The Effects of Temperature and Water on the Seed Germination<\/span><\/a>

Abstract:<\/span><\/p>\n

The seed germination and seedling growth of rapeseed are crucial stages in plant life,<\/span>
especially when facing abiotic stresses. In the present work, the effects of water and temperature on<\/span>
seed germination and seedling growth were investigated in a rapeseed crop (<\/span>Brassica napus<\/span> L.). The<\/span>
plants were examined under different temperature levels (5<\/span> \u25e6<\/span>C, 10<\/span> \u25e6<\/span>C, 15<\/span> \u25e6<\/span>C, 20<\/span> \u25e6<\/span>C, 25<\/span> \u25e6<\/span>C, 30<\/span> \u25e6<\/span>C, and<\/span>
35<\/span> \u25e6<\/span>C) and water levels (twenty-nine levels based on either one-milliliter intervals or as a percentage<\/span>
of the thousand-kernel weight (TKW)). Moreover, planting densities and antifungal application<\/span>
techniques were investigated in the study. The findings demonstrated substantial variations between<\/span>
all the growth parameters investigated at all the tested temperatures, and 20<\/span> \u25e6<\/span>C was considered the<\/span>
optimum within a broad range of 15\u201325<\/span> \u25e6<\/span>C. Water availability plays a significant role in germination,<\/span>
which can be initiated at 0.65 mL, corresponding to 500% of the TKW. The method of TKW is a<\/span>
more accurate aspect of water application because of the consideration of the seed weight and size.<\/span>
The optimal water range for the accumulation of dry weight, 3.85\u20135.9 mL (2900\u20134400% of TKW),<\/span>
was greater than that required for seedling growth, 1.45\u20133.05 mL (1100\u20132300% of TKW). Twenty to<\/span>
twenty-five seeds per 9 cm Petri dish exhibited the most outstanding values compared to the others,<\/span>
which provides an advantage in breeding programs, especially when there are seed limitations. Seed<\/span>
priming is a more effective antifungal application strategy. These data can be incorporated into future<\/span>
rapeseed germination in vitro studies, breeding programs, and sowing date predictions<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
