| ABSTRACTThe castor bean crop plays an important social, environmental and economic role, especially due to possibility of its use as feedstock for the generation of clean energy. Thus, this study aimed to evaluate the contents of photosynthetic pigments, cell membrane extrusion and the relative water content in the leaves of the castor bean cultivar ‘BRS Energia’ under silicon and salinity levels. The experiment was carried out at Embrapa Cotton, in a completely randomized design, in a 4 x 4 factorial scheme, and the treatments consisted of four silicon levels (0, 100, 200 and 300 mg L-1) and four water salinity levels of (ECw 0, 2, 4 and 6 dS m-1), with three replicates. The gradual increase in salinity levels reduced the concentration of photosynthetic... |

| The experimental study design was used to examine the effects of accelerated aging on deterioration of seed quality and electrolyte leakage of cucumber seeds. The original cucumber seeds had 99 germination percentage. The cucumber seeds were taken to accelerated aging process; in aging chamber with constant temperature 450C and 100% of relative humidity for 0-21 days. The seeds were taken every three days for 3, 6, 9, 12, 15, 18, and 21 days and tested of seed quality. After that, the seeds were divided into 2 lots. The first lot was examined for conductivity values and measured K+, Ca2+, Na+, and Mg2+ leakage. The second lot was examined seed quality under laboratory and green-house conditions. Additionally, The results were shown that after 6th days of... |
