Description
Technical field
The present invention relates to a kind of Europe Lee method for treating seeds, and in particular to a method of improve Europe Lee percentage of seedgermination.
Background technique
Europe Lee is the distinctive rare Fruit Tree Resources in China, is a kind of short raw shrub, be distributed widely in 13 provinces of northern China,
City and autonomous region.Europe Lee plant dwarfing, cold-resistant, drought resisting, resistance to ridge be thin, saline-alkali tolerant.Europe plum fruit is full of nutrition, unique flavor, i.e.,
It can eat raw, and processable.Europe Lee has wide development prospect as a kind of emerging fruit tree.Currently, the main breeding side of Europe Lee
Method has sowing, cuttage, tissue cultures, grafting etc. several.When carrying out seed propagation with Europe Lee's seed, need at seed
Reason, otherwise, seed is difficult to sprout, and germination rate is 10% or less.In order to improve the germination rate of Europe Lee's seed, produce to Europe Lee's kind
The processing of son mainly has the side of the chemistry such as growth regulatory substance processing, acid etching, Stratificated treatment, mechanical dejacketing processing, physics
Method.Wherein, growth regulatory substance facture is broken if carrying out immersion treatment with growth regulatory substances such as GA3,6-BA, NAA
The suspend mode of seed promotes its germination, handles the time 100 days or so.In operating process, it should be noted that locating later in low-temperature stratification
Reason, and the concentration of time, Auto-regulator and the wet degree of seed early period handled influences the germination rate of seed.Acid etching
Method after hydrochloric acid, dense sulfuric acid treatment mainly with keeping kind of shell thinning, an enhancing kind shell permeability, improves seed germination rate with this, operates
In the process, needing to control the time of the amount of seed and the ratio of acid, acid etching, short processing time influences treatment effect, and

Hair；In operating process, it should be noted that cleaning and water content, the low temperature of lamination and the time, lamination of the time of seed infiltration, sand
The control of the lot of essential factors such as middle gas permeability.The shortcomings that Stratificated treatment is that (1) low-temperature stratification effect is less desirable, general First Year
Germination rate 30%；(2) condition of Stratificated treatment depends on natural low temperature, and very big, germination percentage is influenced by outside environmental elements
It is unstable, there is the phenomenon that next year sprouting；(3) poor timing of Stratificated treatment usually makes Europe Lee germinateed in underground
Slow-witted overlong time, plumule growth is too long, influences survival rate after planting；(4) it needs that it is suitable to control it using clean river sand
Water content.Mechanical dejacketing processing is to carry out skin breaking to the seed that do not sprout after Stratificated treatment, and percentage of seedgermination is bright
The aobvious germination percentage higher than not broken shell seed；In operating process, it should be noted that the dynamics of decladding, the integrality for planting skin, kernel it is intact
Property.The shortcomings that mechanical dejacketing processing is that the suitable dynamics of (1) grasp decladding is difficult, general artificial bad grasp；(2) skin, kind are planted
Benevolence has the phenomenon that by destroying more, influences the germination for handling seed；(3) a large amount of seed treatment investments is artificial more.
In short, the major defect of the above technology is longer the time required to being germination；Operating process trouble；And some processing are to kind
The viability of son has an impact, therefore makes the reduction of its germination percentage.
