The important research results as follows: 1 leaf dissection structure, differences of raspberry and blackberry with drought resistance characteristics must, in 72133.2um between the whole blade thickness. Cross sectional level of epidermal cells were single, small volume, in close together, and all are the cuticle. The upper epidermis thickness in 1124.75um, thickness of epidermal cells in 7.516.5um. Table I were dispersed pores and foreign skin, small table foreign minister or do not behave with many twists and turns. The palisade tissue density, thickness of 36 67.9um, mesophyll tissue with scalelike crystals (in palisade tissue). The main veins contain a significant radial dimension, collateral, the main vein of sumit in two micro pin. 2, under the premise of various types of drought control, have certain infiltration and adhere to turgor pressure conditioning conditioning method but the differences. Russian Red and black, William Te, Bhatti Yum can be accomplished through the process of infiltration conditioning growth bound water content; tulemeen, beautiful features through changing the cell wall elasticity to maintain turgor; Russian Red, William Te, yum, tulemeen in dry clamp under the premise of increasing infiltration of conditioning materials (free proline content) complete infiltration conditioning. The change of free proline of raspberry and blackberry determining drought resistance is a major goal. 3, reduce the level of cell membrane with clamp, six kinds of raspberry and blackberry leaves the permeability increasing gradually, the content of MDA gradually progress, different types of growth or increase the magnitude of the difference. Serious water clamp long, different types of raspberry and blackberry leaf SOD and POD activity were significantly decreased, the two kinds of BlackBerry raspberry varieties decreased more significantly than. In the water control under the premise of high development of raspberry and blackberry affected by different types of high development, affected by the level difference. Light net 4, adequate water supply under the premise of six different kinds of raspberry and blackberry velocity (Pn), transpiration rate (Tr), stomatal conductance (Gs) and water application rate (WUE) has a significant change on discipline. Net light red, black, Russian sumit Bhatti, yum speed change showed a single peak, no "nap" scene, Tuula Ming, William Te at noon 12 when you have obvious "noon break" scene. In the water control condition, the net photosynthetic rate (Pn), the change discipline emerged similar to the premise of full water supply change, just change the scale of absolute cuts, and follow the increase moisture clamped between the net disposal, light velocity (Pn) decreased significantly. The transpiration rate (Tr), stomatal conductance (Gs) and water application rate (WUE) with increasing moisture, clamp sequentially reduced, different kinds of net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs) and water application rate (WUE) in different water reducing rate differences under the premise of clamp. 5, from the two aspects of drought and drought adaptation productivity were evaluated, six kinds of drought resistance in the order: sumit William > > > Russian Red tulemeen > > black at yum. 6, sumit, tulameen, William Te 3 raspberry species in Shaanxi Yangling (0.2cm) emerged from the bud to flowering for 15 to 20 days, in the 13D for your development fastigium. In late 6 to mid July for raspberry and blackberry fruit "WP=6" the concentrated harvest period. Raspberry fruit of flowering to maturity to 27 days, 33 days for blackberry fruit development, the curve was "S" type. 目录: |
