1.The result of mono factor experiment and orthogonal experiment indicated that the o ptimum technology was that the litchi pericarp and 95% ethanol(p H=3) were put in extractor with ratio of 1∶30 (g/mL) to extract for 2 h at 60℃,and the ratio of the pericarp to the solvent and extraction time could have a greater impact on the extraction of antioxidant.
通过单因素实验和正交实验,获得最佳提取工艺条件:按料液比1∶30(g/mL)加入荔枝果皮和95%乙醇(pH=3),在60℃回流2h,提取2次。 对提取效果影响较大的因素是料液比和提取时间。
2.The pericarp and pulp of citrus were separated, After blanching, rinsing and treatment by pectinase, the pericarp were mixed with pulp getting rid of seeds by fatio of 1∶1.4～1∶1.6. Dry and loose pure citrus fruit powder can be prepared by hot air spray drying.
将柑橘(橙)全果皮肉分离,果皮经热烫、水漂及果胶酶适度处理后,与去籽的果肉以1∶1.4~1∶1.6的比例混合,利用热风喷雾干燥方法可获得干燥、疏松的纯天然柑橘(橙)果粉。
3.CAT activity gradually decreased from the pericarp to the core of fruit and POD activity was much higher in the pericarp than that in other parts.
由果皮至果心CAT活性依次降低,而果皮中POD活性极大地高于其他部位。
4.2 The final residue of phoxim in the pericarp was 0.228mg/kg, and which in the pulp and in the core were, 0.0164mk/kg and 0.0111mg/kg after sprayed 1 time and that were 0.0347mg/kg, 0.0313mg/kg, 0.0173mg/kg in the the pericarp, in the pulp and in the core after sprayed 3 times.
2 40%辛硫磷1000倍喷施1次,在鸭梨果皮、果肉、果心中的贱留量分别为0.0228mg/kg、0.0164mg/kg、0.0111mg/kg。 喷施3次,在鸭梨果皮、果肉、果心中的残留量为0.0347mg/kg,0.0313mg/kg、0.0173mg/kg。
5.4) Pericarp thicknesses of isogenetic lines Oh43 (Su,su,sh2) 22 DAP and 26 DAP had significant differences,but there were no differences in pericarp thickness 18 DAP among the three genotypes.
4）分析结果表明，等基因自交系（IsogeneticLines）在不同授粉天数的果皮厚度为18DAP到22DAP增加，22DAP到26DAP有增有减。 此外，果皮厚度在18DAP，3种基因型间无差异，而在22DAP和26DAP3种基因型间有极显著差异。
6.0.2 %H3BO3 spray had significantly increased B content in leaves and fruits,improved N,P,K and Mg accumulation in leaves,descreased Ca content in pericarp,but it did not obviously influenced on Ca content in leaves.
喷施0.2%H3BO3显著提高了叶片和果实组织B水平,促进了叶片和果实对N、P、K、Mg的积累,明显降低了果皮的Ca含量,但对叶片Ca含量无明显影响;
7.The ratio of isocarbophos residual content in pericarp to flesth was 2 times lower than that of parathion-methyl, and the ratio of flesh to core was l~2 times higher.
从果实各部位残留量之比可以看出,水胺硫磷喷易于由果皮渗入果肉,其果皮/果肉含量之比平均低于甲基对硫磷的2倍,而果肉与果心之比高出甲基对硫磷1￣2倍。
8.Putrescine (Put), spermidine (Spd) and spermine (Spm) contents in the pericarp, seed and aril ofHuaizhi litchi (Litchi chinensis Sonn.) were analysed during fruit development.
荔枝果实中多胺含量以亚精胺(Spd)最高,腐胺(Put)其次,精胺(Spm)最低,三者分别于花后7 d和28 d各出现1个高峰。
9.Effects of SO_2 fumigation on the pericarp browning and mass fraction of SO_2 residue in longan fruits
SO_2熏蒸处理对龙眼褐变和SO_2残留质量分数的影响
10.This experiment was made in the University of Illinois at Urbana-Champaign. By measurement of pericarp thickness for 26 inbreds or crosses (genotypes Su, su,sh2 and suse)18,22 and 26 days after pollination (DAP),the results were as follows.
通过对26份玉米材料（基因型为Su，su，sh2，suse）授粉后18d、22d和26d测定果皮厚度，得到4个重要结果；
