        In the autumn of 2013， leaves of greenhouse-grown tomato plants showed symptoms of interveinal
  chlorosis， and together with stunted， marginal curling and crumpling. As the disease progressed， leaves become
  thick and crisp， similar to symptoms induced by Tomato chlorosis virus（ ToCV） and Tomato yellow leaf curl
  virus（ TYLCV） were collected from greenhouse-grown tomato plants in Shouguang， Shandong Province. The
  specific primer pairs of CP-F/CP-R specific to ToCV and TY1-R/TY1-F，TY2-R/TY2-F，TY3-R/TY3-F
  specific to TYLCV were used to detect ToCV and TYLCV， respectively. 774 bp（ GenBank accession number：
  KC709510） and 2 781 bp（ GenBank accession number： KJ546418） specific fragments were amplified from the
  same symptomatic samples. Sequence analysis of the amplified sequence of KC709510 showed 99.6% nucleotide
  sequence identity with ToCV-BJ（ KC311375） isolates and the sequence of KJ546418 showed 99.6% nucleotide
  sequence identity with TYLCV-SDWF-L7（ KC999850） isolates registered in the GenBank.

  To clarify the characteristics and inheritance of cabbage（Brassica oleracea L. var. capitata L.）
  glossy wax-less mutant LD10，the major agronomic characteristics and nutrient contents of LD10 were tested，
  and ultra-structures of leaves in mutant material LD10 and normal material 21-3 were measured，observed
  and comparatively analyzed. LD10 and 21-3 were taken as parent to construct 6 generations population，and
  inheritance analysis onthe glossy wax-less characteristics of LD10 was conducted. The results showed that there
  was little wax on the leaves of LD10，while the wax on the leaves of 21-3 was abundent，and the granular wax in
  LD10 was of long stick shape，significantly different from the wax in 21-3. The glossy wax-less trait in cabbage
  LD10 was controlled by one single recessive gene named cgl-4. One molecular marker（LT-SSR16）linked to
  cgl-4 with genetic distances 4.7 cM. Another F₁ population obtained through crossing LD10 and 10Q-961 showed
  that the genes leading to glossy wax-less trait were at different locations in the two glossy wax-less materials.

  Tomato（ Solanum lycopersicum L.）micro-TOM is a model organism for biology study. Its regeneration
  system in vitro is of vital importance for genetic transformation and developmental biology study. But tomato micro-TOM
  tissue culture is not only time-consuming and tedious， but also frequently polluted by microorganism. This experiment
  introduces a new method of regeneration system in vivo by removing axillary and apical buds of tomato. The method has
  high speed and efficiency， and does not rely on exogenous hormone. It has layed a foundation for simplifying tomato
  genetic transformation and provided a good material for plant regeneration mechanism study.

  The study about planting Flammulina velutipes was conducted by taking Chinese prickly ash
  branch as raw material．The result showed that the formulation with 45% Chinese prickly ash branch was suitable for Flammulina velutipes cultivation. The average yield and biologic efficiency of Flammulina velutipes fruiting\
  body planted with Chinese prickly ash branch as the main raw material was slightly lower than that planted with the
  cottonseed hulls as the main raw material．But Ca and Fe contents were significantly higher in the fruiting body
  grown on Chinese prickly ash branch than that grown on cottonseed hulls．There were no significant differences in
  the contents of Mg，Cu，Zn， protein， fiber，ash and sugar contents of the fruiting body grown between Chinese
  prickly ash branch and cottonseed hulls．For the total amino acids contents and essential amino acids，the fruiting
  body planted with Chinese prickly ash branch were richer than that planted with cottonseed hulls．Chinese prickly
  ash branch may be used as raw material for planting Flammulina velutipes，which was proved to reduce the
  production cost and improve the ratio of input and output．

  Micro-climate observation and vegetable field experiment were carried out during 2009-2013
  in mountains areas of Southwest Hubei at different altitudes. Spatial and temporal variation characteristics of
  meteorological elements such as temperature， precipitation， evaporation was analyzed. The correlation of yield，
  quality of pepper， lettuce， and other vegetables， and meteorological conditions were also analyzed. The result
  showed that in the sustain duration with ≥ 5 ℃、≥ 10 ℃、≥ 15 ℃ the decreasing rate with height increasing
  per 100 m were 4.8 days，5.5 days，6.8 days，respectively. The precipitation and humidity index increased
  with height increasing. The fruit setting number of single pepper plant（thermophilic vegetable）and per unit
  area yield both have significant relation with the duration of days ≥ 15℃ in the flowering and fruiting stage. The
  contributions of each additional day to single plant fruit setting number and yield per unit were 0.32 and 1.10 t·hm^-2，
  respectively. The most suitable planting conditions for warm season vegetables were height between 800-1 200 m，
  temperature ≥ 15 ℃， sustaining for 100-130 days. There was no summer above 1 600 m hight，where was the
  suitable planting area for hardy vegetables.

  Taking soil for 5 years continnous cucumber cropping as material and utilizing pot culture method，
  this experiment adopted 4 treatments： no soybean straw returning to the field（CK）； inoculation rhizobium
  soybean straw returning to the field（T1）； inoculation rhizobium soybean straw with no root nodule returning to
  the field（T2）； no inoculation rhizobium soybean straw returning to the field（T3），and studied the effect of
  these treatments on soil sucrase activity and microbe quantity under different field moisture capacity. The results
  showed that the fungi quantity in T1 was significantly lower than CK in 25％、50％ field moisture capacity for 50
  to 140 days，and bacterial quantity maintained a high level in prophase of cultivation（＜ 50 days）. Under 75％
  field moisture capacity，actinomyces quantity of the returning treatments was significantly higher than the control.
  In a word，25％，50％ field moisture capacity could make the bacterial quantity maintaining a high level，and
  reducing fungus quantity，the returning treatments were better than no returning treatments，inoculation rhizobium
  treatments were better than no inoculation rhizobium treatments. The actinomyces quantity maintained a high level
  under 75％ field moisture capacity in late culture stage（＞ 110 days）.
