Cocoa （Theobroma cacao L.） is the major input into the chocolate manufacturing industry, particularly the fine or flavor of the indigenous variety Trinitario, which is the hybrid of Crillo and Forastero. One key problem encountered by researchers is the inability to differentiate the various phenological stages of the cocoa reproductive cycle and to assess or predict the yield. This study sets out to map the various stages of the reproductive biology of cacao and to develop a set of photographic illustrations that appropriately describe the floral biology and development stages of Caribbean free cocoa as a tool for agronomist and farmers. It used a modified version of the codification of the ＂extended BBCH＂ scale （Biologische Bundesantalt, Bundessortenamt and Chemische Industrie, Germany）, which is a numerical system that differentiates between principal, secondary and tertiary growth stages. The phases and all floral stages to fruit development are described and illustrated in a set of photographs, which can now be used for training and referencing purposes. This is the first attempt to undertake and document this study.

关键词： Cacao flavor extended BBCH fine cocoa growth stages.

Drought stress has become more common in recent years as a result of climate change impacts on the production of banana crops and other fruit *** growth and productivity of musa spp are severely impacted by the gradual degradation of water resources and the erratic distribution pattern of annual precipitation *** aim of the work includes increased drought tolerance in light of water scarcity in the world as a result of the bananas’being gluttonous for water *** investigation was carried out from 2019 to 2020 to study the effect of potassium silicate on morphological growth and biochemical parameters of musa acuminata L under drought stress by *** a result,drought stress reduced the morphological characteristics such as shoots number,shoot length,roots number,and survival percentage and biochemical characteristics such as chlorophyll a,b,carotenoids,stomatal status,and *** proline content increased in the leaf of *** *** complemented with K2SiO3(2 to 6 mM)either individually or in combination with PEG led to an improvement in all morphological and biochemical *** activities of CAT,POD,and PPO enzymes increased significantly compared to ***,the lowest PPO,CAT,and POD activity were ***,K2SiO3 treatments under drought stress successfully enhanced the leaf stomatal *** results suggest that K2SiO3 can help to maintain plant integrity in the tested cultivar under drought stress.

旨在筛选对4种植物病原真菌具有拮抗活性的甘草内生细菌,为新疆甘草内生细菌的开发应用提供理论依据。采用平板对峙培养法从100株甘草内生细菌中筛选对石榴枯萎病甘薯长喙壳、草果叶斑病镰刀菌、草果假茎黑斑病小孢拟盘多毛孢、墨兰炭疽病胶孢炭疽菌等4个病原菌具有拮抗活性的菌株,并测定其16SrRNA基因序列,建立系统发育树对其进行初步鉴定。结果显示,61株菌株对甘薯长喙壳具有拮抗作用,其中13株菌的抑菌半径均大于15mm。进一步研究表明,10株菌对4种植物病原菌都表现出较高的抑菌能力。基于16Sr RNA基因序列分析与系统发育分析表明,其中11株菌为萎缩芽孢杆菌(Bacillus atrophaeus),另外2株菌分别为副氧化微杆菌(Microbacterium paraoxydans)和莫哈韦芽胞杆菌(***)。
