Study on Pollination Compatibility of Superior Lonicera caerulea Individuals

In order to solve the problems including low fruit-bearing rate and low yield caused by blind plantation in production, the medium formula for pollen germination of Lonicera caerulea L. var. edulis Turcz. ex Herd., its pollination habit, self-compatibility and open pollination compatibility between different superior individuals were investigated with superior individuals from superior wild individuals of L. caerulea in Changbai Mountains as experimental materials. Self-compatibility and open pollination compatibility among different fine plants provide theoretical basis for its further application and further selection of new varieties. The results showed the optimal medium for germination of L. caerulea pollen was 27.5% sucrose ＋ 100 PPM boric acid with a pH value of 6.0. On this medium, the superior individuals L1, L2 and L3 had the pollen germination rates of 53.4%, 50.9% and 51.6%, respectively. The three superior individuals had no significant differences in the quantity of germinated pollen tubes, which ranged from 1 to 4. The three excellent single plants were the most likely to germinate a single pollen tube, accounting for 83.3% of the pollen germinated and 89.6% of the pollen germinated. Therefore, in production, it is necessary to plant L1 with a certain amount of pollination trees or plant it together with multiple species, to improve its yield. On the contrary, L2 and L3 have no need for pollination trees theoretically, but whether the fruits obtained by self-pollination and outcrossing differ in quality still needs further study.

Nutritional components in dry fruits of Lonicera caerulea L.var.edulis Turcz.ex Herd.collected from Hulun Buir of Inner Mongolia have been analysed.The results show that dry fruits mainly contain sugar(243.40 mg·g-1),crude protein(87.49 mg·g-1),crude fat(86.30 mg·g-1),VB2(0.543 mg·g-1),VPP(2.809 mg·g-1),VA(4.66×10-3 mg·g-1),VE(3.188 mg·g-1),carotene(1.661 mg·g-1),essential microelements(0.852 mg·g-1) including Fe,Mn,Zn,Cu,Se and essential amino acids(22.97 mg·g-1).It also contains VC,VB1,K,Na,Ca,Mg,P and other nonessential amino acids.

接骨木复合饮料的研究（Ⅰ）──蓝靛果忍冬果实的食用价值研究

药用植物蓝靛果忍冬是接骨木复合饮料的主要成分之一，它的成熟果实不仅是清热解毒的天然药，而且是味道鲜美的果品；研究确定了蓝靛果忍冬成熟果实的果汁加工工艺，并对所得果汁进行了较全面的分析。测出了果汁中含有缬氨酸、亮氨酸、赖氨酸等１８种氨基酸，维生素Ｃ，维生素Ｂ＿１，维生素Ｂ＿２，以及Ｋ、Ｃａ、Ｍｇ、Ｆｅ、Ｚｎ等１４种微量元素。对蓝靛果的食用价值进行了综合评价，并对合理开发这一有用资源提出了建议。

伊春地区宽叶蓝靛果人工栽培试验

在伊春地区进行宽叶蓝靛果人工栽培试验的结果表明,宽叶蓝靛果扦插苗对该地区自然因子适应性较好,造林当年苗木生长高峰出现在8月中旬,第二年生长高峰提前至6月中下旬。造林密度对宽叶蓝靛果苗木生长有一定影响,适合的造林密度能促进苗木生长,以1 m×1.5 m的密度较为适宜。

蓝靛果忍冬天然色素提取及稳定性的研究

采用溶剂提取法,对蓝靛果忍冬天然色素的提取进行研究,并对影响其稳定性的因素进行了分析。以乙醇浓度、提取温度、提取时间、提取pH值为研究对象进行单因素试验和正交试验,同时研究光照、蔗糖、氧化还原剂、金属离子对色素稳定性的影响。结果表明:最佳提取工艺条件是乙醇浓度60%,60℃,60min,pH值2。随着蔗糖量的增加,吸光度也逐渐增加,色素对氧化还原剂稳定性较差,金属离子Fe3+、Ca2+、Cu2+对色素的影响较为稳定,Na+对色素的影响比较显著。
