Chilling Effect on Germination and Seedling Vigour of Some Cultivated Species of Gossypium

Zahid Iqbal Anjum and Asia Khatoon

Abstract: The study was conducted to assess the chilling effect on germination, hypocotyl and root length of two cotton cultivars. Hundred seeds of each Gossypium arboreum A2 genome (G₁) and Gossypium hirsutum AD-1 (G₂) were chilled at 0 °C for 0, 24, 48, 72 and 96 h and then placed in incubator at 32°C. Germination percentage significantly decreased with the increasing chilling period. However, the effect was pronounced on G₁ than G₂. The highest hypocotyl length after 96 h of chilling treatment was 64 mm for G₁ and 91 mm for G₂, under 48 h of chilling treatment. Root lengths of both varieties were maximum under the treatment of 24 h of chilling after 96 h. On the basis of germination percentage, hypocotyl and root length, it may be inferred that G₂ was more cold tolerant variety than G₁.
