16 Studies on Physiological Response of Watercress to Cd Stress and Its Cd Accumulation
HAN Cheng-Hua, ZHOU Zeng-Hui, ZHANG Na, JIANG Jie-Zeng
A hydroponic experiment was carried out to study the effects of Cd on the growth of watercress（
Nasturtium officinale R. Br.）．The indexes under treatments of different Cd concentration，
such as agronomic characters，yield，root activity，net photosynthetic rate（ Pn），antioxidant enzyme
activity and the concentration of malondialdehyde（ MDA），phytochelatins（ PCs） and Cd contents
changes at different parts of watercress were studied. The results showed that low Cd concentration would
influence watercress growth，i.e. the accumulation of MDA would rise，while high Cd concentration
would lead to the decline of root activity and Pn．Antioxidases and PCs played a cooperative role in alleviating
Cd toxicity. But the alleviation was dominated by PCs chelation under the condition of low Cd
concentration，while it would be dominated by the antioxygenation of SOD，POD，CAT along with the
increase of Cd concentration. Cd is easily accumulated in watercress．The Cd concentration in edible
parts of watercress had exceeded the limit value of national standards，when the concentration of Cd in
the nutrient solution reached 0.20 mg·L-1．In conclusion，watercress is a vegetable of Cd-sensitive
type，more attentions should be paid on Cd pollution during its production.

22 Effects of Storage Environment and Maturity on Quality of Mini Wax Gourd
FANG Yu-Peng, WANG Li-Ping
Taking mini wax gourd（ Benincasa hispida Cogn. var. chieh-qua How.）‘Chunfeng’as
experimental material，the paper studied the influence of different harvest maturity and storage environment
on the quality and storability of mini wax gourd. The results indicate that although the low harvest
maturity fruit has high nutritional value，it is not tolerant to storage. Its fruits got shrank after 3 days
storage．The high harvest maturity fruit is tolerant to storage，and can still maintain good appearance
after 100 days．Besides，storage under basement environment could delay the quality changed．Fruits
of all maturity got rotten after 20 days under cold storage condition．The results showed that，for short
period of storage，it is better to choose the low harvest maturity fruit picked 15 days after flowering；
while for long period of storage，the high harvest maturity fruit picked 30-45 days after flowering was
chosen to store under relatively lower temperature in basement environment.

27 Effects of Different Storage Factors on Pollen Viability of Watermelon Variety
‘Zaojia’
LIN Yi, YANG Yu-Bin, WANG Chi, YANG Jing-Hua, ZHANG Ming-Fang
The paper studied watermelon〔Citrullus lanatus（Thunb.）Matsum. et Nakai〕pollen
cryopreservation methods and pollination technique．The result indicated that pollens of‘ Zaojia’ watermelon
can be stored at -18 ℃ or -25 ℃ under vacuum condition for 186 to 223 days with over 50% activity.
Pollen activity can be varied under different storage conditions，of which -25 ℃ can have longer
storage time than -18 ℃，and the pollen vitality is higher．The stored pollens should be activated at 25
℃ for 30 min before usage，so as to achieve higher fruit setting rate．The application of stored pollen
will not influence the quality of watermelon.

Garlic Growth and Yield
LIU Tong-Jin, CHENG Zhi-Hui, MENG Huan-Wen, Sikandar Hayat, ZHAO Hui-Ling
In order to understand the differences in garlic（Allium sativum L.） growth and yield
in substrate plastic tunnel between under single and intercropping conditions，the paper set up 3
cultivation treatments of tomato monoculture，tomato/garlic intercropping and garlic monoculture to test
garlic mass growth，yield，and substrate physicochemical properties．The results indicated that the
morphological index of intercropped garlic bulb was significantly lower than that of garlic monoculture，
but the ratio and yield of single-clove bulb was significantly increased．The land equivalent ratio of
tomato/garlic intercropping was high as 1.56 with obvious advantages．The single-clove bulb ratio of
intercropped garlic was 58.1%. Available nitrogen，phosphorus and potassium contents were high both
in monoculture and intercropping substrate．There were no significant differences observed in sucrase，
urease activity，bacteria and actinomycetes number．The major limitation for intercropped garlic growth
was light.

37 Characteristics of Ammonia Volatilization of Special Slow-release Fertilizer
and Effects of Slow-release Fertilizers on Eggplant Quality and Yield
ZHANG Ming-Zhong, HAN Gui-Qi, XU Wei-Hong, LIU Jun, WANG Chong-Li, YANG Yun, ZHANG Jin-Zhong, WANG Zheng-Yin, XIE De-Ti
The experiment of‘ venting method’ in laboratory and pot experiments were carried out
to investigate the characteristics of ammonia volatilization of special slow-release fertilizer in soil，and
its effect of special slow-release fertilizer on yield and quality of eggplant（Solanum melongena L.），
uptake of N，P and K，fertilizer use efficiency．The results showed that the special slow-release fertilizer（
QSRF） for vegetables could significantly reduce the volatilization rate of ammonia and accumulation
of ammonia volatilization in the experiment of‘venting method’in laboratory．At the beginning of
laboratory experiments，the highest average rate of ammonia volatilization was observed in large particle
urea（PUR）treatment．However，28 days later，the volatilization rate of special fertilizer（QCCF）
was the highest．Accumulations of ammonia apparent volatilization by QSRF had reduced by 62.17%
and 56.76%，compared with PUR and QCCF．Obviously in pot experiment，QSRF significantly improved eggplant yield. Yield of the 2 eggplant varieties under QSRF treatment had increased by 37.1%
and 37.8% than under the common compound fertilizer（ OCCF），and increased by 1.4% and 27.6%
than the commercial slow-release fertilizer（ MSRF）．Contents of VC and amino acid in fruit were increased
by QSRF treatment. Content of nitrate was evidently lower than that treated by OCCF．The apparent
fertilizer utilization rate of N and K was increased by QSRF treatment，while no obviously effect
was found on apparent fertilizer utilization rate of P.
