The second subcluster contained ‘half variegated’ lamina, ‘vertical stripped’ lamina and ‘malformed’ plant . In addition to petiole width, the following characters may be useful to identify certain cultivars or cultivar groups: petiole length (in relation to leaf blade), petiole pubescence, shape of the petiole wing apex (e.g., rounded or obtuse vs. emarginate), degree of overlap of petiole wing apex and the supertending leaflet. The variant ‘spear shape lamina’ was separated in between the … As nouns the difference between leaf and blade is that leaf is the usually green and flat organ that represents the most prominent feature of most vegetative plants while blade is the sharp cutting edge of a knife, chisel, or other tool, a razor blade. The results of phylogenetic comparative analyses Find more information on differences between Simple and Compound leaves. The lamina possesses a network of veins. Second, the petiole is not circular but U‐shaped in cross‐section with the channel on the upper surface and the lamina emerging from the upper arms of the U. 4. Significant allometric scaling relationships were found between petiole mass and lamina mass, and between petiole mass and lamina area, with common slopes of 0-872 and 0-742, respectively, both significantly departed from the value of 1 -0. The variants ‘winged petiole’ and ‘deformed lamina’ were clustered together along with the normal plant . A typical leaf of Ficus religiosa (pipal) has a broad thin, flat structure called the lamina. Simple Leaf In a simple leaf such as guava, banana, sycamore or mango leaf, the blade is completely undivided. The thin stalk below the lamina is the petiole. - 32706842 2. Petiole needed to be defined more clearly with respect to Chaptalia, thus: petiole The basal portion of the leaf below an abrupt narrowing of the lamina, with a narrow margin nearly parallel to the midvein or slightly expanding toward the base and lacking the undulate margins and mucros typical of the lamina … The compound-leaved species were observed to be significantly greater in both lamina … the ratio of the simulated petiole length ( L ʹ p ) to the actual petiole length ( L p ) as follows: What is the difference between Veins and Lamina in plants? lamina area; whilst a contrasting pattern was observed between lamina mass and petiole mass, in which the evergreens had a greater biomass allocation to lamina for the same petiole mass relative to the deciduous. Summary 1 The allometric scaling relationship between lamina and lamina support has rarely been examined, such that its significance to plant life‐history strategies has not been fully explored and understood so far. The leaf shape may also be […] X is the relative petiole length (RPL), i.e. First, the petiole is not straight, but has a gentle ventral curvature of around 0.3 m −1. The veins have both xylem and phloem elements which are continuous with similar tissues of the stem through those of the petiole. For each leaf, we fixed the sum of lamina dry mass (M a) and petiole dry mass (M p), and altered biomass allocation between the lamina and petiole.
