The microstruc-ture of normal and vitrified shoots and the characteristics of their stomas on leaf surface were compared by paraffin section and leaf epidermis-tearing method. The results showed the palisade tissue of Aronia melanocarpa El oit consists of 2-3 lay-ers of cells. The stomas on lower epidermis cave in, and are smal and dense. There are abundant vessels and sieve tubes in stems. ln contrast, the main veins of vitrified shoots are unobvious, messy and irregular. The boundary between pal-isade tissue and spongy tissue is not obvious. The stomas open circularly and bigly. The stems are swel ing and thick, but the pith parenchyma cells are broken.展开更多

The potential energy has been calculated over a wide range of internuclear separation for the 21 low-lying electronic states of the LiCl molecule dissociating into Li (^2S, ^2p, ^3S)+Cl (^2p). The (4)^1∑^+, (3)∏, 1-3^3∑^+, 1-3^3∏, 1,3Δ, ^1,3∑^-, (5)^1∑^+,(4)^3∑^+, (4)^3∏, (4)^3∏ excited states are studied for the first time in theory. Molecular spectroscopic constants .(Re, De,ωe, ωeΧe,Be and αe) have been derived for the 9 bound states (X^1∑^+, (3)^1∑^+, (2)^3∑^+, ^1,3Δ, ^1,3∑^-, (4)^∏, (4)^3∏) with a regular shape, and the spectroscopic constants of ground states X^1 ∑^+ are in good agreement with available experimental and theoretical values. The relative differences between experimental values and our values for Re, De, ωe, ωeΧe, Be and α3 are 1.02%, 0.60%, 1.72%, 9.46%, 2.0%, and 0.75%, respectively. Moreover, vibrational levels of 9 bound states, which have not been investigated experimentally, are computed.展开更多
