Bean (Phaseolus vulgaris). The plant extract prepared by the extractions of 1,2,4,8, and 16 gram powder in a 400ml of...

Maintenance of Pollen Germination Capacity of Vitis Vinifera L. (vitaceae)

Pollen germination of Vitis vinifera L., of the family Vitaceae was examined in fresh and stored pollen upto 48 weeks at different temperature i.e., refrigerator (+4C), freezer (-20C, -30C) and freeze drier (-60C). Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4C and fresh. Freeze dried pollen (-60C) showed the highest germination percent...

Phytochrome and Seed Germination. IV. Action of Light Sources With Different Spectral Energy Distribution on the Germination of Tomato Seeds.

Germination of tomato seeds exposed to a single, saturating irradiation from light sources of different spectral energy distribution seems to be dependent upon the photostationary P(FR)/P(R) ratio established by the irradiation. Germination of tomato seeds exposed to prolonged irradiations from the same light sources does not seem to be controlled solely by the P(FR)/P(R) ratio induced and main...
