The Comparison of Branch and Leaf Joining Force for Two Plants

Abstract:

Using the method of resisting vertical force for leaf, the leaves of Caragana microphylla Lam and Hippophae rhamnoides Linn were conducted to test the branch and leaf joining force. The results show that two plants leaves fracture in petiole, when they resist the vertical force, the branch and leaf joining force of the Caragana microphylla is greater than that of Hippophae rhamnoides, and ranges of joining force are 0.92-5.20N and 0.28-1.18N, respectively. The correlation is not obvious between the joining force and branch diameter of the leaf growth and petiole diameter for the two plants, and the correlation coefficient of Caragana microphylla is -0.1965 and 0.1418, respectively, the correlation coefficient of Hippophae rhamnoides is -0.0235 and 0.2655, respectively. But with Caragana microphylla rachis diameter increase, the joining force of its leaflet has a raising tendency. When the two shrubs are eroded by wind, compared with Hippophae rhamnoides, the leaves of Caragana microphylla are not easy to be blown off, that is give full play to the wind-break potency of shelter belt, so Caragana microphylla is the optimal wind-break plant.
