1 Pollen morphology observation of Pyrus L. in China.

2 This research was carried out to compare protective effects of different packagings(paper-wrap and foam-net packages) on Huanghua pears(Pyrus pyrifolia Nakai cv.

3 Main floral characteristics of Xiangli (Pyrus bretschneideri Rehd) were observed and pollen activity was synthetically studied in the paper.

4 A wild mountain ash ( Pyrus decora ) of eastern North America.

5 The fruit of Western Pear(Pyrus communis L. )can produce a great deal endogenous ethylene only after harvested and start the ripening of the fruit.

6 Here,[] spring-flowering pyrus and prunus trees frame the view to the golf course while mimosa and jacaranda trees provide summertime blue and red flowers as well as cooling shade.

7 Screen the stem proliferation medium of Pyrus Pyrifolia C V.

8 The floral nectary of Pyrus bretscheidert Rehd. located on the surface of tapered disc above infloror ovary, which belonged to the disc nectary above inferior ovary.

9 The genetic characteristics of leaf characters in pear (Pyrus)hybrid were studied.

10 The volatile oil from the fruits of Pyrus betulaefolia Bunge was abstracted by steam-stilling and analyzed by GC-MS method.

11 The essential oil from the flowers of Pyrus betulaefolia Bunge was abstracted by steam-stilling and analyzed by capillary GC-MS method.

12 A widely cultivated tree(Pyrus communis) in the rose family, having glossy leaves, white flowers grouped in a corymb, and edible fruit.

13 Pyrus communis L were different in germplasm with China pear.

14 The regeneration system used by stems of one - year - old pyrus betulae folia Bge.

15 The main location, reasons and period of the freeze injure of pyrus Pingguo were investigated.

16 Effects of postharvest heating treatment on fruIt'storage quality of Pyrus pyrifolia Nakai cv.

17 It's showed that peroxidase isozyme analysis provided the basis for the classification and identification of germplasm resources of pyrus.

18 Effects of KNO3 spray on nitrate reductase activity (NRA) and nitrogen accumulation were studied in Pyrus pyrifolia cv. Niitaka seedlings grown in pots.

19 It was anatomic studied enlarging of stone cell group and the expanding of parenchyma cells during fruit development of Pyrus bretschneideri.

20 The presence of which of the following cells gives Pyrus communis L. (pears) their gritty texture?

21 Besides, in order to evaluate the transferability of the newly exploited markers across genera, primer selecting and analysis of genetic relationships of a collection of Pyrus were also conducted.

22 The research indicated that the classification system based on AFLP could reflect the genetic diversity and relationship of Pyrus species and cultivars from Gansu province.
