本研究选用不同小麦品种，采用盆栽试验，通过水分胁迫处理以及剪叶、包穗、包茎处理，研究了水分亏缺下不同器官光合产物对籽粒产量的贡献以及穗轴显微结构的变化，测定了水分亏缺下小麦不同生育期叶片保护酶活性、蔗糖磷酸合成酶的活性以及光合特性等生理指标。

The results show that not only the growth of C. wenyujin in lime soil is possible, but also the biomass, yield of medicinal part, the content of oil from the tuber and its medicinal components are higher than those from red soil. The C. wenyujin from lime soil quickly assumes etiolation during initial growth period. Surprisingly, the lusty leafs of C. wenyujin planted in red soil turn to pale and brown flecks occur in the leafs with the fertilization of N, P, K. It is concluded that C. wenyujin can be planted in lime soil; C.

结果表明：温郁金不但可以在石灰土上生长，而且其药用部位的产量、莪术油的含量及莪术油中主要药用组分β-榄香稀等的含量都较大；石灰土上生长的温郁金在生长前期较快地表现出老叶明显发黄的缺肥症状，而红壤植株在追加N、P、K 3种大量元素后功能叶子呈现黄白色，且夹带有褐色斑点的缺肥症状；石灰土中Fe元素有效态含量比红壤低一个数量级，但在石灰土上种植的温郁金植株其Fe元素含量并不比红壤上的低。

Compare to the other 2 treatments, the weight of root in wormcast is 1.49 times as in cow dung, 2.63 times as in soil;4. Compare to other treatments, earthworm breed in the hole which fertilizing cow dung can increase the leaves nutrient content of ber significantly, and correct the grass tetany;5. Earthworm breeds in the hole which fertilizing cow dung can improve the yield of ber and fruit quality.

And the leaf succulence of Salsola implicata and Suaeda linifolia changes drastically, strong drought resistance is indicated, but that of Halocnemum strobilaceum and Kalidium foliatum is not

后期：亚麻叶碱蓬和密枝猪毛菜叶表面腺毛、密枝猪毛菜盐腺、盐节木乳突状突起明显；密枝猪毛菜盐囊泡有或缺；密枝猪毛菜和亚麻叶碱蓬粘液细胞出现；盐节木和盐爪爪贮水组织和异常维管束发达；除盐节木外，其他三种植物叶肉质化加强；这四种植物气孔下陷，栅栏组织变薄，但排列更紧密。

H+ efflux and Fe3+ reduced substances release by the roots were inhibited by removing chlorotic leaves and buds caused by Fe deficiency, and progressively increased as they sprouted again.

摘除缺铁失绿的新叶和顶芽，抑制根系分泌H+和Fe3+还原物；但随着新叶的重新长出，根系分泌H+和Fe3+还原物的速率逐渐提高。

A one-step method for the synthesis of aromatic indolizine derivatives byintramolecular 1,5-dipolar cyclization reaction of 2-(2-arylethenyl)pyridinium N-ylidesin the presence of an oxidant has been studied for the first time. In the presence ofelectron-deficient olefins, however, 2-(2-phenylethenyl)pyridinium N-ylides underwent1,3-dipolar cycloadditions and then aromatized in situ by TPCD to produce indolizinederivatives, indicating 1,3-dipolar cycloaddition proceed more readily than 1 ,5-dipolarcyclization in these conditions. Pyridinium disubstituted N-ylides, readily obtainedfrom corresponding pridinium and β-chlorovinyl ketone, underwent thermalintramolecular 1,5-dipolar cyclization to give indolizine derivatives easily.Indolizinecarbaldehyde derivatives were synthesized starting from 2-pyridinecarbaldehyde in four-steps involving 1,3-dipolar cycloaddition reaction.

本文首次研究了2-(2-芳基乙烯基)吡啶N-叶立德在氧化剂存在下的分子内1，5-偶极环化反应，采用一锅法合成了中氮茚衍生物；研究了这些N-叶立德的1，5-偶极环化和1，3-偶极环加成反应的选择性，发现当有缺电子烯烃存在时，优先进行1，3-偶极环加成反应，而不再发生分子内1，5-偶极环化反应；由β-氯乙烯酮方便地得到了烯丙基N-叶立德，他们在加热时进行分子内1，5-偶极环化反应而得到中氮茚衍生物；由2-吡啶甲醛为起始原料，通过1，3-偶极环加成反应等四步反应，得到了重要的中氮茚甲醛衍生物，这些反应都具有条件温和和操作简便的特点，是合成中氮茚衍生物的新方法。

Under P-deficiency stress, IAA concentration in asparagus bean plant increased, and IAA translocated from shoot to root, then IAA concentration in root increased, and the ratio of IAA concentration in root/that in young stem and leaf increased, then the ratio of root/shoot increased, due to more carbohydrate translocated to root.

缺磷胁迫下长豇豆幼苗IAA浓度升高，并从地上部向根系运转，使根系IAA浓度和根系IAA含量/嫩茎叶IAA含量的比值升高，增强了碳水化合物向根分配的力度，促进了根冠比的提高，对缺磷敏感的二芦白升高最大，因而根冠比也升高最大。
