Abstract

The invention discloses a method for hybrid breeding of Lagerstroemia plants without male compartment isolation and bagging. The crape myrtle pistil compartment isolator is provided with a fixing device to clamp the pedicel in two sections, providing support and fixation for the crape myrtle pistil compartment isolator; the pistil isolator is linked with the fixing device to seal and fix the pedicel, and at the same time drive the pistil to isolate The stamen isolator seals and isolates the flower buds; the pistil isolator is provided with an adjustment component and a clamping element, which can adjust and fix the stamen isolator and the isolator cover according to the size and distance of the flower bud and the stigma, and finally make the lagerstroemia pistil compartment isolator fixed in the on the stalk to seal the buds.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for hybrid breeding of crape myrtle plants without sterility and compartment isolation and bagging. Background technique [0002] "Hubei Agricultural Science", Vol. 49, No. 11, November 2010, recorded the research report of Wang Ruiwen and Yang Yanling on "Research on Viability Changes of Lagerstroemia Pollen and Stigma Receptivity". The research report stated as follows: Lagerstroemia in the morning Around 4:30, the flower buds are loose, the stigma sticks out, and the top is green without mucus; 5:30-6:00 The petals begin to unfold to reveal the anthers; At 9:30, a large amount of mucus was produced, and the stigma was observed to be covered with pollen; at 16:00 in the afternoon, the calyx was closed, and the stigma was still standing outside. On the second day of flowering, the calyx is completely retracted, the curved top of the stigma is cove...
