However , due to excessive firewood picking and over grazing , population oflongstalk peach have been decreasing dramatically in last several decades and it has become one of the potentially endangeredspecies in the region ( Zhao Yizhi , １９９１) . Previous studies have indicated that it is hard to establish seedlings of longstalk peachusing seeds collected from previous year . ( Yin Like , Wang Ye , １９９０ ) . In this study , we aimed to improve seedlingestablishing by using seed collected immediately after they are mature .Materials and methods Seeds were collected as soon as they were mature and were sowed shortly after they were collected .There were three different sowing dates for pot and field experiments which started on １０ July ( Table １ ) . In the field , seedswere sowed at ３cm in depth , ５cm between two seeds and ５０cm between two rows with . Four replications ( plots) were used ,each having ５０m２ in area . Soil in the same field was used in pot experiment which was conducted in greenhouse . Twenty seedswere sowed in each pot .Results The results are shown in Table １ . Seeds sowed in the field on １０ July , and ２０ July began to emerge on ２４ July and ７August , respectively . However , seeds sowed on ３０ July didn�t emerge . Seeds sowed in pot on １０ July , ２０ July and ３０ Julyemerged on ２６ July , １２ August and １０ September , respectively . The average height of longstalk peach seedlings sowed on １０July in the field was ３０cm , while sowed on ２０ July was ２０cm . All these seedlings emerged evenly , grew well and survived overthe coming winter . The average height of longstalk peach seedlings sowed on １０ July in pot was ３０cm , while those sowed on ２０July and on ３０ July were ２０cm and ８ cm , respectively . These seedlings stopped growing after ２０ October .It was observed that af ter mature , longstalk peach摧s seeds had no dormant period and began to emerge ２ weeks later . Thegermination rate was ８７％ in pot and ６８％ in field .Table 1 The state o f sow ing longstalk peach (Date : day /month) .sowingtime emergencetime emergencerate sowingtime emergencetime emergencerate sowingtime emergencetime emergencerateGrownin field １０ /７ 骀２４ /７ 邋６８％ ２０ /７ 滗７ /８ 档６１％ ３０ /７ 忖Grownin pot １０ /７ 骀２６ /７ 邋８７％ ２０ /７ 滗１２ /８ 沣７９％ ３０ /７ 忖１０ /９ 後６４％Conclusions Longstalk peach seeds harvested immediately when they were mature had no dormancy and could germinate andestablish at reasonable good rate when sowed after they were collected shortly . The seedlings also survived well over thecoming winter . Raising longstalk peach seedlings using current year harvested seeds is a viable method to establish longstalkpeach plants . This method is simple to adopt and requires less effort in storing seeds and establishing seedling .ReferencesZhao Yizhi , １９９１ .
