Abstract

In order to evaluate the EARLY VIGOUR (early season dry matter accumulation) of cotton (Gossypium hirsutum L.) seedlings, two field and laboratory studies were conducted in 2001 cropping season. In this research, 12 cultivars with determinate (Oultan, No-228 and Lamberaite), semi- determinate (Shirpine, Shirpine 603 and Shirpine 533) and indeterminate growth habits with normal leaf shape (Deltapine 50, Zeta 2 and 1097) and Okra leaf shapes (Red leaf Okra, Super Okra and Okra) were studied in a randomized complete block design with 4 replications. Cultivars with the greater seedling dry matter in the field experiment (44 days after planting) was selected and some of their morphological and physiological characteristics were evaluated in both field and laboratory studies. These selected cultivars were Oultan (from the determinate cultivars), Shirpine 603 (from the semi-determinate cultivars), Deltapine 50 (from the indeterminate cultivars with normal leaf shape) and red leaf Okra (from the indeterminate cultivars with Okra leaf shape). The results of the field study showed that red leaf Okra and Shirpine 603 had the highest and lowest dry matter, hence early vigor, respectively (P<%5). Although there were no significant differences between Leaf Area Index (LAI) of Oultan and red leaf Okra, the Crop Growth Rate (CGR) of red leaf Okra was the greatest among all four cultivars; it had also the highest Net Assimilation Rate (NAR). Deltapine 50 had the highest mean of Leaf Area Ratio (LAR) and Leaf Weight Ratio (LWR) but it could not produce high dry matter, because its LAI and NAR were low. The results of the laboratory study showed that red leaf Okra could produce the highest seedling dry matter at twelve days after sowing in incubator and had the greatest seed reserve utilization efficiency and GERMINATION capacity (P<%5). The highest correlation coefficient was observed between dry matter production with maximum Relative Growth Rate (r= 0.99**) in the field and with coleoptile dry matter (r= 0.99**) in the laboratory.
