Two peaks of PAL activity were,observed during callus differentiation of Nico-tiana rustica, Styia rubaudiana (Bartani) Hems and Salvia miltiorrhiza. First peakof enzyme was exhibited both in the differentiated and non-differentiated mediumso that it was not related to cell differentiation, however, it was resulted from theeffeet of transferation to fresh medium (Hahlbroch and Wellman 1973, Kuboi andYamada 1978). The second peak of PAL activity at the late stage (10~12 days)of culture was present only in the...

Two peaks of PAL activity were,observed during callus differentiation of Nico-tiana rustica, Styia rubaudiana (Bartani) Hems and Salvia miltiorrhiza. First peakof enzyme was exhibited both in the differentiated and non-differentiated mediumso that it was not related to cell differentiation, however, it was resulted from theeffeet of transferation to fresh medium (Hahlbroch and Wellman 1973, Kuboi andYamada 1978). The second peak of PAL activity at the late stage (10~12 days)of culture was present only in the differentiated inductive medium indicating thatit could be a marker enzyme for initiating differentiation of callus or suspended cell.The further experiments indicated that the PAL activity was much relatedwith the lignin synthesis and tracheary element (TE) differentiation, and therewas a sequential relation among them. It is in accord with the fundamental rulethat the material metabolizm is always established prior to the morphogenesis

烟草、丹参和甜叶菊愈伤组织在分化过程中一般都出现两个PAL活性高峰。第一高峰在培养第一、二、三天中出现;第二高峰在第十一天前后出现。前者在分化或不分化培养基中都存在,似与组织分化无关,后者只在分化条件下才有,似可作为组织启动分化的指示酶。分化程度不同的组织,PAL活性有很大差异,即将或刚分化的组织活性最高,随着分化的进程活性趋于降低,老化的组织甚至丧失活性。PAL活性、木质素合成和管状份子形成之间有着紧密的相关性。

Foliar treatment of PP_(333) were applied to Chili pear trees to determine its influence on phenolics synthesis and fruit growth.

Under low temperature storage condition, the H2O2 level in the peel of Red Delicious apples increased gradually and reached the highest level in Nov. CAT was more sensitive to low temperature condition than SOD. The SOD,CAT activity and lignin synthesis were higher in the peel of early harvested fruit (EHF)than that in the peel of late harvested fruit (LHF). The CAT activity in the EHF decreased more rapidly than that in the peel of LHF. So that the H2O2 level and superficial scald were higher in EHF than...

在低温贮藏条件下,苹果虎皮病从11一12月间开始发生并迅速加重.在此之前,果皮中H_2O_2水平逐渐上升,11—12月达最大值.H_2O_2水平的变化与细胞中保护系统和木质素合成有关.与晚采果相比,早采果中SOD和CAT活性均高,低温下CAT活性较SOD下降为快,早采果尤为显著,因此果皮中H_2O_2水平也高.抗氧化剂二苯胺对SOD和CAT无影响,但显著抑制木质素合成,降低H_2O_2水平,减少发病率.
