Embodiment Construction

[0064] The present invention will be further described in detail below in conjunction with specific examples.

[0065] The present invention provides a method for systematically evaluating the loose powder characteristics of lily resources, taking 63 lily resources such as 'Yellow Keket' and 'Stainless Steel' as examples, including 22 Asian lily series varieties, 3 LA series varieties, and 3 LO series varieties Varieties, 15 OT series varieties, 12 Oriental lily series varieties, 2 Trumpet series varieties and 6 wild lily species. Its specific implementation example is as follows:

[0066] 1. Observe and count the number of anthers in a single flower of lily resources:

[0067] Three open lilies were randomly selected from each resource, and the number of anthers in each flower was observed and recorded.

[0068] 2. Obtain the anthers of the samples to be tested and observe whether the anthers are cracked

[0069] The dehiscence of the anthers of the lily was observed conti...

Abstract

The invention discloses a systematic evaluation method of lily resource powder characteristics and application thereof, and relates to the research field of lily reproductive biology and crossbreeding. The method comprises the following steps: (1) observing and counting single flower anther number of the lily resource; (2) obtaining anther of a sample to be measured and observing whether anther dehiscence happens; (3) measuring length, width and thickness of the anther and calculating anther size; (4) measuring pollen content of the anther and pollen content of a single flower; (5) calculating pollen content of the anther per unit volume according to the pollen content of the anther and anther size; and (6) determining apparent pollen quantity and pollen pollution to petals during the lily source powder growing period. A systematic evaluation method of lily resource powder characteristics is established in the invention. The invention lays an importation foundation for evaluation of lily resource powder characteristics, the research on reproductive development mechanism of powder quantity difference and breeding of pollen pollution-free lily new-variety.

Description

technical field [0001] The invention belongs to the field of lily reproductive biology and hybrid breeding research, and in particular relates to a method and application for systematically evaluating the loose powder characteristics of lily resources. For the pollen content of a single flower, calculate the pollen content per unit volume of the anther, observe the anther dehiscence, the apparent pollen quantity, and the characteristics of the pollen scattered on the petals, and use digital calipers, optical microscopes and other instruments to comprehensively evaluate the loose powder characteristics of lily resources. Background technique [0002] Lily has huge flowers, bright colors, and pleasant fragrance. It has a long history of cultivation and application. At present, lily has become one of the top five fresh cut flowers in the world, occupies a very important position in the world fresh cut flower market, and is also more and more widely used in gardens. The collect...
