Effects of nm Reagent on Dehiscent Fruit and Quality of Jujube
Hans Journal of Agricultural Sciences, 2017 多年来，枣果实成熟期遇到雨水开裂，严重影响枣的品质及农民的生产积极性，给枣农及当地经济带来很大的损失。本研究以陕北主栽品种木枣为材料，通过对枣果实和叶面定期喷洒不同浓度nm试剂，实地和实验室调查分析nm试剂对枣裂果及枣果大小和重量的影响。结果表明：1) 不同浓度nm试剂的喷施，可大大降低裂果率，有效减少裂果的发生，但不同处理间差异并不显著；2) 不同浓度nm试剂的喷施，可增大枣果横径，其中nm-2、nm-3处理效果最好；3) nm-2、nm-3、nm-4处理可增大枣果纵径；4) 可增大枣果的重量，nm-2浓度水平效果较好。总之，不同浓度nm试剂的处理，除了具有可观的防裂效果，还可从一定程度提高枣果产量，既改良了品质又提高了产量。其中，nm-2浓度水平效果最好，推荐该浓度试剂在生产上应用推广 ...

Development of the pericarp, septa and zone of dehiscence in the fruit of Cassia tora L.
Acta Societatis Botanicorum Poloniae, 2014 The pod of <em>Cassia tora</em> is the product of a single carpel consisting of 20-30 seeds enclosed one in each compartment formed by the ingrowth of the endocarpic tissue. There are three distinct histological zones of the pericarp Epicarp (a), Mesocarp (b) and Endocarp (c). The paracytic stomata and uniseriate multicellular trichomes are

PLANTS, PEOPLE, PLANET, EarlyView.This study examines how the fruits of non‐photosynthetic forest plants in the Monotropoideae (Ericaceae) have evolved into the diversity observed today. By analyzing four Asian species, we identified a shift from dry, dehiscent fruits that release seeds into the air to fleshy, berry‐like fruits adapted for animal dispersal.

PLANTS, PEOPLE, PLANET, EarlyView.Tiny, leafless fairy lanterns are easily overlooked on the forest floor. Thismia abei, endemic to Japan, persists in small, unstable populations and is listed nationally as Critically Endangered. Our recent work has revealed another, less obvious form of obscurity.

Study of some abnormalities of ovule development to seed in Pistacia vera L. [PDF]
Zīst/shināsī-i Giyāhī-i Īrān, 2014 Seed production in some crops like pistachio is limited by some abnormalities in ovule development stages. In this study, the ovule developmental stages as well as abnormalities of these stages were investigated.

Ants contribute to raspberry pollination in protected cropping systems
Agricultural and Forest Entomology, EarlyView.Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Agricultural and Forest Entomology, EarlyView.We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...
