Leaf number of sorghum stalks
1936
Sieglinger, J.B.
The total number of leaves on the main stalk, including those formed during the seedling stage, averaged 16 to 27 leaves per stalk, in 21 sorghum varieties. There was a range of 5 to 10 leaves in the number on individual stalks within a variety, even when grown from selfed seed. Both season and date of planting influenced the number of leaves of a given variety. The number of leaves and length of vegetative period were highly correlated; a correlation coefficient of 0.853 +/- 0.029 having been obtained. The period between emergence and heading averaged 2.8 to 3.5 days per leaf for different varieties. The number of leaves, or nodes, also is closely related to size of leaf, forage yield, diameter of stem, vigor, and height of stalk. Early maturing sorghums have few leaves and consequently are limited in production.
