Seedling Including Catalpa Tree, Catalpa, Golden Tree Seed Quality Inspection And Sowing

The seeds of three trees (Catalpa bungei, Catalpa ovata, Catalpa speciosa warder) that the bignoniad section catalpa belongs to studies the main body of a book for the quality testing material, fruit properties and seed to different seeds of trees has been in progress. Catalpa bungei seed having collected Nanjing, Henan Zhou Kou City, Henan Luoyang Luan Chuan county, Hubei An Lu area besides, the admeasurement having been in progress to the seed quality being unlike kind of source catalpa bungei analyses. The thesis puts into practice combining with giving birth to a child, impact of the condition having studied diversity hoards the temperature over catalpa bungei seed germination percentage, the catalpa bungei seed with kind of Hubei source is to try material and, the experiment, time, red mycin having studied the earth's surface covers, warm water is immersed handle the orthogonality having carried out catalpa bungei sowing seeds growing seedlings taking place to nursery stock. The main conclusions are as follows:1. Different source of Catalpa bungei seed have significant difference in the seed length before geting rid of the floss, after geting rid of the floss, seed width, length to width before geting rid of the floss, the weight of thousand seeds, water ratio, plumpness and germination percentage.2. 3 species of Catalpa have significant difference in the seed length before geting rid of the floss, after geting rid of the floss, seed width, length to width before geting rid of the floss, the weight of thousand seeds, water ratio, plumpness and germination percentage. Different seeds getting form different part of fruit have significant difference in the seed length before geting rid of the floss, after geting rid of the floss and plumpness, have no significant difference in the s seed width, length to width before geting rid of the floss, the weight of thousand seeds, water ratio and germination percentage.3. Diversity hoards the notable difference there existing a pole in germination percentage of catalpa bungei seed under temperature condition, disregarding the catalpa bungei being kind of Luan Chuan county source, seed still is kind of Hubei source catalpa bungei seed, the seed germination percentage is—18℃>—5℃> 5℃> 25℃.4. The orthogonality experiment Chinese catalpa trees are sown grow seedlings is unlike the difference selling the room rate of emergence, seedling height, Shan plant vane at reduced prices equal existence being notable, the effect the earth's surface is covered to rate of emergence of the nursery stock and growth situation is bigger, the different level treatment soaking time and red mycin affects warm water to rate of emergence of the nursery stock and growth situation not too, 9 of 3 factors diversity level is processing, use film mulching, warm water soak 12 hours, the effect handling without red mycin is best, the survive rate of seedling is 9.7%, Seedling height is 21.6 cm, the leaf number per plant is 15.8.
