WebFeb 1, 1980 · Abstract. During grain formation stage (90 to 110 days), the youngest flag leaf of rice (Oryza sativa L. cv. Jaya) remained metabolically most active (as indicated by cellular constituents and enzyme activities) and the third leaf the least active.At the grain development stage (110 to 120 days) the above pattern of age-related senescence of the … WebThe top three leaves especially flag leaf contributes most to grain yield [20, 13]. Greater [13] and larger leaf area index (LAI) during the grain filling period. Flag leaf has an important role in rice yield by increasing grain weight in amount of 41 to 43 percent. For this case flag leaf is activist leaf at grain filling period.
WebAug 13, 2015 · THE leaf of grasses typically consists of a relatively narrow blade and sheath enclosing the stem, and venation is parallel in the blade and the sheath ().Because large leaves intercept more light, the leaf area of the blade strongly affects final yield in cereal crops (Watson 1952).To produce plants that intercept light efficiently, leaf angle has … WebLouisiana Rice Production Handbook 43 one-leaf stage of growth rice has a primary leaf and a completely developed leaf. All subsequent leaves after the first leaf are complete leaves. The sheath is the bottom-most part of a com-plete leaf. Initially, all leaves appear to originate from a common point.

The other leaves are normal except the flag leaf, which is slightly modified. Leaf size increases with node order on the culm up to the third leaf below the flag leaf. Most of the early to medium-duration rice cultivars produce 10–18 leaves on the main shoot.
WebApr 3, 2024 · This is because the rice flag leaf is the main organ for the photosynthesis, therefore water deficiency will lead to the curl of the rice flag leaves and affect the opening and closing of the stomata and the synthesis of chlorophyll, so that the ear cannot grow normally [16,17].
