1971--1984年,曾用不同剂量~(19)Coγ射线,~(60)Coγ+微波14Mev快中于处理苹果品种“富士”及“秀水”的休眠枝。结果表明高注量的快中子处理枝有较高百分数的叉状畸变,而γ射线处理枝出现较多的盲枝。γ射线的重复照射发现较高百分数的形态畸变。1981年在中子注量1×~10(10)中子/厘米~2处理中,发观1-中IV_1-1枝系全红果实的实变系,其着色程度显著优于对照。1982年把该枝系转接后,于1984年获1-中ⅠV_2-1八个枝系,仅采收到2个果实,其着色显著优于对照及当地高接的“长富1”及“长富2”。1981年经果实果皮色素细胞观察发1-1中IV_1-1的果实肩部果皮舍花青素细胞百分数为对照的637.7%;胴部果皮色素细胞为对照的2681%;底部果皮的色素细胞为对照的比数更大。1984年对转接鉴定的1-中IV_2-1果实的果皮色素细胞观察,肩部果皮含花青素细胞百分数为对照的247%,为“长富1”着色系的188%;胴部果皮的色素细胞为CK的262%,为“长富1”着色系的167.9%;底部的果皮色素细胞为CK的251%,为“长富1”着色系的183.3%。 In 1971-1984, dormant branches of apple varieties “Fuji” and “Xiushui” were treated with ~ (19) Coγ-ray and ~ (60) Coγ + microwave 14Mev fast. The results showed that the high fluence of fast neutron treatment branches had a higher percentage of forked distortion, while the γ-ray treatment branches appeared more blind branches. Repeated irradiation of gamma rays revealed a higher percentage of morphological distortions. In 1981, in neutron fluence 1 × ~ 10 (10) neutron / cm ~ 2 treatments, the apparent variability of the whole red fruit of IV_1-1 was highest, and its coloring degree was significantly better than that of the control. After the branch was transferred in 1982, it was obtained in 1984 with 1 branch of Ⅰ-ⅡV_2-1 and only two fruits were harvested. Its coloring was significantly better than that of the control and the local “Long Fu 1” and “ ”Long rich 2“. In 1981, the percentage of pericarp anthocyanidin in Shoulder pericarp of IV_1-1 in fruit 1-1 was 637.7% of that in control, while that in pericarp was 2681% of that in control. The number of pigment cells in pericarp was The ratio of control more. In 1984, the pericarp pigment cells of 1-medium IV_2-1 fruits appraised by the transfer showed that the percentages of anthocyanin-containing cells in the shoulder pericarp were 247% of the control and 188% of the ”Changfu 1" Of the pigmented cells were 262% of CK, 167.9% of the CKD1 color line, and the bottom of the pigmented pigment cells was 251% of the CK and 183.3% of the CKD1.

与友人们吃饭,席间有位孕妇,怀孕27周。知道我是营养师后,她轻描淡写地告诉我,自己两个多月前被检查出贫血,刚刚又检查出血红蛋白仍低(贫血)。我一问才知,她在这两个月内根本没采取任何措施,没把贫血当回事。  即使孕妇没有头晕眼花的贫血症状,缺铁性贫血仍然会严重损害胎儿发育,尤其是大脑的发育,造成宝宝智力低下——未必一定是呆瓜,但后来肯定学习成绩不好。这其中的道理是非常简单的:   血液负责给全身(包
