Experiments on seedlings, which strongly affect productivity, were conducted to obtain cotyledon unfolding time and the time series projected area of cotyledons and true leaves of individual seedlings of romaine lettuce (Lactuca sativa L. var. longifolia), using RGB images. This was also undertaken ...
The first leaves, also called cotyledons, generally start yellowing at the 3-week mark, when the second and third sets of leaves have fully developed. This is normal. However,yellowing of the true leaves is a cause for concernand a sign that your seedlings may be overwatered or need fert...
RECOGNITION OF PARTIALLY OCCLUDED PLANT LEAVES USING A MODIFIED WATERSHED ALGORITHM cotyledons and tomato true leaves improved by a factor of 3 and 2, respectively, after it wasapplied to occluded plant leaves in natural outdoor scenes... WS Lee,DC Slaughter - 《Transactions of the Asae》 被引...
Materials and methods Plant materials Seeds of the L. esculentum cultivar Micro-Tom were purchased from Tomato Growers Supply (Fort Myers, FL, USA). The seedlings were used for agroinoculation when the cotyledons had expanded fully and the true leaves were 3–5 mm long. It generally took 10...
(F) Rosette leaves from 7-week-old plants. Arrowheads point to leaf serrations. Scale bars, 2 cm. Red crosses and circles in the boxplots represent the mean and outliers, respectively. ∗p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001 (Student’s t test [for B and E] or...
A simple and efficient method was established for isolating protoplasts from rapeseed cotyledons and leaves, and found that cotyledons might be better than true leaves. Transient expression analysis showed that yellow fluorescent protein (YFP) and luciferase (LUC) could be expressed in rapeseed ...

Development of characteristics of the C[SUB4] syndrome was studied in cotyledons and leaves of NADP-ME type C[SUB4] Salsola richteri, a desert shrub. This species has seeds in which the cotyledons contain chloroplasts, storage proteins, and lipid bodies but no starch. Following imbibition (...
Thus, these two indices seem to be independent of the type of Kranz鈥揳natomy. The presence of atriplicoid type cotyledons in the species with salsoloid structure of true leaves might indicate a close genetic relationship between these two patterns of Kranz-anatomy.doi:10.1023/A:1021972031256...
The early senescent cotyledon (esc1) mutant of Arabidopsis thaliana displays premature senescence of its cotyledons in an acropetal pattern, short stature, a "bushy" rosette, and small, epinastic true leaves. The soluble sugars sucrose, glucose and fructose have variable ameliorative effects on the...
